About me

I am an engineer on the machine learning compiler team at AMD. There, I contribute to the MLIR-based high-performance ML infrastructure we are developing, and im integrating the research I did during my Master’s/PhD at UW in a real-world setting.

I’m not looking for work right now and do not want to hear from recruiters.

I’ve been a PhD student at the University of Washington Paul G. Allen School of Computer Science & Engineering for three years, and am leaving the program indefinitely to find a more applied role and gain more real-world experience. I worked in the Programming Languages and Software Engineering group, and am advised by Rastislav Bodik. My research focus is on using program synthesis to improve the performance of numerical computations, such as matrix multiplication and convolution, that are used in machine learning and scientific computing.

I have developed a new synthesis technique for fixed-sized mathematical operators on accelerators (such as GPUs) that reduces the problem to synthesis over functional array programs and uses an abstract reachability analysis to quickly prune most incorrect partial candidates. This has the added advantage of reducing a large amount of the computation to Boolean matrix multiplication, enabling synthesis over larger spaces of functions as compared to previous work. In the future, this work will be integrated into a larger framework for synthesizing efficient code for machine learning models on accelerators.
