I am a research scientist of the Nuffield Department of Medicine of the University of Oxford and I am the head of head of the Mathematical Modelling Group of the Oxford University Clinical Research Unit (OUCRU) in Ho Chi Minh City, Vietnam. I am interested in developing mathematical models to understand the within-host and between-host dynamics of infectious diseases, as well as to fit these models to real data. These models help unravel biological mechanisms and contribute to decision making on the prevention and control of infectious diseases. My research interests are the following:

  • Sero-surveillance and vaccine-preventable diseases (VPD): I develop models in order to optimize vaccine policies. These models are based on the use of data generated by a national sero-surveillance system based on 20 hospitals across Vietnam that I co-lead with Pr Rogier van Doorn, director of the Hanoi unit of OUCRU.

  • Antimicrobial resistance (AMR): topics that I am interested in are (i) optimization of empirical treatments, (ii) interactions between AMR and VPD, (iii) relationship between AMR and AMU (antimicrobial usage), co-evolution between virulence and resistance. I collaborate with OUCRU Hanoi (Pr Rogier van Doorn) on a national hospital-based surveillance system, with project ViParc (led by Dr Juan Carrique-Mas) on AMR in chicken farms of the Mekong delta and the Molecular Epidemiology group (Dr Pham Thanh Duy) on Klebsiella pneumonia.

  • Climate change and infectious diseases: I use machine-learning forecasting-based approaches in order to understand the effects of environmental and climatic variables on the epidemiology of infectious diseases. This includes dengue fever, respiratory infections and diarrheal diseases.

  • COVID-19: I develop models aiming at mitigating the COVID-19 burden on hospitals ICUs (intensive care units) and optimizing vaccine policies and collaborate closely with the National Institute of Hygiene and Epidemiology (NIHE) in Hanoi (Dr Pham Quang Thai)
