I completed my PhD in Stanford's Electrical Engineering department under the supervision of Mohsen Bayati, and spent a year as a Herman Goldstine postdoctoral fellow at IBM Research. Previously, I graduated summa cum laude from Harvard in 2012 with a A.M. in physics, and a A.B. in physics and mathematics.

My research focuses on developing novel machine learning algorithms for data-driven decision-making, with applications to healthcare operations, social good, and revenue management. I design methods for sequential decision-making (bandits, reinforcement learning, active learning) and leveraging auxiliary data sources (transfer learning, meta-learning). Recent applications include deploying a targeted COVID-19 testing strategy in Greece [1], speeding up clinical trials by leveraging surrogate outcomes [2], meta dynamic pricing across many related products [3], and predictive analytics with small data (for supervised learning [4] and unsupervised learning of word embeddings [5]). I'm also passionate about using large-scale, novel data sources to inform policy around impactful societal problems (e.g., sex trafficking on the deep web [6], illegal fishing in seafood supply chains [7], labor and environmental violations in responsible sourcing [8]). Finally, I enjoy thinking about the human-AI interface (e.g., human-in-the-loop analytics [9], improving human decision-making with interpretable reinforcement learning [10]). My work has received several recognitions, including the Pierskalla Award for the best paper in healthcare (2016, 2019), as well as first place in the George Nicholson and MSOM student paper competitions (2016).

I primarily teach OIDD 321: Introduction to Management Science, for which I received the Wharton Teaching Excellence Award in 2019 and 2020. I also teach a PhD class OIDD 941 on topics in data-driven decision-making. I currently serve as an Associate Editor for M&SOM and Area Chair for NeurIPS 2021.
