  • Environmental Noise Monitoring and Modeling

    I am working with Dr. Transtrum and graduate students on a project to use machine learning and geospatial features (nighttime radiance, precipitation, forests, etc.) to predict ambient soundscapes throughout the U.S., and eventually, globally.  We have a need for 1-2 outdoor-oriented students interested in conducting making sound measurements in different urban and rural environments, formatting the data outputs, analyzing them, and helping to feed them into the machine learning models created by the graduate students. 

  • Machine learning and crowd noise

    This project, with Dr. Transtrum, combines machine learning with crowd noise at sporting events. We want to detect cheering, booing, or even the beginning of crowd violence. This could involve taking data, analyzing them for features that relate to crowd engagement or sentiment, or developing new machine learning models.

    We are currently looking for two students, one on the acoustics side for measurement and analysis, and one on the machine learning side.

  • Military jet noise

    We study the noise radiation from turbulent jet engine exhausts.  We've studied the F-22, the F-35, and the T-7A using lots of different methods for the Air Force and the Navy.

    I'm looking for 1-2 students to join this group of ~5 students. 

  • Passive acoustical monitoring of wildlife

    Passive acoustic monitoring of wildlife has many purposes, but include studying population health, size, and dynamics.  We're currently doing research at the Bear River Migratory Bird Refuge, looking at how water and other environmental factors impact bird choruses.  We may also be starting to do rocket noise-related research - as launches can affect noise sensitive species - in California.

    I'm looking for a student interested in measurements and analysis.

  • Research in shock waves and high-amplitude acoustics

    A lot of my research involves high-amplitude noise, like jets, rockets, explosions, and sonic booms. Other possibilities exist - email me to set up an appointment.  Numerous publication opportunities are likely.

    I'm *always* looking for new students in this area. Right now I'm looking for 2-3 students.

  • Computational Underwater Acoustics

    Large arrays of hydrophones in the ocean can be used to locate acoustic sources.  The reliability of these localization algorithms depends on the degree to which the ocean environment is correctly parameterized in the models.  

    The computational models for sound propagation in the ocean depend on the ocean environment.  My work involves using sound from the ocean to estimate the ocean environment.  One part of the research works on determining the sensitivity of different seafloor parameters and determining which seafloors make a big enough difference on the sound propagation to be detected.  The other part explores optimizations and how machine learning can be used to identify seafloor properties from different types of sounds.

    I am currently looking for two students to join my computational underwater acoustics research.  Research in this area will provide a strong foundation in computational skills, numerical modeling, and deep learning, all of which will prepare students for additional opportunities in industry, national laboratories, and graduate school.

  • Underwater Acoustical Measurements

    Our underwater acoustics lab (U117) has a fully automated system for making acoustic measurements in our water tank (12 ft long by 4 ft wide).  Currently measurements are being made test which numerical models accurately predict sound propagation in the tank at ultrasonic frequencies.  The big upcoming goal is to be able to test machine learning algorithms for source localization and environmental variability using ultrasonic tank measurements.

    I am currently looking for two students to join my underwater acoustical measurement group.  The opportunity to do experiments in a water tank at ultrasonic frequencies offers a solid foundation for students interested in studying ultrasound or other medical physics fields in graduate school.  In addition, the experience with measurement protocols, programming the robotic arms, and analyzing the data with signal processing techniques provide a good foundation for many technical jobs.

  • Building an Atlas of Molecular Gas Kinematics From the ALMA Archive

    Archival data from the Atacama Large Millimeter/submillimeter Array (ALMA) reveal molecular gas in many early-type galaxies (ETGs, including elliptical and S0 types). In many cases, the observations trace regular rotation about the galaxy center. However, relatively few of these data sets have been published, and there is little consistency between the published data products. We are uniformly measuring gas properties in a large sample of ETGs with ALMA carbon monoxide (CO) observations, which will then be compiled into an atlas of molecular gas kinematics in luminous galaxies. In addition to measuring and analyzing kinematic properties, this atlas will also help identify candidates for higher angular resolution ALMA imaging to measure the mass of the central supermassive black hole mass.

