About
I am a PhD student in the Computing and Mathematical Sciences (CMS) department at Caltech, where I am extremely fortunate to be advised by Babak Hassibi.
I am broadly interested in machine learning, optimization, signal processing, and control, especially 1) online optimization and sequential decision-making under uncertainty, and
2) integrating ideas from machine learning with signal processing and control. Much of my PhD work has been supported by a National Science Foundation Graduate Research Fellowship and an Amazon AI4Science Fellowship.
In 2021 I was named a Rising Star in Data Science by the University of Chicago Center for Data and Computing.
I enjoy travelling, and have visited the following countries for conferences during my PhD: Australia (CDC 2017), Sweden (COLT 2018), Japan (AISTATS 2019), and Canada (NeurIPS 2019).
