About Me

I am currently an Applied Scientist at AWS AI. Feel free to contact me if you are interested in an Intern job at Amazon.

I completed my Ph.D. at the Department of Computer Science at the University of North Carolina at Chapel Hill, advised by Professor Junier Oliva. Thanks to the committee members: Dr. Marc Niethammer, Dr. Mohit Bansal, Dr. Colin Raffel and Dr. Shahriar Nirjon.

During my time at UNC, I'm a member of LUPALAB led by Dr. Junier Oliva. Before joining LUPALAB, I worked with Dr. Dinggang Shen in IDEALAB.

Before coming to UNC, I received my B.Sc. degree in Biomedical Engineering from Beihang University in 2016. I worked closely with Dr. Yan Xu during my undergraduate period.

Research Interests

My research interests include machine learning, generative modeling, reinforcement learning, exchangeable data modeling, meta learning, adversarial learning, natural language processing, etc. Specifically, I focus on models that interact with its environment and user and reason with uncertainty.

Generative Models: capture distributions for tabular data, images, languages, sets, etc

Model-based Reinforcement Learning: leverage generative models for better decision making

Active Feature Acquisition: acquire the most informative features for cost-sensitive problems

Robustness: build robust model against adversarial attacks and out-of-distribution inputs
