[CV]

I am a research scientist at Meta Reality Labs. Prior to that, I obtained Ph.D. from Department of Electrical and Computer Engineering at Princeton University in 2021, advised by Prof. Ruby B. Lee. I received B.E. in Electronic Information Engineering from University of Science and Technology of China (USTC) in 2015, respectively.

My research interests are in AI security and privacy, multi-modal ML, and efficient models. I love building deep learning systems and further strenghtening them. I have published multiple research papers in top AI, Security and System venues, e.g., CVPR, AAAI, MICRO, HPCA, and ACSAC.
