About Me

Currently I am a Marketing Gen AI Director at American Express Company, working on enterprise deep learning research and capability development. I obtained my Ph.D. degree from University of Michigan, Eletrical Engineering and Computer Science department, majoring in Control System, under the guidance of Professor Semyon M. Meerkov, in August 2021, and the B.S.E. degree from Harbin Institute of Technology (HIT), China, in 2016.

Research

My research interests include:

  • Natural Language Processing.
  • Stochastic System Analysis and Control.
  • Application of Probability Theory.
  • Optimization.
