I am a first year MSCS student at the University of Maryland, College Park. My research is focused on multimodal foundation models, specifically large audio/speech models. I am particularly interested in improving the reasoning capabilities, trustworthiness and safety of these models. At UMD, I am part of the GAMMA Lab and PIRL Lab. I am advised by Prof. Dinesh Manocha and Prof. Ramani Duraiswami.

Prior to joining UMD, I spent a year and a half working at the Indian Institute of Science, as a part of LEAP Lab, where I worked on the benchmarking and uncertainty estimation of large audio language models. In 2024, I graduated with a bachelors degree in Computer Science from PES University, Bangalore.

For research collaborations, feel free to reach out to me via email.
