Bill leads the Neuroscience therapeutic area of Janssen Research & Development, LLC in discovering and developing important new therapies for people living with brain disorders. His role is focused on addressing areas where the greatest unmet needs in neuroscience remain, and where the biggest impacts can be made for patients and society, including serious mental illness (such as treatment-resistant depression and schizophrenia) and neurodegenerative disorders (such as Alzheimer's disease). Despite the rich complexities and challenges associated with brain disorders, Bill and his team are firmly committed to ensuring a future where we can both predict and prevent these conditions, and ultimately improve lives and society on a global scale.

Prior to joining Janssen R&D, Bill held the position of President and Chief Executive Officer of Blackthorn Therapeutics, and previously served as the company's Chief Scientific Officer and Head of R&D. He co-founded Blackthorn, which integrates computational and clinical neuroscience and applies a precision medicine approach to creating novel therapeutics for central nervous system (CNS) disorders.

Before Blackthorn, Bill held multiple leadership positions at Theravance Biopharma, including leading the company's research portfolio planning initiative and serving as a member of the strategic partnership team and project team leader for an advanced clinical stage CNS program. He began his career at Merck, where he contributed to the strategic direction of the company's Neuroscience franchise.

Bill is also a member of the Board of Directors for Brown University's Carney Institute for Brain Science and has held leadership positions in the Society for Neuroscience, the Alliance for Artificial Intelligence in Healthcare, the American Physiological Society and the International Brain Research Organization. He has published extensively on neuroscience and brain disorders, with more than 75 publications in scientific journals.

Bill received a bachelor's in Psychology from Swarthmore College and a doctorate in Experimental Psychology from Brown University. He conducted postdoctoral research at the Keck Center for Integrative Neuroscience at the University of California, San Francisco.
