A general practitioner by training, I also studied public health and got a PhD at the University of Queensland (UQ) in Australia in 2011. I’ve been working for Pasteur Institute in Ho Chi Minh City (PIHCM) since 1995-now, first as a public health officer on reporting communicable diseases, then I have moved to HIV/AIDS control and prevention field since 1997. I have been assigned Deputy Head of Department for Disease Control and Prevention of PIHCM since 2013, overseeing the HIV sentinel surveillance in southern provinces of Vietnam. Since 2016, I have been assigned another task as team leader of surveillance of non-communicable diseases, with a focus on hypertension and diabetes. Regarding research, I’ve involved in epidemiologic and behavioral studies related to HIV/AIDS, HPV and viral hepatitis. In 2020, I participated in a study of evaluation after responses (AAR) with regard to implementation of measures to control Covid-19. My role was to train the survey team on qualitative tools (Focus group discussion and In-depth interviews), moderate focus group discussion and analyze the qualitative component of data. I am coordinator of a trial of simplified schedules of pneumococcal vaccines in Ho Chi Minh City, funded by the Gates Foundation and in collaboration with MCRI. We completed recruitment of participants and data collection in 2020 and in the process of writing up final results. I hope to involve in another trial of HPV vaccines for risk groups, e.g. female sex workers and MSM in near future.
