Quality Lab



Chao Peng (彭péng, 超chāo)

I am a Tech Expert / Senior Researcher at ByteDance (字节跳动) working on software quality assurance. I received my PhD degree from Laboratory for Foundations of Computer Science (LFCS), The University of Edinburgh under supervision of Dr. Ajitha Rajan.

At ByteDance, I am on the Quality Lab team. My research interest lies in the area of software testing, maintenance and quality assurance, and the synergy with machine learning and compiler techniques. I am also responsible for lab-wide research development and academic cooperation.

I am passionate about building practical software testing, analysis, and debugging systems to predict, detect, diagnose, and fix bugs for all kinds of software systems.

Outside of work, I enjoy going to the gym.
