I am currently a postdoctoral researcher at the University of Pennsylvania (UPenn), working with Prof. Christos Davatzikos. I obtained my Ph.D. in computer science and technology from the Tsinghua-Berkeley Shenzhen Institute (TBSI), Tsinghua University in 2020, under the supervision of Prof. Wenwu Zhu. I have been a visiting scholar at the University of California, Berkeley (UCB) from 2019 to 2020. I received a bachelor's degree in electronics and information engineering and a master's degree in information and communication engineering from the Dalian University of Technology (DUT) in 2013 and 2016, respectively. 

My research interests span pattern recognition and machine learning with a special focus on sparse learning, matrix factorization, and their applications to multimedia and data processing. Recently, my research topics include:
