About
I am a PhD student advised by Dr. Aniket Bera at IDEAS Lab, Purdue University, Department of CS. 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 physical systems 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, under the supervision of Dr. Tianyi Zhang .
During the summer of 2022, I interned at ResconAI, a JHU Startup. I had the privilege of working with Dr. Suhas Eswarappa Prameela and Dr. Burigede Liu . My primary work was to explore Neural Operator based architectures to solve Partial Differential Equations.
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 Linkin Park.
