Hello! I am a PhD candidate in Computer Science at Arizona State University (ASU), advised by Prof. Huan Liu. My research lies at the intersection of data mining, computational social science, AI, and NLP. I am particularly interested in understanding and mitigating online harms, such as disinformation, echo chambers, and conspiracies, and in leveraging and evaluating large language models for the benefit of science and well-being. I also work closely and am advised by Prof. Kristina Lerman and Prof. H. Russell Bernard.

Research Interests

• Data Mining: Developing advanced algorithms to collect, analyze, and model big data, aiming to provide practical insights to real-world applications and decision making.
• Computational Social Science: Leveraging computational methods and statistical models to interpret social phenomena and address social problems.
• AI for Good: Advancing applied ML, AI, and Human-AI collaboration to solve real-world problems and promote well-being; AI for science, AI evaluation, Large Language Model application.