    I am currently not looking for additional students to work on this project.

  • Dust Properties From ALMA Observations

    Cold dust found at the centers of many nearby galaxies emits thermal radiation. With typical temperatures of 10-30 K, the dust black body spectrum peaks in the far-IR range. In many cases, the Rayleigh-Jeans tail of the dust thermal emission is detectable at mm-wavelengths with the Atacama Large Millimeter/submillimeter Array (ALMA). Together with continuum measurements from the radio to the mid-IR, data points at ALMA wavelengths are important when measuring dust mass and temperature. We are measuring ALMA continuum flux densities (or upper limits) and building spectral energy distributions (SEDs) to separate out non-thermal contributions and model the SEDs as using a modified black body function.

    I am currently not looking for additional students to work on this project.

  • Monitoring AGN Variability Using West Mountain Observatory

    Active galactic nuclei (AGN) are electromagnetic phenomenon arising from material accreting onto supermassive black holes (BHs). Certain types of AGN called blazars display high levels of variability over timescales of minutes to years. Blazars are thought to be AGN seen down the jet that launches from directly about the BH. Using a rich data set of several blazars taken with our own West Mountain Observatory spanning about a decade, we aim to better characterize both long timescale and intra-night variability. This project will use both differential (aperture) photometry and, when possible, difference imaging to build detailed light curves. We will also explore possible systematic effects that impact our final light curve error budgets and more fully capture the inherent uncertainties in aperture photometry.

    I am currently looking for students to work on this project.

  • Reverberation Mapping in Active Galactic Nuclei

    Active galactic nuclei (AGN) manifest a range of phenomenon in X-ray to radio wavelengths, from active accretion of material into a thermally hot disk about the central supermassive black hole (BH) to ionization of clouds at light-day distances to massive jets of material that produce significant radio emission. In this project, we seek to better understand the connection between brightening and dimming of thermal energy from the accretion disk and the strength of emission lines from ionized gas clouds in what is called the broad line region (BLR). As the accretion disk light produces the light that ionizes the surrounding gas clouds, changes in accretion-disk luminosity reverberate throughout the region, resulting in a time delay between AGN and BLR light curves. In collaboration with researchers at the University of Wyoming, we will employ optical imaging and spectroscopy as well as near-IR spectroscopy to map the response of a variety of BLR emission lines to the driving continuum.

    I am currently looking for additional students to work on this project.

  • Supermassive Black Hole Mass Measurement

    The improved sensitivity and larger baselines of the Atacama Large Millimeter/submillimeter Array (ALMA) now enable imaging of molecular gas deep within the centers of numerous nearby galaxies. In a small percentage of luminous elliptical galaxies, ALMA observations trace the motion of molecules like carbon monoxide (CO) well within the supermassive black hole's (BHs) sphere of influence, wherein the BH dominates the overall gravitational potential. Using detailed gas-dynamical models, we are able to measure the BH mass and determine its overall error budget.

    I am currently looking for additional students to work on this project.

  • Astronomy Education

    I'm currently working on a project to develop a High School research competition based on pulsating variable stars.  This is funded by a NASA Rocky Mountain Space Grant Consortium Mini Grant.  We will provide variable star data to a number of high school teams that will then analyze the data and provide a final report that will be judged.  

  • Impact of CO Bands in Cepheids on the Hubble Tension

    We are exploring the changes of Carbon-Monoxide molecular bands over the pulsation cycle of Cepheids variables. The growth of these bands could have an impact on the Hubble Tension. This is done in the Near-IR with the ARC 3.5-m telescope. This allows complete coverage of the phase curve, which is not possible in the Mid-IR (MIR) with systems like the JWST.

