My research interests mainly focus on Software Engineering for/with AI, Trustworthy AI, and Data Science. I received WWW 2019 Best Paper Award, ACM SIGSOFT Distinguished Paper Award, ASE 2023 Distinguished PC Member Award, and ICSE 2025 Distinguished Reviewer Award.

📍Openings: I am recruiting Post-docs, PhD, Master’s, and undergraduate students. I welcome self-motivated students with strong backgrounds in AI and/or Software Engineering. Both on-site and remote research internships are available. If you are interested in joining my group, please send me your CV via email.
