PhD Student, Columbia Business School
Decision, Risk, and Operations
I am a PhD student at Columbia Business School in the Decision, Risk, and Operations division.
I am advised by Jing Dong
and Hongseok Namkoong.
My research is on model-based machine learning for developing new
computational approaches for large-scale problems in OR/MS. Some tools I use in my research are,
- Differentiable Simulation
- Deep Reinforcement Learning + Optimal Control
- Stochastic Modeling (e.g. fluid and diffusion models)
In particular, I am interested in applications in adaptive experimentation and scheduling in queuing networks and discrete-event systems. I've also done research in mechanism design.
I worked as an ML engineer intern at Instacart in Spring 2023. I am a research intern at Netflix for Summer 2024.
