Biography

I am a public health researcher focused on infectious disease epidemiology, vaccine and immunization research, vaccine regulation, research and development (R&D), and antimicrobial resistance (AMR), particularly the impact of vaccines on AMR. I have strong expertise in evidence synthesis, employing various methods such as systematic reviews, scoping reviews, rapid reviews, and developing policy briefs and guidelines to inform policy, programmatic decisions, and research initiatives, with a keen interest in developing research agendas that drive impactful public health initiatives.
