Tianyu Liu

I received the Ph.D. Degree from the School of EECS at Peking University, advised by Prof. Lingyang Song, and co-advised by Prof. Kaigui Bian and Prof. Boya Di. My research interests lie in federated learning, edge computing and reinforcement learning.

I received the Master's Degree from Peking University and the Bachelor's Degree from Zhejiang University. I was ever an intern at Microsoft, Baidu, and MSRA.
