My approach
“Good public-health decisions begin with evidence, but they become meaningful through the people and systems that carry them into communities.”
Field experience informs how I approach surveillance, immunization and capacity strengthening: with attention to context, implementation and trust.

About
Public-health practice grounded in field realities.
I work at the intersection of epidemiology, disease surveillance, immunization, public-health data and emergency preparedness. My experience spans frontline implementation, programme support and the careful translation of surveillance evidence into practical action.
Across assignments with WHO and NCDC, I have supported teams, facilities and public-health systems in varied operating contexts. I bring the same discipline to data and digital health: make the evidence clear, make it usable and keep the people behind it in view.
