I'm a final year student at IIIT Kottayam, broadly interested in algorithms, combinatorics, graph theory, and game theory. My current research focuses on computational social choice and graph theory. At IMSc, I work on game theory problems like fair allocation and coalition games. At LIS, I work on identification problems in graphs. Outside of research, I run an independent digital zine about my thoughts and experiences.
