Biography

Dawei Cheng (程大伟) is currently an associate professor appointed at Department of Computer Science and Technology of Tongji University (同济大学), Shanghai, China. I serve as dean assistant of Collaborative Innovation Center of Internet Finance Safety, and guest Ph.D. supervisor at the University of Technology Sydney, Australia. I specialize in data mining, machine learning, deep learning and reinforcement learning. Now I mainly focus on big data in finance, deep learning in complex financial networks and big data analysis.

Prior to now, I was a postdoctoral associate at Center for Brain-like Computing and Machine Intelligence (BCMI), Shanghai Jiao Tong University (SJTU) , China. Before that, I obtained my Ph.D degree in computer science from Shanghai Jiao Tong University, supervised by Prof. Liqing Zhang and bachelor degree from Nanjing University of Aeronautics and Astronautics in China.
