About Me

I am a postdoctoral researcher at MIT, where I work with Ali Jadbabaie and Suvrit Sra on algorithms for optimization in theoretical computer science and machine learning. I completed my Ph.D. in 2023 from the University of Washington, Seattle, mentored by Yin Tat Lee. [dissertation]

During my Ph.D., I interned with Jelena Diakonikolas at the University of Wisconsin, Madison, with Di Wang and Zhe Feng (Google Market Algorithms), and with Richard Q. Zhang and David P. Woodruff (Google DeepMind Vizier).

Before starting optimization research, I studied Electronics/Electrical Engineering, with research on rapid diagnostic tests for malaria, and spent some time in industry as a signal processing engineer working on pulse oximeters and bluetooth speakers.

This paper appeared in STOC 2020. However, after the publication, we found an error in the analysis (see arxiv), and we are trying to fix it.
