About

I am currently an AI Researcher at Amazon AWS AI. I obtained my Ph.D. in Computer Science from University of Notre Dame, advised by Nitesh Chawla, ACM/AAAI/IEEE Fellow. Before that, I earned my Master’s at New York University and Bachelor’s at Shandong University, both in Computer Science.

My research interests center around artificial intelligence, machine learning, and data science. My research aims to empower machines with knowledge (from data, models, and external sources) to positively influence real-world applications. Primarily, I focus on developing fundamental machine learning algorithms that are effective, efficient, and trustworthy, particularly on graphs. Recently, I focus on developing efficient LLMs and empowering LLMs with additional knowledge bases. My works contribute to various applications, including nutrition and food services, cybersecurity and privacy, chemistry and biology, and public health.
