Hello! Welcome to my page.
I am currently working as a postdoctoral research associate with Prof. Subramanian Ramamoorthy at Institute of Perception, Action and Behaviour in School of Informatics and College of Science and Engineering at the University of Edinburgh. I am developing computational methods for generative modeling of human behavior towards building AI for Assistive Autonomy. Previously, I worked as postdoctoral research associate at the University of Manchester where I worked on human-in-the-loop modeling for multi-objective Bayesian optimization under the supervision of Prof. Samuel Kaski. Prior to that, I earned my Ph.D. from the Department of Computer Science at Indian Institute of Technology, Hyderabad, under the supervision of Dr P.K Srijith and Dr. Maunendra Sankar Desakar where I investigated towards modeling of event sequences using temporal point processes and neural networks. You can find my CV here for more details.
My research focuses on developing algorithms for machine learning and demonstrating the practical impact of these innovations in diverse applications such as event sequences, time-series analysis, natural language processing, social network analysis, and scientific discovery. I have worked on a variety of methods like Bayesian techniques, deep learning, stochastic processes and graph neural networks. My research interests and experiences include multi-objective optimization, Human-AI collaboration, survival analysis, temporal point processes, sequential modeling and spatio-temporal modeling. I am interested in working in interdisciplinary research areas as well, where I can utilize my research knowledge of machine learning models for solving real-world challenges.
