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).
