Research Interest

My research focus is to connect software engineering research and AI research to improve software trustworthiness. Most recently, I am working on improving the trustworthiness of machine translation systems (ICSE 2022, ICSE 2020), programming language translation (ICLR 2022), Question answering software (ASE 2022), and the fairness of general ML classifiers (FSE 2022, FSE 2021, ICSE 2021). For an overview of the vision and literatue of software testing techniques for machine learning software, please refer to our survey on Machine Learning Testing (TSE 2020).

Before joining King's College London, I was a research fellow at University College London working with Professor Mark Harman and Professor Federica Sarro. I obtained my PhD degree in Computer Science from Peking University, China. My Phd advisors are Professor Lu Zhang and Professor Dan Hao.
