Xu Zhang
Welcome to my homepage!
I am Xu Zhang, an assistant professor at the School of Artificial Intelligence, Xidian University. Previously, I was a Postdoc at the State Key Laboratory of Scientific and Engineering Computing, Academy of Mathematics and Systems Science, Chinese Academy of Sciences from 2021 to 2023. I received my Ph.D. and B.S. degrees in electronics engineering from the School of Information and Electronics, Beijing Institute of Technology, Beijing, China, in 2021 and 2015, respectively. I was a Visiting Student with the Ming Hsieh Department of Electrical Engineering, University of Southern California, Los Angeles, CA, USA, from 2018 to 2019. My research interests include federated learning, distributed optimization, and sparse learning.
