Chen is a Fellow of the Royal College of Physicians and a Fellow of the Australasian Chapter of Sexual Health Medicine. 

Chen’s research has focused on improving the management and control of sexually transmitted infections (STIs). Since receiving his PhD in 2006, he has published over 300 papers in peer reviewed journals, with 240 of these published in the last 10 years. His papers have been cited 8500 times and he has an H-Index of 49. Chen has been an investigator on research grants totalling $27 million. He is currently lead investigator on an NHMRC Partnership Project grant (2021-2026) which aims to design and evaluate innovative approaches to testing and control of syphilis in the context of syphilis epidemics in Australia and other countries.

Chen was chair of the STI subcommittee of the Australian Government Ministerial Advisory Committee on Blood Born Viruses and STIs (2015-2018). He was a member of the working group for the 3rd Australian National STI Strategy and chair of the Australasian contact tracing guidelines. Chen has served on several national and state committees responsible for developing policy on gonorrhoea and syphilis control. Chen led the development of the online contact tracing service Let Them Know, which has been used by 140,000 individuals diagnosed with STIs to contact partners. He has led the establishment of the hub and spoke model of sexual health services after this was recommended by the Victorian Government Review of Sexual Health Services in 2019.

Chen has been plenary speaker at several international conferences including the British Association for Sexual Health and HIV Conference 2018 and the European International Union against Sexually Transmitted Infections Conference 2019.
