Abhishek Aich

I am a Researcher at NEC Laboratories, America. Before this, I received my Ph.D. from University of California, Riverside in 2023, under the supervision of Prof. Amit K. Roy-Chowdhury.

During my Ph.D. studies, I was extremely fortunate to have interned at NEC Laboratories, America (2022), Mitsubishi Electric Research Laboratories (2021) and UII, America (2020).

Research opportunities: I am happy to collaborate on projects involving (not limited to) vision-language models, open-vocab perception, efficient transformers, and dynamic networks. If you are interested, please send me an email.