  • Light Curve Generation for Transiting Planets, Eclipsing Binaries, and Pulsating Variables

    We have developed a number of robotic telescope systems on the observation deck of the Eyring Science Center.  These range from 6" and 24".  Most of the systems are currently capable of working the entire night robotically.  We observe transiting planets, eclipsing binary systems, pulsating variables, and other systems that change in brightness. In some cases we really want to process the data as soon as possible to get the data sent to programs like the NASA TESS transit finding program.  With the amount of data generated we just need help in processing the data.  If someone were to work on this program they would get experience over a wide range of objects.

    Always looking for new research students on these projects.

  • Matching Model Stellar Atmosphere Models to Near-IR spectra of Pulsating Stars

    The Near-IR is an area that hasn't been extensively explored for pulsating variable stars. We are obtaining NIR spectra of the stars of the instability strip (Cepheids, RR Lyrae, delta Scuti, etc.) to study a number of different issues. This includes looking for cool companion stars, molecular banding structures, line-profile changes over pulsation phases.  Some of these could be related to the Hubble Tension issue.

  • Period Changes in Medium Amplitude delta Scuti Variables

    In general, researchers consider there to be two groups of delta Scuti variables; the High Amplitude delta Scuti (HADS) and the Low Amplitude delta Scuti (LADS). However, the in between realm is interesting. The Medium Amplitide delta Scuti stars seems to show a range of changes in both amplitude and period. This makes them a very interesting group to monitor.

    We are now adding some computer modeling to try to better understand these changes.

    This is a place where there is always need for additional help.  We will have 6 robotic telescopes running on every clear night by the summer of 2022.  That means a lot of data to process and light curves to be determined.

  • Spectrophotometic Comparison of H-alpha and H-beta Index

    Traditionally the H-beta index has been used as a reddening free index to measure the surface temperature of stars. Prof. Joner in the department has developed a new H-alpha index that has great promise. We are working together to spectrophotometrically compare the two systems and the application of the system to a number of different types of objects.

  • Spectroscopic Survey of Northern Sky delta Scuti Variables

    To understand the nature of the delta Scuti variables in the instability strip one needs as much information as possible about the stars. However, an examination of the catalog of delta Scuti variables shows a lack of basic information on many of the group. Of the 247 delta Scuti stars visible in the northern hemisphere we currently have spectra of 242 of them. These need to be reduced to provide estimates of some basic stellar properties like [Fe/H], radial velocity, rotational velocity, and perhaps information on any binary companions.

  • Variable Star Search in Open Clusters

    We are currently searching for new low amplitude variable stars in a large sample of open clusters. The clusters cover a wide range of ages and will provide a evolutionary test of how the variable stars change with age. We are also looking for very small eclipses that might be the sign of a planet.

  • Photometric Reverberation Mapping
    Traditional reverberation mapping to estimate AGN black hole masses uses a combination of photometry and spectroscopy to determine the time lag between variations that occur at the accretion disk and then later in the broad line region. With such techniques, there is a need for a large amount of moderate to large telescope time in order to secure the spectroscopic data with an observing cadence suitable for a determination of the time lag. Photometric reverberation mapping uses a single epoch spectroscopic determination of the broad line region velocity and a time lag determination based on photometric observations that include predominantly continuum features or broad line components that can be seen to vary at a later time. This technique is still being tested but hold promise for the determination of black hole masses in the age of several large scale surveys.

  • Low surface brightness Universe

    An important change has occurred in our visualization of faint structures in the cosmic space during the past decade: deep optical surveys have become important observational tools for probing the low surface brightness Universe. Modest size telescopes with a large field of view, supported by observations on large telescopes, use special observational techniques to collect sufficient amount of light for distinguishing very faint details around galaxies. I provide multiple projects related to the low surface brightness Universe based on deep optical observations using the ARC 3.5m telescope, WMO, and other modest size telescopes. An REU student would participate in observations, reduce and analyze data, and develop basic computational skills. An important part of the project is a valuable contribution to a publication and/or conference proceeding.

