About Me

I am a second year Ph.D. student in the Department of Computer Science @ UVa. My advisor is Prof. Yangfeng Ji. My research interests lie in Natural Language Processing, Deep Learning, and Interpretable Machine Learning. I received my B.E. from Nanjing University of Aeronautics and Astronautics (NUAA) in 2015, and M.E. from University of Science and Technology of China (USTC) in 2018.
