About me

I am a von Kármán Instructor at Caltech in the Computing + Mathematical Sciences department, hosted by Venkat Chandrasekaran. I also work with Katie Bouman and the Computational Cameras group. I will be joining UCLA Statistics and Data Science as a tenure-track Assistant Professor in July 2024. I completed my PhD from Rice University in Computational and Applied Mathematics under the supervision of Paul Hand and was an NSF Graduate Research Fellow. I received my undergraduate degree in Mathematics from Swarthmore College. 

My research interests lie in the mathematics of data science, inverse problems, machine learning, and optimization. Much of my work concerns solving signal recovery problems with approaches inspired by deep learning and uses tools from high dimensional probability, random matrix theory, and optimization to develop provable recovery guarantees.

Family: my wife, Wani, is in developmental psychology. We welcomed our first daughter, Gemma, in May of 2023.
