About Me

Hi, I'm Sam, a first-year PhD student in Computer Science at Carnegie Mellon University.

I am advised by Prof. Andy Pavlo and Prof. Todd Mowry.

My research explores how compilation techniques can improve database system performance.

I earned my undergraduate degree in Software Engineering from The University of Sydney.

During my time there, I worked with Prof. Bernhard Scholz on automatic index selection and automatic join optimization for Soufflé.

I also worked as a Compiler Engineer at Apple, where I helped ship Metal accelerated GPU rendering in Blender 3.1.
