Hi there👋. I’m Zhixi Chen (Sometimes I choose Chih-Hsi Chen as my name, my Chinese name is 陈治希 or 陳治希), you can just call me Humphrey, or Zhixi. Currently, I am an incoming Ph.D. student in the College of Computing and Data Science (CCDS) at Nanyang Technological University, Singapore. Previously, I obtained my M.Sc. (Data Science) Degree in the College of Computing and Data Science (CCDS) at Nanyang Technological University, Singapore, Supervised by Dr. Yinan Zhang and Dr. Zhiqi Shen. Before that, I earned my B.Eng. in Software Engineering degree (Financial Technology Track) with Minor in Finance in Software College, Northeastern University, Shenyang, Liaoning, China.
My research interest includes but not limited to,
- Large Language Models and its application to business and finance
- Quantitative Finance with Machine Learning / Deep Learning Methods
