Summary of Research

I study computational kernels to accelerate a broad spectrum of scientific computing applications; much of this work focuses on minimizing communication, which encompasses both DRAM-cache memory traffic in shared memory settings and processor-to-processor communication in distributed memory settings. I'm thrilled to be advised by James Demmel and Aydin Buluc at UC Berkeley.

Some of my recent interests include mixed precision matrix multiplication and various operations involving sparse and dense matrices, such as sampled-dense-dense matrix multiplication. Applications of the latter kernel include matrix factorization, document distance clustering, and graph neural network training.

I earned my undergraduate degree at Caltech in mathematics and computer science. I was fortunate enough to receive mentorship from Chris Umans, Mikhail Shapiro, and Rose Yu. You can find more details about me on my personal website.
