About

I’m a final-year PhD student at the Department of Computer and Information Science, University of Pennsylvania, advised by Prof. Dan Roth.

My research spans natural language processing and broader artificial intelligence. Recently, I’m particularly interested in studying different types of conflicts that emerge in modern AI systems, including:

• Hallucinations, factuality and alignment — model generations that are non-factual, toxic, or unsubstantiated/contradictory to the contexts [Long-Context Hallucination, DeeptraceReward]
• Retrieval, knowledge conflicts, and reasoning — How can LLMs reason through conflicting knowledge from different sources (contextual/parametric knowledge)? [ConflictScore, Conflicting QA]
• Perspectives and biases — conflicts across different perspectives and opinions [Multi-Perspective Search, MultiOpEd, News Framing]

Some of my other ongoing projects include:

• Teaching LLMs to learn from failures/feedback
• Deepfake Video Detection
• Representation Learning for Authorship Representation

Some of my other past projects include:

• Open Source Project (Core Contributor) - Distilled Generative Text Embedding Model
• Framing Bias Detection
