Hi! I am a Ph.D. student in Computer Science and Engineering at University of Notre Dame, advised by Prof. Yanfang Ye. My research interests broadly lie in the application of retrieval-augmented large language models, recommender systems (e.g., graph-based collaborative filtering, click-through-rate prediction), graph representation learning over various domains (e.g., healthcare, mobile application promotion).

I have a very sweet tuxedo cat named Yaya. He was born in Chirstmas 2021, and was adopted by me in March 2023. I originally named him Toothless after Toothless in How to Train Your Dragon, which is one of my favorite animations. Since we usually talk to him in Mandarin, we decided to name him Yaya ('tooth' in Mandarin) instead.
My favorite artist is Taylor Swift, and I have been to her concerts in Shanghai (1989), Pittsburgh (Reputation), and Chicago (The Eras). I am also a fan of KPop, and would keep an eye on the latest KPop combacks of multiple girl groups. Feel free to reach out to me if you share similar interests with me!
