I am an Applied Scientist at Amazon AWS AI Labs. I did my Ph.D. in Computer Science of University of North Carolina at Chapel Hill, working with Prof. Marc Niethammer and Prof. Colin Raffel. I am a member of the Royster Society of Fellows and was supported by its Dissertation Completion Fellowship. I have spent time at Google, Nvidia and Siemens Healthineers during my Ph.D. Before my Ph.D., I received my master’s degree on Imaging Science from Rochester Institute of Technology advised by Prof. Nathan Cahill on remote sensing image analysis and image registration. I received my bachelor’s degree from Department of Physics at Xi’an Jiaotong University, where I did research at Quantum Optics Lab with Prof. Pei Zhang.

My research focuses on improving data efficiency, robustness and generalization of deep neural networks, including topics like self/semi-supervised learning, vision and language learning, domain generalization and compositional generalization.
