About Me (CV)

I am a PhD student at UPenn. My advisor is Dr. René Vidal.

I work on optimization, machine learning, and computer vision.

Topics and keywords of interest to me include

[2022 - ]: block coordinate descent (1 2 3) and related algorithms (4 5)
[2022 - ]: lifelong/continual learning (1 2)
[2021 - ]: geometric computer vision (1 2 3 4 5 6)
