I received my second Ph.D. degree at College of Information Sciences and Technology, Pennsylvania State University in 2022, supervised by Prof. Dongwon Lee. I received a Ph.D. degree in Computer Applied Technology at School of Computer and Control Engineering, University of Chinese Academy Sciences in 2018, supervised by Prof. Yong Shi and Prof. Philip S. Yu. Before that, I received my Bachelor degree in Software Engineering from Beijing Institute of Technology in June, 2013.

Research Interest

• AI in Cybersecurity: misinformation detection, fraud detection

• Healthcare: rare disease detection from EHR data

• Multi-modal: cross-modal retrieval, multi-modal embedding

FAQ (if you're interested)

1. How did you get into college at age 14?
   Short version: I was admitted to the Experimental Class for Exceptionally Gifted Children in Beijing No. 8 High School when I was 10 years old (acceptance rate<2%). Here's the introduction page (in Chinese). After 4 years of study, I went to college at age 14.
   Long version: See Section 6.1 in "Beijing Model of Gifted Education and Talent Development".
2. Why do you pursue another PhD degree?
   Because there is still a lot for me to learn and improve when I was graduated. And I want to embrace more possibilities in life.
