Portrait of Arpita Gang
Arpita received her B.Tech (Bachelors’ degree) in electronics and communication engineering from NIT Silchar (silver medalist), and M.Tech (Masters’) from IIIT Delhi in India. She then worked as a research assistant at IIIT Delhi for a year. Following this, she completed her Ph.D. in electrical and computer engineering from Rutgers University, New Jersey in 2022. Her research interests are in distributed optimization and machine learning. She joined Visa Research in June 2022 as a Staff Machine Learning Scientist where she is a part of the AI Prototyping team.
