About

My journey in Medical Affairs began with a profound curiosity about how medical science can transform lives—and passion for bridging the gap between medical research, strategy and patient outcomes. With a PhD in Immunology, I specialize in driving innovative medical strategies and communications in the pharmaceutical industry. My expertise spans diverse therapeutic areas, such as cardiometabolism, vaccines, and infectious diseases, supported by a strong background in clinical trial development. With extensive experience as a Medical Advisor and Medical Science Liaison (MSL), I have successfully: · Developed and executed global medical and publication plans aligned with pre-launch, launch, and in-market brand strategies. · Led medical teams and managed cross-functional collaborations with clinical operations, regulatory affairs, pharmacovigilance, and commercial teams. · Engaged with key opinion leaders (KOLs) and professional associations to deliver impactful advisory boards, educational programs, and congress symposia. · Authored and contributed to 20+ peer-reviewed publications, including original research articles, reviews, and book chapters. Passionate about synthesizing and communicating complex scientific data. Fluent in English, Spanish, and conversational French, I bring a global perspective to medical plans and communications. I am committed to advancing patient care through innovative solutions leveraging my strategic vision, critical thinking, and relationship-building skills. Let’s connect!
