Huayao Wu

I am currently a Tenure-Track Assistant Professor (准聘助理教授/博导) at the School of Computer Science, Nanjing University. I am also a member of the GIST group. My research focuses on software testing. I am interested in creating automated and intelligent techniques and tools to solve software testing problems.

I received my PhD degree from Nanjing University (NJU) in 2018, under the supervision of Prof. Changhai Nie, and the BS degree from Southeast University (SEU). I have been a visiting student at CREST of University College London (UCL), from 2016 to 2017. My supervisors in CREST are Prof. Justyna Petke and Prof. Mark Harman.

Our research projects typically focus on the automated generation of challenging test inputs that trigger diverse and suspicious behaviours of software systems 🤯. The solutions we devise usually involve a blend of combinatorial, geometry, search based, and fault based techniques. Recently, we are specifically pursuing testing and quality assurance for web services (📑 ICSE'22, TSE'23, ISSTA'25) and AI-driven systems (📑 ASE'23, ISSRE'24, Internetware'25).

🔖 We are constantly looking out for motivated PhD, master, and undergraduate students who whould like to work on topics related to intelligent software testing. Feel free to contact me via email :-)
