Our Team

At Health Research International, our strength is our people. Although we routinely interview medical and industry experts as part of our research, all of our analysis, surveys, forecasts and regulatory work are performed by our in-house staff of research and clinical specialists and consultants. Please take the time to meet them here, as they will be your best ally for making sound, insightful business and strategic decisions.