  • Orbits in the Outer Solar System

    (No positions open until Fall 2023.) Beyond the orbit of Neptune lies a population of icy bodies whose orbits can reveal unique information about how our solar system formed. This region of the solar system is called the Kuiper Belt and these small icy bodies are called Kuiper Belt Objects (KBOs or sometimes Trans-Neptunian Objects or TNOs), though some are large enough to also qualify as "dwarf planets" like Pluto and Haumea. There are multiple projects available in my research group to study KBO satellites (e.g., Haumea's moons) and KBO orbits (e.g., the Haumea and other collisional families). There are a variety of projects available at a variety of levels and you'll be paid as Research Assistants. Please contact me for more information. The best time to contact me about available positions is about 1 month before the beginning of a semester. 

  • Studying the Architectures of Exoplanetary Systems

    (No positions open until Fall 2023.)  Like our Sun, other stars are known to host planetary systems. As we continued to discover many more exoplanetary systems, we learn about how these systems are put together. The "architecture" of these systems (are small planets on the inside or outside? how close are the planets to each other? etc.) gives us invaluable clues to the formation of planetary systems. I used state-of-the-art statistical and computational techniques to discovery new exoplanetary systems, study existing systems, and remove the biases on their properties from our limited observational methods. There are a variety of projects available at a variety of levels and you'll be paid as Research Assistants. Please contact me for more information.

  • Brown Dwarf Binary Systems - modeling

    Looking at peculiarities in the spectra of known binary brown dwarfs. Trying to understand the large number of L/T transition binaries, and why the spectra of these objects change so quickly over a constant temperature range. We want to determine binary statistics with spectral type, and how many of the L/T objects are truly single objects. We want to understand which spectral features vary the most between a single brown dwarf and an unresolved binary system, so we can use these spectral features as a way to identify binaries from existing spectra. Eventually we will use high resolution photometry and psf fitting to identify marginally resolved and unresolved binaries.

  • Education - Learn Astropy and create training videos

    I would love to have a student work through several tutorials I have that teach astropy, learn it very well, and then create zoom videos and jupyter notebooks that future students can use to learn how to use astropy to do photometry and spectroscopy.  They could even extend this beyond to creating notebooks and videos to reduce TESS data (or any data from the roof) and in the future notebooks that can reduce APO data.

  • Spectrophotometry of brown dwarfs observed with ARC 3.5 meter

    Use IDL to reduce spectra of brown dwarfs taken with the ARC 3.5 meter telescope.  

  • Transiting Exoplanets
    Take data with the 16" telescope on the roof of the Eyring Science Center of stars that may have transiting planets.  Reduce this data using IRAF and AstroimageJ software.  Characterize the radius of the planet (if we see a transit) by fitting the transit light curve.  Return results to the team so that we can either obtain further observations of a possible planet candidate or expire the target as spurious or an eclipsing binary star system.
  • Variability in Brown Dwarfs
    Reduce Spitzer observations of 3 brown dwarfs taken sequentially in time to look for evidence of variability. If variability exists, the amplitude is very low. The evidence of variability would suggest that cloud features or holes in the clouds are not homogeneously distributed across the surface.

  • Advanced Mirror Coatings for Hubble's successor
    In 1999 the IMAGE spacecraft was successfully launched and functioned for over 6 years studying the various plasma filled regions surrounding the earth (ionosphere to magnetosphere) in wavelengths from radio through EUV. We designed and coated mirrors for the Extreme Ultraviolet Imager (EUVI) instrument, which was one of about four observational components of the IMAGE Mission. IMAGE, which stands for Imager for Magnetopause to Aurora Global Exploration, was a NASA funded Medium Explorer (MIDEX) program) [1].

  • Ultra-cold Plasmas

    We are making ultra-cold plasma by photo-ionizing laser-cooled calcium atoms in a Magneto-Optical Trap (MOT). The trap size is about 1 mm and it holds about 10 million calcium atoms at a temperature of 0.001 K above absolute zero. The ultracold plasma is formed when we shine in two laser pulses that ionize all of the atoms.

