I am currently a Postdoctoral Researcher at the MIT Computer Science and Artificial Intelligence Laboratory (CSAIL) working with Julian Shun. I will be joining the UBC Department of Computer Science as an assistant professor in January 2025.

I recieved my Ph.D. from Carnegie Mellon University, where I was advised by Guy Blelloch. Before that, I did my undergraduate studies at the University of Toronto, where I was mentored by Faith Ellen and Toniann Pitassi.

My research interests are in developing high-performance concurrent algorithms for modern computer systems. My research has focused on designing general, easy-to-use, and efficient techniques for concurrent programming.
