About Me

I am a final-year Ph.D. student at VIU Lab, Johns Hopkins University. I obtained my bachelor's degree from UIUC CS in 2020. During my undergrad at UIUC, I have conducted research at UIUC-IFP Group. I am/was an intern at Netflix Eyeline Studios (Scanline VFX) (2024), Epic Games (2023), Adobe (2022-2023), Microsoft (2021).
I do research for digital content creation. I develop novel technologies related to vision + graphics. I am open to coffee chat :). Send me an email if you are interested.
