Short bio

Xiyue Zhang (Pronounced: Shee-you-eh Jahng - or, feel free to call me Ciel/Cielle) is a Lecturer (Assistant Professor) in the School of Computer Science at the University of Bristol. Her current research mainly focuses on trustworthy deep learning, formal modelling and verification. Previously, she was a postdoctoral research associate working with Prof. Marta Kwiatkowska in the Department of Computer Science at the University of Oxford (2022-2024). She received her Ph.D. (2022) in Applied Mathematics, advised by Prof. Meng Sun, and her B.Sc. (2017) in Information and Computing Science from the Peking University.

Recruitment

I am looking for motivated Ph.D. students with a strong interest in formal verification or empirical analysis of data-driven models and systems. Ideal candidates will have a background in computer science or a closely related field. Scholarships are available for both home and international students, including those at the University-level, Faculty-level, CDTs, CSC, and others. Feel free to email me if you’d like to discuss further!
