Jaekwon Lee

I am an assistant professor in the Department of Computer Science and Engineering at Kangwon National University (KNU). Before coming to KNU, I was a postdoctoral fellow at the University of Ottawa (uOttawa) and the University of Luxembourg (UL). I received my PhD at the University of Luxembourg under the supervision of Prof. Lionel Briand and in collaboration with Prof. Shiva Nejati, and Dr. Seung Yeob Shin. My research interests are in the area of software testing related to mutation testing, automated verification, fault localization, and automatic repair using fuzzing, search-based approaches, and machine learning. I have been conducting my research closely with industry partners in automotive and aerospace sectors, such as ESA, Huld, GomSpace, LuxSpace, and Blackberry.
