Hi, I’m Qianyi (pronounced like “Channing”). I am a third-year PhD student in the Department of Management Science and Engineering at the School of Economics and Management, Tsinghua University. I’m fortunate to be advised by Prof. Bo Li. Prior to my doctoral studies, I earned a Bachelor of Engineering degree from Tsinghua University, majoring in Industrial Engineering with a minor in Data Science and Engineering.

My research interests span causal inference and machine learning, with a particular focus on addressing practical challenges involving complex treatments. Specifically, I am interested in:

  • Experimental design and estimation techniques under network interference
  • Incentive-aware machine learning involving algorithms acting as treatments

My goal is to develop effective, scalable, sample-efficient, and easy-to-implement statistical methodologies to address practical challenges.
