CPU Architect

Biography

I am a CPU architect working on high-performance RISC-V processors at Tenstorrent. I received my Ph.D. degree in Electrical and Computer Engineering from Cornell University, advised by Prof. Christopher Batten. My Ph.D. research focused on efficient parallel framework for heterogeneous multi-/many-core systems, area-/power-efficient support for next-generation vector architectures, and sparse matrix computation on matrix architectures.

Prior to joining Cornell, I received my Bachelors in Computer Science from University of Mississippi in 2016. I worked as a research co-op at AMD Research on modeling AMD’s next-generation GPU’s cache system and developing a cache coherence testing framework in gem5 simulator in 2017. During my PhD, I interned at Arm Research to explore wafer-scale many-core architecture and Arm’s Scalable Matrix Extension (SME).

Here is my CV (Updated on 09/08/2024).
