Research Interests
Changkun Ou received a Ph.D. in computer science at LMU Munich. His research focuses on intelligent human-in-the-loop systems and develops machine learning algorithms to exploit human preferential behavior, then support their decision-making process for the greater good. In context, he utilizes efficient and robust engineering practices to explore system design trade-offs that can bring actual impact to real users.Publications
