I'm a Ph.D. student in Computer Science at UC San Diego, advised by Prof. Xinyu Zhang.

My research bridges Differentiable Rendering, Electromagnetic (RF) Simulation, and Wireless System Design — targeting physically accurate channel modeling and next-generation 6G wireless applications.

Previously, I interned at Microsoft Research Asia with Prof. Lili Qiu. Before joining UCSD, I worked at META Lab (CU Denver) with Prof. Zhengxiong Li. I earned my B.S. in Computer Science with honors from the University at Buffalo in 3 years (2021), where I was a research assistant at ESC Group advised by Prof. Wenyao Xu.
