Marc Choisy serves as Group Head of Mathematical Modelling at the Oxford University Clinical Research Unit (OUCRU) in Ho Chi Minh City, Vietnam, and holds an honorary Associate Professor position at the University of Hong Kong's School of Public Health. His work bridges epidemiological modeling with public health interventions across Southeast Asia.
Education:
- MSc in Biostatistics (University of Montpellier)
- MSc in Ecology & Evolution (University of Montpellier)
- PhD in Integrative Biology (University of Montpellier)
Choisy specializes in mathematical modeling of infectious disease transmission, with particular focus on environmental and climatic drivers of epidemics. His research spans dengue, influenza, measles, and SARS-CoV-2 dynamics, examining spatial transmission patterns, vaccine optimization, and antimicrobial resistance. He pioneered the use of Facebook colocation data to map Vietnam's district-level contact networks during the 2020 pandemic, revealing the precise impact of lockdowns on disease spread. His team developed sero-surveillance systems using residual hospital samples to identify immunization gaps, notably demonstrating how absolute humidity drives Vietnam's influenza seasonality gradient from south to north.
His publication trends reveal consistent focus on climate-sensitive diseases (dengue, TB), vaccine-preventable outbreaks, and antimicrobial resistance in agricultural settings. Recent work emphasizes open-data pipelines (2025) and cross-border disease dynamics in urbanizing Southeast Asia.
Professional Activities:
- Associate Editor, PLoS Neglected Tropical Diseases
- Developer of R packages for epidemiological modeling (cutoff, midp)
- Co-leader of Vietnam's hospital-based sero-surveillance system
- Advocate for reproducible research and open data practices
Choisy leads OUCRU's Mathematical Modelling group, which integrates big data analytics with traditional epidemiological methods. His team's work on 18 years of dengue data across 8 countries demonstrated region-wide outbreak synchrony driven by El Niño patterns, while measles sero-surveys revealed critical vaccination gaps below the 95% herd immunity threshold in multiple Vietnamese regions.
