With 15+ years of experience spanning medical affairs, clinical research, and direct patient care, I bring a strong clinical foundation and strategic perspective to my role as a Senior Medical Science Liaison at Takeda. Through scientific exchange with healthcare providers, I translate complex clinical data into meaningful discussions that surface field insights that directly influence medical strategy and execution.In my current role, I partner with physicians, pharmacists, and infusion nurses to support the appropriate use of plasma-derived therapies, deepen disease state understanding, and build trusted, long-term relationships. I work closely with cross-functional teams to align field insights with strategic priorities and contribute to initiatives such as real-world evidence generation and medical education.Previously, as a Site Director and Clinical Research Investigator, I led clinical trial operations across multiple therapeutic areas, ensuring regulatory compliance and high-quality data delivery. With over a decade of experience caring for patients, I bring a practical understanding of clinical decision-making and patient needs, reinforcing the importance of translating evidence into meaningful scientific exchange that ultimately supports patient care.I am passionate about bridging clinical practice and medical strategy, and I thrive in roles that allow me to build trusted partnerships, elevate field perspectives within the organization, and contribute beyond traditional MSL responsibilities through cross-functional collaboration and strategic initiatives.
