I am a PhD student at IDEAS lab. My research interests are to work on optimization of AI models for scientific Machine learning, the integration of physics informed AI models into computer graphics and robotics to accelerate their performance. Broadly put, I want to answer to important research questions - "How can AI be used in conjunction with classical methods to model physics?" and "How can principles of mechanics and physics be modelled in graphics and robotics?"

I am currently exploring physics informed neural architectures and stochastic approaches to model fluid behavior in a geometry agnostic and discretization agnostic manner to achieve atleast 5x the speedup compared to methods such as MPM, SPH and FEM.

I have done multi-disciplinary research projects with various research groups. More recently I have worked on fairness analysis of Large pretrained Language Models at Purdue University, as part of my Master’s research, with Dr. Tianyi Zhang. I have also worked at ResconAI, an MIT startup, to design Neural Operator based architectures to solve Partial Differential Equations.

I am an ardent fan of sci-fi and fantasy genre, with an affinity towards Space-Operas. I love Empire Strikes Back and Revenge of the Sith. My favorite books for 2024 are Dune (Frank Herbert), The Three Body Problem (Cixin Liu), Physics of the Impossible (Michio Kaku), Critique of Pure Reason (Immanuel Kent) and First Man (James R. Hansen).

I love Hiking and exploring the countryside. I'm a space enthusiast and follow Neil DeGrasse Tyson. I collect comics specifically DC Comics (New 52) and Franco-Belgian BD. I listen to a lot of Rock and Metal and am a huge fan of Guns N' Roses, Michael Jackson and Metallica.
