马兰霁弘 Lanjihong Ma Ph.D. candidate, LAMDA Group School of Artificial Intelligence Nanjing University, Nanjing 210023, China Supervisor: Professor Zhi-Hua Zhou

Biography

Currently I am a second year Ph.D. candidate of School of Artificial Intelligence in Nanjing University and a member of LAMDA Group, led by professor Zhi-Hua Zhou.

I got my B.Sc. degree in Energy and Power Engineering in June 2017 from School of Aerospace Engineering of Tsinghua University. Then I got my M.Sc. degree in Mechanical Engineering in January 2019 from Jacobs School of Engineering of University of California, San Diego (UCSD). In the same year, I was admitted to pursue Ph.D. degree in Nanjing University by passing the entrance examination.
