Subhro Das is a Staff Research Scientist and Research Manager at the MIT-IBM AI Lab, IBM Research, Cambridge MA. As a Research Affiliate at MIT and Principal Investigator (PI), he works on developing novel deep learning algorithms in collaboration with MIT researchers. He is an IBM Master Inventor and has filed 25+ patents in priority areas of machine learning and dynamical systems. His research papers are published in top top AI/ML and signal processing venues, including ICML, NeurIPS, ICLR, AAAI, AISTATS, EACL, IEEE Transactions on Signal Processing and ICASSP.

His research interests are broadly in the areas of Representation Learning, Generative AI, Foundation Models, Trustworthy Machine Learning, Large Language Models, Reinforcement Learning, Dynamical Systems and ML Optimization methods. At the MIT-IBM AI Lab, his research work focuses on uncertainty quantification and human-centric system design for Large Language Models; deep learning for time-series; and, robust, accelerated & distributed optimization methods. He led the Future of Work initiative within IBM Research, studying the impact of AI on labor market and developing AI-driven recommendation frameworks for skills and talent management. Previously, at the IBM T.J. Watson Research Center in New York, he worked on developing signal processing and machine learning based predictive algorithms for a broad variety of biomedical and healthcare applications.

He received MS and PhD degrees in Electrical and Computer Engineering from Carnegie Mellon University in 2014 and 2016, respectively. His dissertation research was in distributed filtering and prediction of time-varying random fields and he was advised by Prof. José M. F. Moura. He completed his Bachelors (B.Tech.) degree in Electronics & Electrical Communication Engineering from Indian Institute of Technology Kharagpur in 2011. During the summers of 2009, 2010 and 2015, he interned at Ulm University (Germany), Gwangju Institute of Science & Technology (South Korea), and, Bosch Research (Palo Alto, CA), respectively.
