I am a final-year PhD candidate in Operations Research at Cornell University, where I am fortunate to be advised by David Williamson. I received my undergraduate degree from the University of Waterloo in 2018, majoring in Computer Science and Combinatorics & Optimization.
My research interests lie in the union of online decision-making, stochastic optimization, and approximation algorithms. A focus of my recent research has been on advice-augmented algorithms, which use some advice or prediction (e.g. from historical data, forecasts, or expert advice), whose quality is unknown. I aim to design algorithms that perform well when the quality is high, yet remain robust in their performance even when the quality is low.
My research has been recognized with several awards, including an NSERC graduate fellowship, the 2023 Student Paper Prize awarded by the INFORMS Decision Analysis Society, and runner-up in the 2023 Student Paper Prize awarded by the INFORMS Optimization Society. Additionally, I was awarded the Best Flash Talk at the 2019 YinzOR Student Conference.
Previously, I have been a quantitative trading intern at Jane Street Capital, and a software engineering intern at Wish.
I am on the 2023-2024 academic job market!
