About

I'm a PhD student at Harvard advised by David Brooks and Gu-Yeon Wei. I’m honored to be supported by the NSF Graduate Research Fellowship. My interests span heterogeneous and configurable accelerators, GPU systems, and networking for efficient AI workloads. I work across hardware and software to understand compute, memory, and communication costs in system performance and energy efficiency.

Previously, I studied computer science at UC Berkeley, worked in the SLICE Lab with John Wawrzynek and Krste Asanović, and received a SCALE Scholarship in 2024. I've interned on architecture at NVIDIA and CPU performance and GPU RTL design at Apple.
