I aim to make it easy to program sparse computing applications that can run everywhere with end-to-end performance that matches or exceeds the best hand-optimized codes. A sparse application computes on a system where most parts do not interact—they are sparsely interconnected. Examples include sparse matrices, meshes, and graphical arrangements used to simulate the dynamics of robots, optimize the flow of traffic, compute the rank of web pages, estimate the similarity of genome loci, or train sparse deep neural networks. Sparse computing is ubiquitous and will become increasingly important with the growth of robotic and autonomous vehicle applications, data analytics, and machine learning.
Throughout my PhD studies, I have developed the taco compiler for computing sparse tensor expressions and the Simit programming language for computing on sparse systems. My broad research interests include compilers, programming models and languages, parallel computing, software engineering, and performance engineering.
News
I am co-organizing an Invited Workshop on Compiler Techniques for Sparse Tensor Algebra that will bring together researchers from twenty universities, companies, and national labs to discuss approaches to sparse tensor computation, how they relate, and how ideas can be combined.
