Research Interest
My current research focus is healthcare informatics - primarily, applications of machine learning and AI to real-world and big health data. I am particulary interested in applying AI/ML for interpretable and scalable models for population and precision health. Some of my core research interests are temporal data mining, data assimilation/augmentation, and multi-source fusion. My Ph.D. thesis, advised by Dr. Naren Ramakrishnan, was on multivariate temporal data mining in the presence of weakly correlated signals towards public health surveillance
