Dr Chung's teaching philosophy embraces a basic but important principle: "Value Every Single Student". He does not see students as just individuals but believe that they represent the future of Singapore. When an NIE student becomes a teacher, they are likely to teach thousands of students in their career. Teachers play a pivotal role not only in imparting content knowledge to students but more critically to nurture them so that they become well-rounded individuals and contribute positively to Singapore society as respected leaders.

Dr Chung is a senior lecturer in the Physical Education and Sports Science (PESS) Academic Group at the National Institute of Education (NIE), Nanyang Technological University (NTU), Singapore. Prior to joining NIE NTU, Singapore, he led the Sociology of Sport Research Group at Korea National Sport University, the national elite sports centred institute and was the chief of secretary for the President of the Korean Society for the Sociology of Sport.

He currently serves as a chairperson of the Bullying and Cyberbullying Prevention and Intervention Committee at Singapore Korean International School (SKIS). He was also awarded the SKIS Leadership Award 2020 from the SKIS principal for achievement leading as a chairman of the Management Committee.

His research interests lie in analysing Physical Education (PE) and sport-related issues to understand complex links between PE, sport, health and fitness, dance, and recreation, drawing from multiple and disciplinary perspectives. His researches were published in the SSCI journals. The research topics that he has been publishing are the following five areas: (a) analysis of sociological and pedagogical issues in the area of PE and sport research; (b) archaeological and/or genealogical analysis of PE curriculum structure derived from Foucault's theoretical concepts; (c) history of the present as to the emergence and transformation in a wide range of domains such as PE, sport and physical culture; (d) contemporary issues of existence and absence surrounding PE and sport in the local and international contexts; (e) construction of sport policy discourse.

He presents his research with topics of PE and sport at the international conferences organised by International Sociology of Sport Association (ISSA) and the North American Society for the Sociology of Sport (NASSS) regularly.
