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.

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 was also a practicing rheumatologist. 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, and has completed more than 80 peer-reviewed publications, 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.
