Generate, document, and communicate high-quality medical insights from the field to inform the medical strategy of the assigned portfolio.
Engage on antimicrobial stewardship, appropriate use, HAIs, and AMR, contextualized to local resistance epidemiology and institutional needs.

Map and engage the hospital multidisciplinary ecosystem: ID services, ICU/critical care, emergency departments, clinical microbiology laboratories, hospital pharmacy, and infection-control committees.
Prepare scientific materials (with Medical Manager approval) and support congresses, medical events, and educational programs; keep local experts' content accurate.
Clinical Research (Support / Facilitation)
Support investigator and site identification, ISR proposals, and local publication input; collaborate on pharmacovigilance activities including RMP and PASS, and on inspection readiness. Study ownership, timelines, and budget remain with the responsible research function.
