Message

My research focuses primarily on epidemiological studies conducted in international field settings. In parallel, I conduct laboratory-based investigations, including pathogen detection and genetic analyses, to gain a comprehensive understanding of the determinants of health and disease. Students who are interested in fieldwork, laboratory experiments, or data analysis are warmly encouraged to contact me.
