I am a postdoc at MIT Math. Before this I did a one-year postdoc at CMU hosted by Prof. Aayush Jain and Prof. Pravesh Kothari. I graduated from Harvard in 2022 advised by Prof. Madhu Sudan and was an undergrad at IIT Madras.
My research is focussed on complexity theory and algorithms, specifically the complexity of combinatorial optimization problems, sum of squares algorithms and high dimensional expanders.