    The plasma is "strongly coupled", meaning that the average "nearest-neighbor" Coulomb energy is orders of magnitude larger than the mean thermal energy of particles in the plasma. A strongly coupled plasma behaves in some ways more like a solid than a gas. One of our major research goals is to understand how strong coupling changes basic processes like recombination and collisional ionization.

    We use calcium to create this plasma because the energy level scheme in Ca is favorable for laser cooling and trapping. The blue wavelengths for both Ca and Ca+ are easily generated with standard laser technology. So when plasma is created we can measure the ion temperature and plasma density in a straightforward manner.

    Our newest two projects are using lasers to cool the ions in the plasma, and also generating a plasma with both Ca and Yb ions at the same time. This last project will allow us to study the approach to thermal equilibrium in a two-temperature and two-mass system.

  • Imaging atomic strain in structural materials

    We are studying metals at the nanometer scale to understand how and where structural materials fail. Using a lensless x-ray imaging technique known as Bragg coherent diffraction imaging, we are imaging the strain in metal grains under tension, compression, or high heat environments. This technique can currently provide 3D strain imaging at few nanometer resolution. Under support from the United States Department of Energy's Basic Energy Sciences Program, we are pushing this technique towards atomic resolution and in multiple grains.

  • Single shot imaging of materials in extreme conditions

    We use single, ultrafast x-ray pulses from an x-ray free electron laser to image materials while they are being shocked with high power laser systems. This research has applications to inertial confinement fusion energy applications. It is funded by the Department of Energy through SLAC National Accelerator Laboratory.

  • Magnetic imaging

    We use Magnetic Force Microscopy (MFM) to image magnetic domains in ferrmagnetic thin films.

  • 2D metal-halide perovskites for solar applications

    "2D hybrid organic-inorganic metal halide perovskites" are a recently discovered class of semiconductors being studied in the hopes of developing highly efficient, low-cost, stable solar cells. Metal and halogen (group VII) atoms bind together in 2D layers, which are then stacked together via organic linker molecules. We are studying these interesting and important materials through optical absorption, electric field-modulated absorption, photoluminescence (fluorescence), time-dependent photoluminescence on nanosecond time scales, and dielectric spectroscopies. This allows us to determine important properties of the electrons inside these materials, to make better photovoltaic materials.

  • Nanoparticles as temperature sensors
    We're working with a mechanical engineering professor (Troy Munro) to use semiconductor nanoparticles as temperature sensors. The wavelengths of light present in the nanoparticles' photoluminescence (aka fluorescence), and the time it takes for the luminescence to be emitted after the electrons have been excited both depend on the temperature. By characterizing the nanoparticles’ photoluminescence spectrum in both wavelength and time as a function of temperature, we hope to be able to use the nanoparticles as non-invasive temperature sensors in e.g. medical applications. For example, one could use the optical emission from nanoparticles injected into tissue to monitor temperatures as focused ultrasound is used to heat up and destroy tumors.

  • Atomic and magnetic structure investigations of quantum materials and technologically relevant materials

    One of the first steps toward understanding any given material of interest (a new superconductor, an unusual magnetic material, an energy-related compound, etc) is determining its atomic and magnetic structure. We utilize beams of x-rays, neutrons, and muons at large-scale accelerator facilities to do just that. Our primary experimental techniques include atomic and magnetic pair distribution function (PDF) analysis, conventional x-ray and neutron scattering, and muon spin relaxation/rotation. A few times a year, we visit these types of facilities to collect data, and then we come back home to analyze and make sense of it all. Through this process, we hope to shed light on the origin of the material's properties by gaining a detailed understanding of the local and average atomic and magnetic structure. If you are interested, please reach out and we can discuss if a spot is available!

  • Developing open source, python-based software for investigating atomic and magnetic structure

    Data are only useful if we can understand them, and to understand them, we often need specialized tools. We are currently developing open source, python-based software tools to analyze experimental data collected from condensed matter experiments using x-ray, neutron, and muon beams. The software will maximize research effectiveness and enable new methods of analysis not only for our own research group, but also for the wider community of condensed matter physicists using similar types of experimental methods. If you are interested, please reach out and we can discuss if a spot is available! 

