Prior to joining Rafael, she served as SVP, Head of US Oncology Medical for Novartis, overseeing the clinical development and medical affairs activities of the Novartis oncology portfolio in the US. Before leading the medical function, Dr. Huizinga built and led the strategic data and digital function for the US Oncology business unit at Novartis. During her time at Novartis, she participated in more than a dozen product and indication launches. Prior to Novartis, Dr. Huizinga was the Chief Health Information Officer at Premier, Inc., where she led quality and population health strategies and the Applied Sciences division that formed partnerships with a number of pharmaceutical companies around evidence generation needs. Earlier in her career, Dr. Huizinga served as the VP of Quality at Lifepoint Health, was an associate at McKinsey & Company, and an Assistant Professor at Johns Hopkins University School of Medicine. She serves as an independent director at HealthMyne, a radiomics company. Dr. Huizinga holds an MD and MPH from Vanderbilt University and is a fellow of the American College of Physicians.

“I am excited to join ImmunoGen at such an important time, and to lead a growing global Medical Affairs function that supports the launch of our pivotal programs and the development of our earlier stage assets,” said Dr. Huizinga. “Healthcare innovation is my passion and I look forward to building a team focused on delivering high-quality data, education, and outcomes for patients, caregivers, healthcare professionals, and payors.”
