Specializing in Graph Neural Networks, with focus on expressivity and inference optimization
About Me
I am currently pursuing my PhD in Computer Science and Engineering at IIT Gandhinagar, working under the guidance of Prof. Anirban Dasgupta. My research focuses on Graph Neural Networks, particularly addressing challenges in expressivity and inference optimization.
During summer 2026, I am interning at IBM Research - Bangalore as a Research Intern in the Platforms in AI team, working on scalability and optimization of AI systems.
Prior to my PhD, I completed my M.Sc in Mathematics and Computing with a major in Computer Science from the Indian Association for the Cultivation of Science (IACS), and my B.Sc in Mathematics from Presidency University.
My current research involves developing novel approaches to improve GNN expressivity beyond the Weisfeiler-Leman hierarchy and creating efficient inference methods through graph coarsening techniques. I am particularly interested in applications of GNNs to weather prediction, social network analysis, and knowledge graph construction.
