I am a PhD Student in Yardi School of Artificial Intelligence at Indian Institute of Technology Delhi. I work at the intersection of Large Language Models and Planning under the guidance of Prof Mausam and Dr Manish Gupta (Microsoft). My research focuses on developing architectures and benchmarks to enhance the capabilities of LLMs in planning-intensive tasks and complex decision-making scenarios.

I am always open to discussions. Please feel free to reach out!
