Sangwon Hyun’s CV

I am a post-doc researcher at the University of Adelaide and a member of the Centre for Research on Engineering Software Technology (CREST). I got a Ph.D. from the Software Engineering Lab (SELab) at Korea Advanced Institute of Science and Technology (KAIST), advised by Prof. Doo-Hwan Bae. I have a few experiences in leading research projects to analyze the reliability or safety of complex systems, such as platooning vehicles, swarming drones, and edge cloud-based systems. In addition, I have wide research experiences ranging from surveying, development, experimental dataset generation, and empirical analysis for complex systems. Currently, I concentrate on proposing an effective testing approach for Large-Language Models (LLMs) and applying digital twin-based testing techniques on autonomous and safety-critical systems.
