Short Bios

I am currently a Research Assistant Professor in Nanjing University. Before that, I received my PhD degree from Shanghai Jiao Tong University in June 2024, master degree from Beihang University in March 2018 and bachelor degree from Southeast University in June 2015. I am very grateful for learning so much from my PhD advisor, Shizhen Zhao. Besides, I was a Research and Development Engineer (special offer winner) in Baidu's search infrastructure team from April 2018 to May 2019,

Research Interests

My research interests include optimizing data center networks (including topology, routing and RDMA, etc.), large-scale network simulator and network bottleneck analysis. Besides, I am committed to close the gap between theory and the real world.
