I am a fourth-year doctoral candidate at the Operations Research Center at MIT advised by Dimitris Bertsimas. My primary research interest is the intersection of modern optimization with problems of statistics and machine learning, with the goal of developing new methods that significantly improve upon the state of the art.
Other interests include:
- robust and data-driven optimization,
- data analytics,
- decision-making under uncertainty.
Alongside my research, I am a contributor to various open-source projects. I am the lead developer of the OpenSolver add-in, which enables open-source optimization within Microsoft Excel (230,000+ downloads) and Google Sheets (13,000 weekly active users). I also contribute to the JuliaOpt suite of packages that enable optimization in the Julia programming language.
I have previously worked as an intern at Google, and I obtained my undergraduate degree (B.E. (Hons)) in Engineering Science from the University of Auckland in New Zealand.