  • Investigating the structure of molten salts for alternative nuclear reactor designs

    Molten salt reactors (MSRs) are a promising nuclear reactor design concept in which molten ionic salts function as the coolant and/or fuel source in the reactor. MSRs have many potential advantages over standard designs in commercial use today, including greatly enhanced safety/security and the ability to produce critical medical radioisotopes in addition to vast amounts of carbon-free electricity. To make MSRs a reality, it is necessary to understand and predict the behavior of the salts in operating conditions. Gaining a detailed knowledge of the local structure of the molten salts on the atomic scale is an essential step in this direction, since the local interactions between constituent atoms determine the macroscopic properties. In this project, we use cutting-edge neutron and x-ray total scattering and computational modeling techniques to establish the structure of relevant molten salts. If you are interested, please reach out and we can discuss if a spot is available!

  • Machine Learning for Discovering New Materials

    We are developing mathematics, algorithms, and software to discover the new materials that will define the next age of human civilization. Stone, Bronze, Iron, Steel, Silcon,...what material will define the next age? We are building a "virtual laboratory" so that artificially intelligent computers can discover the materials of tomorrow. Students with no prior experience are welcome.

  • Materials simulation: Algorithm development and applications

    Our group focuses on computer simulation of materials for the purpose of discovering new materials that have exceptional properties. There are two aspects of the research: 1) developing new approaches, algorithms, and mathematics that can be used in simulation, and 2) applying existing and new approaches to find new materials. Both aspects are challenging and require participating students to move far outside their comfort zone and learn things that won't be part of a regular physics or CS degree. Students with no prior experience are welcome.

  • Computational methods for exploring high-dimensional parameter spaces
    Modern computers enable large models of complex processes.  These models often involve a large number of parameters and a relevant question is often how the model's behavior depends on the parameter values.  Because the parameter space is high-dimensional, a brute force search will never be possible for models with more than a few parameters.  We are developing novel computational methods for efficiently and intelligently exploring these high-dimensional parameter spaces.  This project uses theoretical insights based on information theory and applies sophisticated techniques in computational differential geometry, automatic differentiation, and topology with high-performance computing.  Our goal is to improve algorithms for fitting models to data, performing statistical sampling, and classifying regimes of distinct model behaviors. 
  • Information theory of multi-parameter models
    Mathematical modeling is a central component of nearly all scientific inquiry.  Parsimonious representations of physical systems, together with robust methods for interacting with them, is one of the primary engines of scientific progress.  Much of the work in our group involves developing new methods, both theoretical and computational, for improving the predictive performance of complex multi-parameter models.  Our research explores the mathematical structures that enable predictive modeling.  We use information theory, statistics, differential geometry, and topology, as well as relevant physical laws from a variety of fields to better understand data, models, and the relationship between reductionism and emergence.
  • Machine Learning on Acoustic data sets
    Sound is one of the fundamental ways we observe our environment.  In collaboration with acousticians at BYU and Blue Ridge Research and Consulting, we use machine learning techniques to predict ambient sound levels from environmental parameters (such as the distance to a road or local population densities).  Our models will ultimately be useful for a variety of applications including military mission planning, public health, urban development, and ecology.  We also use machine learning to predict crowd dynamics from acoustic data sets.  Can analysis of acoustic data collected at sporting events be used to infer the shifting mood of a diverse crowd?  If so, can acoustic monitoring be used to improve law enforcement responses to crowds before they become violent?
  • Modeling Complex Biological Systems
    Biological systems are rich in the types of behavior they can exhibit.  This is enabled through a complex web of components.  In the case of development biology, the relevant components are networks of chemical reactions while in neuroscience, it is a combination of electrical and biochemical signals.  In both cases, the complex system responds to external stimuli and performs calculations to formulate an appropriate response.  The complexity of these systems is overwhelming.  New theoretical and computational tools are needed to organize our knowledge of these processes and compress it into a coherent theory.  Our research tries to develop minimal models from these "parts lists" in order to summarize and organize our understanding of biological and neurological processes.
  • Modeling Complex Energy Systems
    Models of energy systems involve a large number of heterogeneous components connected in complex networks.  Detailed models of these systems constructed from physical first principles are similarly complicated and involve a large number of unknown parameters.  In spite of their detail and complexity, models often have limited predictive capability because it is difficult to identify the model, i.e., find accurate values for all of the parameters.  Our goals it develop models that are sufficiently complex to capture the rich behavior of real power systems, but simple enough so that all the parameters can be learned from data.
  • Superconducting Materials for next generation particle accelerators
    Particle accelerators are are foundational technology in modern science, enabling fundamental research in facilities such as the Large Hadron Collider (LHC), as well as providing some of our best sources of coherent x-rays for probing nanoscale structure in materials.  The same physical principles underly other technologies such as electron microscopy. Superconducting resonance cavities are the enabling technology that allows subatomic particles to be accelerated to near light speeds.  In collaboration with researchers at the Center for Bright Beams (, we are working to better understand materials properties of superconductors in order to lay the foundation for the next generation of particle accelerators.  Our work uses high performance computing to solve equations that describe how specific materials respond to applied magnetic fields, accounting for details such as surface roughness, grain boundaries, and material inhomogeneities.

