GREETINGS! WELCOME TO MY HOMEPAGE. 

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

• • Matrix Factorization and Efficient Optimization Algorithms

  • Large-scale Feature Selection, Clustering, and Data Analytics

  • Learning to Hash, Information Retrieval, and Heterogeneous Data Fusion

  • Sparse and Low-rank Modeling, Subspace Learning, and Regression Analysis

  • Mechanism of Human Collective Learning and its Application to Machine Learning
