I am a fifth-year Ph.D. student at the Operations Research Center at MIT, advised by Dimitris Bertsimas. I am broadly interested in data-driven optimization with applications in urban operations, and currently work with Julia Yan on the optimization of large-scale public transit networks.

In summer 2018, I was hosted by Ross Anderson and Ondrej Sykora under Jon Orwant in the Operations Research group at Google. While there, we worked with Christian Tjandra and Joey Huchette on solving optimization problems over trained neural networks, with applications across genomics and deep reinforcement learning.

I've also spent a summer with Sidhant Misra and Line Roald in LANL under the Advanced Network Science Initiative. We developed machine learning techniques for solving parametric optimization problems efficiently, and had the good company of Carleton Coffrin and Kaarthik Sundar in developing research software for power systems.

Prior to MIT, I graduated from NUS with a B.Eng. in Industrial and Systems Engineering, and did research with Jin Qi under the Decision Science (now Analytics & Operations) department and Yossiri Adulyasak under the Future Urban Mobility Lab, under the mentorship of Melvyn Sim and Patrick Jaillet.
