Dr. Wilson is the founder of Trajectory Healthcare, LLC. He saw an opportunity to bring principles of epidemiology to the healthcare data analytic space as an innovative way to help improve the health of populations, better optimize resources, and reduce overall costs.

In 2010, Wilson was awarded two patents related to analyzing and optimizing “resource allocations in cohort time” from the United States Patent and Trademark Office. These patents have been licensed to Trajectory Healthcare, LLC for use in healthcare and are the basis of new “event-based” analytic software products.

In 2004, Wilson was named one of the top 25 leaders in the nation in Disease Management (DM) by Managed Healthcare Executive, a leading healthcare industry journal. In May 2009, Wilson was invited to present a statement on behalf of the ABQAURP, AHIMA Foundation, CMSA, IHPM, and PHI Institute to the Federal Coordinating Committee on Comparative Effectiveness Research. The statement advocated for “transparency of methods” and the need to reform the peer-review process in comparative effectiveness research. In 2009, he served as a member of the AHRQ’s Health Care Quality and Effectiveness Research (HCQER) study section. In 2010, Wilson served on the AHRQ “Clinical and Health Outcomes Initiative in Comparative Effectiveness” (CHOICE) Grants and the AHRQ “Special Emphasis Panel (SEP)” study section and on the advisory board of the AHRQ-NICHM sponsored “Evaluation of Wellness Program” initiative.

Wilson’s publications include contributor (and associate editor) to the encyclopedic Cambridge World History of Human Disease, commissioned works on disease management or wellness evaluation from the DMAA (now Population Health Alliance), URAC and the Academy Health’s State Coverage Initiatives, a program of the Robert Wood Johnson Foundation. Other writings have appeared in the American Journal of Hypertension, American Journal of Managed Care, Annals of Internal Medicine, Barron’s Weekly, Cambridge University Press, Case-in-Point, Circulation, Disease Management, Duke University Press, Employee Benefit News, Health Affairs, Joint Commission Journal of Quality and Safety, Journal of the American Geriatric Society, Lancet, Patient Safety and Quality, Professional Case Management, Statistics in Medicine, Journal of Health and Productivity, and others. Wilson is also a frequent speaker at national meetings on the use of evidence-based principles to drive care management program improvement and assess impact of population health improvement initiatives.

Wilson received his DrPH in epidemiology from the School of Public Health at University of California, Los Angeles and his PhD in bio-history from BGSU (Ohio); he also did post-doctoral work at the London School of Tropical Hygiene and Medicine and the RAND Corporation. Wilson’s professional positions include Corporate Epidemiologist at Anthem Blue Cross Blue Shield, a faculty research position at the Schools of Public Health at Columbia University, a NIH (NHLBI) post-doctoral fellowship position in cardiovascular diseases and a Fulbright award lectureship at the University of the West Indies, Cave Hill, Barbados.

Wilson has conducted several “Rapid Epidemiological Surveys” (RES) of hypertension and diabetes prevalence in the Caribbean and Africa.

Wilson is also the co-founder (with Gary Montrose) and board chair of a 501c3 non-profit organization, the Population Heath Impact Institute ( This organization advocates for credible, independent, and transparent evaluations of organized population health management programs. The PHI Institute has been awarded grants from the Health Industry Forum at Brandeis University and the Institute for Health and Productivity Management. In 2008, the Institute assembled a national group of health experts to draft a set of standards for impact evaluation. Those standards have formed the foundation of a “Healthcare Transparency & Attribution Program” (H-TAP) for population health programs and the “Methods Evaluation Process” (MEP) certification for individuals.

 Wilson has a wife and two daughters and lives in Loveland, Ohio, a suburb in the northeast sector of Cincinnati where Trajectory was invented in the room above the garage.
