Our Team

Mark Currie, PhD

President and Chief Scientific Officer

Our President and Chief Scientific Officer, Mark Currie, PhD, has made critical scientific contributions over the last 40 years that have greatly advanced understanding of the pharmacology of nitric oxide, guanylate cyclases and cGMP signaling.
