I am a fifth-year PhD student in the Computer Science Department at the University of North Carolina at Chapel Hill, advised by Mohit Bansal. At UNC, I am part of the MURGe-Lab and the broader UNC-NLP group. My research is supported by the Apple Scholars in AI/ML PhD fellowship.

My research focuses on Natural Language Processing and Machine Learning. In particular, I work on developing methods to evaluate and strengthen reasoning in Large Language Models (LLMs). I seek to develop methods that enable LLMs to identify and rectify issues in its reasoning, improve alignment, as well as to enhance the understanding of the reasoning process. I also explore practical applications of LLM reasoning in domains such as planning and coding.

During my PhD, I have been fortunate to intern at several prominent groups, including Google DeepMind with Pete Shaw, Kenton Lee, and Mandar Joshi (Summer 2025); FAIR (Meta) with Jason Weston and Maryam Fazel-Zarandi (Summer 2024); the Allen Institute for AI (AI2) with Tushar Khot, Ashish Sabharwal, and Peter Clark (Summer 2023); and Adobe Research in 2022.
