Eng Eong trained in medicine at the University of Nottingham and then completed his PhD studies at the Department of Microbiology, National University of Singapore. He is a Professor in the Programme in Emerging Infectious Diseases and Associate Dean (Early Research Career Development) in the Office of Academic Medicine, Duke-NUS Medical School. He holds a joint Professorship at the Saw Swee Hock School of Public Health, at the National University of Singapore.
He received the Clinician-Scientist (Senior Investigator) Award by the National Medical Research Council of Singapore, in 2010, 2014 and 2019 and the Singapore Translational Research (STaR) Award in 2023. He was one of six to be named Straits Times Asians of the Year and a member of the team that was named Straits Times Singaporean of the Year, both in 2020. He is a member of the Scientific Advisory Board of Science Translational Medicine and an editorial board member of PLoS Biology.
The global emergence of epidemic dengue and other Aedes-borne flaviviruses is fuelled in part by an incomplete understanding of the determinants of immunity against these viruses and the molecular underpinnings of disease pathogenesis. My laboratory aims to address the gaps in knowledge on dengue pathogenesis and immunity by combining molecular virology and host response investigations with epidemiological and experimental medicine studies, including clinical trials. We aim to define: (1) the mechanisms that govern the clinical and epidemiological fitness of flaviviruses; (2) the immune responses necessary for flaviviral immunity and infection enhancement; and (3) the molecular correlates of clinical outcome of flaviviral infection. By developing deeper understanding in these areas, we hope to contribute to the development of effective vaccines and treatment against dengue and other Aedes-borne flaviviruses.
Studies on flaviviral infection and vaccines in humans have also enabled us to bring our approach in interfacing bench and bedside research to bear on other viral infections and development of non-flaviviral vaccines. ViREMiCS is thus actively working with both academic and industry partners to develop molecular correlates of safety and efficacy to evaluate novel therapeutics and vaccines, including those for COVID-19.
