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 with a CPI of 9.07, working under the guidance of Prof. Anirban Dasgupta. My research focuses on Graph Neural Networks, particularly addressing challenges in expressivity and inference optimization.
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) with a CGPA of 8.42, and my B.Sc in Mathematics from Presidency University with a CGPA of 6.95.
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.
