Prof. Shi Pu is an Assistant Professor at the School of Data Science, The Chinese University of Hong Kong, Shenzhen. Prof. Pu earned his Ph.D. in Systems Engineering from the University of Virginia in 2016, and joined us from Boston University where he held a postdoctoral associate position. From 2016 to 2018, he conducted postdoctoral research at the University of Florida and then Arizona State University. His research interests mainly lie in distributed optimization, learning and control within networked multi-agent systems. He has published in top journals such as Operations Research, Mathematical Programming and IEEE Transactions on Automatic Control.
