Curriculum Vitae

About

I received a Ph.D. degree from William & Mary in 2020, under the supervision of Dr. Xu Liu, an M.S. degree from Institute of Computing Technology, Chinese Academy of Sciences in 2016, and a B.E. degree from Yunnan University in 2013. My research interests broadly lie in programming languages, program analysis, high-performance/parallel computing as well as software engineering, with an emphasis on providing tools support for analyzing and optimizing software inefficiencies.

Multiple openings are available for self-motivated M.S. and Ph.D. students. Feel free to ping me with your resume, transcript, and anything else that could be a plus for your application!
