About

I am a second year Ph.D. student in the School of Computer Science at Georgia Tech under the guidance of Professor Kexin Rong. Prior to this, I collaborated with Stefan Savage, Geoffrey M. Voelker, and Ph.D. candidate Ariana Mirian at UC San Diego on various Internet measurement projects.

My current research interests revolve around data centric AI, databases, and multimodal models. Currently, I am working on automatically identifying and explaining “problematic” slices of image concept data.
