Hi! 👋 I am a PhD student in the CSEM program at the Oden Institute for Computational Engineering & Sciences where I am advised by George Biros in the Parallel Algorithms for Data Science and Simulation Group.

My graduate work investigates methods that quickly and accurately approximate information as it radiates from a source. These methods are the applied to find solutions to N-body problems with algebraically decaying kernels in linear or log-linear time. Such N-body problems are prevalent in mathematical physics – e.g., electrostatics, molecular dynamics, potential theory. My group applies these methods to the Nyström discretization of the Stokes boundary integral equation for blood capsule simulation, and I specialize in designing and implementing performance portable algorithms (i.e., efficiently executable on CPUs and GPUs from different vendors) for such applications.
