About

Starting June 2021, I will a Research Scientist at Mitsubishi Electric Research Laboratory (MERL) in Cambridge, MA. I received my Ph.D. in electrical engineering from Boston University in 2020, during which I was supported by a Draper Fellowship. Following my PhD, I was a Postdoctoral Researcher in the Computational Imaging Lab at Stanford University.

My research lies at the intersection of optics, electronics, signal processing, mathematical modeling, and computer vision. So far, my work has focused on expanding the capabilities of single-photon lidar systems, from increasing acquisition speed, temporal resolution, and robustness to ambient light to seeing around corners.
