Huayao Wu

I am currently a tenure-track Assistant Professor 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.

🔖 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 :-)
