I am a postdoctoral researcher at the Simons Institute at UC Berkeley, where I am part of the the Foundations of Data Science Institute (FODSI). I am broadly interested in machine learning, optimization, signal processing, and control, especially 1) online learning and learning theory, and 2) integrating machine learning with signal processing and control.

Before moving to Berkeley I was a PhD student in the Computing and Mathematical Sciences (CMS) department at Caltech, where I was extremely fortunate to be advised by Babak Hassibi. My PhD work was supported by a National Science Foundation Graduate Research Fellowship and an Amazon AI4Science Fellowship. My thesis was awarded the Bhansali Family Doctoral Prize in Computer Science, which is awarded by the CMS department to a single outstanding dissertation in computer science each year.

I'm on the 2022-2023 academic job market! Here is my CV and research statement.
