David M. Lee, M.D., Ph.D., is Global Immunology Therapeutic Area Head for the Janssen Pharmaceutical Companies of Johnson & Johnson where he leads a team focused on end-to-end pipeline and a portfolio of treatments for immune-mediated disease. Under his leadership, Immunology researchers are working to build on the success of our current portfolio, which includes STELARA® (ustekinumab) and REMICADE® (infliximab), two of Johnson & Johnson’s largest products. 

Prior to joining Johnson & Johnson in September 2018, David was based in Basel, Switzerland, where he served as Global Head, Immunology, Inflammation and Infectious Disease Discovery and Translation Area for Roche, and prior to that, as Global Head of Autoimmunity, Dermatology, and Transplant Translational Medicine at the Novartis Institutes for BioMedical Research. In each of these roles, he led on the strategic approaches that fed those companies’ pipelines, prioritized assets, and accelerated their development. His ability to develop external collaborations and to lead and develop his teams was central to his success in each organization.

Before transitioning to the pharmaceutical industry, David was a faculty member at Brigham and Women’s Hospital/Harvard Medical School. While there, his research laboratory focused on disease mechanisms in Rheumatology and he also practiced Rheumatology. As a precursor to his career in industry, while at Harvard, he also participated in co-founding multiple start-ups. Ultimately, one – a biotech – was acquired by a major pharmaceutical company.

He is an active author and speaker, having completed more than 80 peer-reviewed publications and book chapters, and more than 100 lectures/seminars.

David earned his undergraduate degree at Stanford University, where he discovered his fascination with the intricacies of the immune system. He subsequently earned his M.D. and Ph.D. in Microbiology/Immunology from the Duke University School of Medicine. His passion for developing new medicines is rooted in his experiences treating patients as a practicing rheumatologist.
