I am a co-founding partner of Interpretable AI, which delivers interpretable methods and solutions for machine learning and artificial intelligence. I obtained my PhD 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, valuing both performance and interpretability.
Alongside my research, I am a contributor to various open-source projects. I was 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 have also contributed 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.
