Hello! I'm a PhD student at Pennsylvania State University, specializing in the Informatics track with a focus on Data Science & Artificial Intelligence. I am advised by Prof. Dongwon Lee and a part of the PIKE research group. I am also a Visiting Scholar at New York University in Prof. He He's group.

My research focuses on machine-generated text detection, authorship attribution, obfuscation, and watermarking approaches for Large Language Models (LLMs). I am also interested in the evaluation of LLM-generated texts and what might or might not make them "human-like". I hope to work further on leveraging psycholinguistic theory for Natural Language Processing (NLP) applications and find ways in which models can directly learn from human cognitive processes.

During my PhD, I have been a research intern at Google, Samsung Research America, and Cadence Design Systems, helping build Reinforcement Learning (RL), NLP, and Machine Learning (ML) solutions for different applications such as dialog-based recommenders, voice assistants, and custom hardware design layouts, respectively.
