Research in software engineering, AI, LLMs, mobile systems, HCI, accessibility, and security

I am a professor in the Department of Computer Science at School of CIT, Technical University of Munich, Heilbronn Campus. I obtained my PhD from Nanyang Technological University (NTU), Singapore, and my research spans software engineering, AI, deep learning, natural language processing, and human-computer interaction. My first name, "Chunyang," sounds like "train young," which is exactly my job in the university.

Research focus

Specifically, I apply AI, machine learning, NLP, and lightweight program analysis techniques in the following directions:
