I am an Assistant Professor in the School of Electrical and Computer Engineering at Cornell University and a member of the Computer Systems Laboratory.

I am broadly interested in computer systems and networks. Including programmable network devices, interconnect protocols, and software system stacks for achieve high-performance communication in data centers.

I was a recipient of 2025 Google ML and Systems Junior Faculty Award, 2024 MIT EECS Rising Star, 2023 Google Ph.D. Fellowship and 2021 Meta Ph.D. Fellowship.

Prior to joining Cornell, I earned my Ph.D. in Computer Science from UT Austin in 2025. I was part of the University of Texas Networked Systems (UTNS) Lab, adivised by Aditya Akella.

📌I am actively looking for self-motivated Ph.D. students in CS or ECE who are interested in networking, systems, accelerators, or hardware compilers. If you are interested in any of these areas, please reach out via email!
