He is also very well known for his integrity, for being a clinician who is committed to always doing the best he can for patients and for building exceptional teams.

"The fusion of science and technology is fast transforming pharmaceuticals R&D. With Hal, we have a new R&D leader who will drive the changes and choices we need to make to be successful in this new environment, and as we look to build the next wave of growth for the company."