  • Atomic and near atomic scale studies of materials by Transmission Electron Microscopy.
    We attempt to determine in as direct observational way as possible the way materials actually chose to arrange themselves. This is often in contrast to how man has attempted to arrange them. We are interested in the structural arrangement of atoms as well as the elemental and bonding arrangements of atoms within nanometer scale features of the sample. An undergraduate would learn to prepare samples for TEM analysis as well as learn the basics of TEM operation to analyze their samples in the TEM.

    This work involves large scale computation and necessitates developing numerical algorithms for solving the nonlinear partial differential equations of general relativity and radiation magnetohydrodynamics.

  • General Relativity
    General relativity describes gravitational phenomena geometrically as curvature in spacetime: Matter curves space, and the spacetime curvature affects matter. General relativity predicts that accelerating objects can emit gravitational radiation. While this radiation is typically extremely weak, some astrophysical systems, such as colliding black holes or neutron stars, may emit gravitational waves that we can detect on Earth. Large, kilometer scale laser interferometers, such as LIGO, are being constructed to study gravitational wave signals from these events. Unfortunately, we currently know very little about the radiation expected from the regions of spacetime with the strongest (nonlinear) gravitational fields. I study computational methods for solving the Einstein equations for these strong-field gravitational wave sources. Various projects are available to investigate black hole spacetimes, black hole formation, and properties of the Einstein equations. All projects require writing, testing, and running computer codes to investigate nonlinear gravitational phenomena.
  • Numerical methods
    Research with the Einstein equations and RFD requires sophisticated numerical methods and techniques (as well as cheats and tricks). Some techniques include adaptive mesh refinement (AMR), parallel computing, high-resolution shock-capturing methods for fluid equations. Some systems, such as moving black holes, may naturally be solved in multiple reference frames simultaneously. I am investigating the use of overlapping computational grids for these problems. One particular interest is combining modern fluid methods with overlapping grids.
  • Relativistic fluid dynamics (RFD)
    Neutron star collapse, supernovae, gamma-ray sources, etc., are some of the exciting topics in relativistic astrophysics, and the perfect fluid is the fundamental model for all of these. I study relativistic perfect fluids near black holes using computational methods. In particular, Eric Hirschmann, Steven Millward and I at BYU are studying a magnetized fluid around a black hole with computational Magneto-Hydrodynamics (MHD). Various computational projects are available in RFD and MHD, which require writing, testing and running computer programs to model relativistic fluids.
