Graduated from University of Medicine and Pharmacy at Ho Chi Minh City (UMP HCMC) in 1985, and became an infectious diseases specialist in 1989. I gained an MSc from UMP HCMC in 1998, and an MSc from Flinders University in South Australia in 2001. I have worked with the Hospital for Tropical Diseases (HTD) since 1990, promoted to the Head of Tetanus ICU (1991), and served as Vice-Director from 2006 – 2016. Recognised internationally, I was named an Australian Alumni Ambassador – one of only 12 selected by the Australian Government from across the global network of more than 2.5 million alumni. I was also awarded a 2017 Flinders University Convocational Medal acknowledging my contribution, leadership in my field, and the advancement of professional practice in the research and treatment of tropical diseases. My clinical research interests are wide-ranging, including: clinical research of vaccine-preventable, emerging infectious and also critically ill patients of infectious diseases such as tetanus, diphtheria, hepatitis, rabies, influenza, dengue, sepsis, and COVID-19. I am also interested in long term functional improvement of severe patients by rehabilitation and innovation programs. Because of vast experience in clinical research, I am able to organize clinical trials from the beginning, monitor clinical trials, train international and local guidelines, write academic guidelines of infectious diseases, train Good Clinical Practice (GCP), and work in the field with communities (as consultant or trainer).
