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 used to solve 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.
