About Me

I am a fifth-year PhD candidate in Operations Research at Tepper School of Business, Carnegie Mellon University. I am joining Cornell Tech as an Assistant Professor in ORIE starting July 2023, and I will spend one year at the Statistical Reinforcement Learning lab with Susan Murphy. My advisors are Prof. Sridhar Tayur and Prof. Andrew Li. I also work closely with Prof. Zachary Lipton and Prof. Alan Scheller-Wolf, and I am part of the ACMI lab. Prior to joining CMU, I received my BA degrees in Mathematics (with the Ann Kirsten Pokora Prize) and Economics from Smith College in May, 2017. I completed my first year of college at UCSD in June, 2014. I am originally from Hangzhou, China.

Research Interests

I am interested in efficient algorithms in precision medicine, and my work lies in the intersection of optimization, machine learning, and medicine. As the concept of precision medicine spreads, there is a growing need for developing better algorithms that
  • are sample efficient (i.e., require fewer samples to achieve the same accuracy level),
  • think beyond association (to identify the causation hidden in the data),
  • provide insights to medical practice.
  • Thus, I am particularly interested in applying optimization in causal inference to provide guidance for medical practice. My past research includes a variety of healthcare topics, ranging from opioid use disorder, and sickle cell disease, to liquid biopsy. My past theoretical work has focused on a) optimal policies for deconfounding, b) active sequential hypothesis testing, and c) constrained POMDP. A copy of my CV can be found here.

    I am passionate about tackling real-world medical problems. I am actively collaborating with the University of Pittsburgh Medical Center, and I welcome all collaboration opportunities.
