Dr. Ritwik Banerjee specializes in natural language processing (NLP), and applications of machine learning (ML). Currently, he is a Research Assistant Professor of Computer Science at Stony Brook University, and is affiliated with the Institute for AI-Driven Discovery and Innovation. For his work in biomedical language processing, he also served the Department of Emergency Medicine (Stony Brook School of Medicine) as a research faculty.

Dr. Banerjee was awarded his Doctor of Philosophy (PhD) in computer science from Stony Brook University in December 2015, advised by Yejin Choi and co-advised by I. V. Ramakrishnan. As part of his doctoral research, he was associated with dMetrics Inc. – an AI and NLP company based in New York – as a Research Engineer. Additionally, he has also been a visiting scholar at the Indian Institute of Technology, Kharagpur. Prior to his doctorate, he was a core member of the research team in two AI-based SaaS startups in India. He earned his Master of Science (M.Sc.) degree in Computer Science, and the Bachelor of Science (B.Sc.) degree in Mathematics and Computer Science, both from the Chennai Mathematical Institute, India.

Details of his current and past work can be found in the research and publication pages.
