About me

I am a fourth-year Ph.D. student in ECE at the University of Washington, advised by Prof. Jenq-Neng Hwang. My current research interests lie in object recognition with the imbalance and open-set data, and multi-object tracking.

I was an undergraduate student at Beijing University of Posts and Telecommunications, advised by Prof. Chuan Wang and Prof. Weihong Deng. I was also fortunate to work with Prof. Huijun Chen @TsingHua University, Prof. Chun Yuan @UW, and Prof. Bruno Madore @Harward Medical School on medical imaging.
