I'm a PhD student in computer science at Princeton University, advised by Ryan P. Adams.
I'm broadly interested in deep learning, probabilistic modelling, stochastic estimation, and numerical methods. My main area of focus is developing machine learning methods to accelerate and automate numerical modeling, simulation, and design. Recent work has focussed on randomized gradient estimation (trading off bias, variance and computation) for optimization problems in ML and engineering, and ML methods for accelerating finite element analysis and PDE-constrained optimization.
This year I'm organizing a NeurIPS workshop on machine learning for engineering: ML4Eng.
I spent two fun summers at Google: at Google Brain in Zurich, working on AutoML for generative models with Sylvain Gelly, Olivier Teytaud, and Karol Kurach; and with the speech recognition team in New York, working on transfer learning with Pedro Moreno.
Previously, I received my Master's from Princeton advised by Han Liu. I did my B.Eng at the University of Canterbury in New Zealand, where I worked with Geoff Chase on signal processing for ventilators in the intensive care unit.
