Dr. Chattopadhyay’s research focuses on the theory of unsupervised machine learning, and the interplay of stochastic processes and formal language theory, in exploring the mathematical underpinnings of the question of inferring causality from data. His most visible contributions include the algorithms for data smashing, inverse Gillespie inference, and nonparametric nonlinear and zero-knowledge implementations of Granger causal analysis, that have crucial implications for biomedical informatics, data enabled discovery in biomedicine, and personalized precision healthcare. His current work focusses on algorithmic prediction of zoonotic emergence, analyzing massive clinical databases of disparate variables to distill patterns indicative of hitherto unknown etiologies, unsupervised inference of complex spatio-temporal datasets spanning biology, medicine and social interactions.
