CEP Team @ 3600

The faculty and staff of CEP include clinicians, nurses, administrators, librarians, research analysts, health economists, and a biostatistician. Our multidisciplinary team is well integrated throughout UPHS and within the University setting; the team strategically attends P&T committees, CEQI committees, hospital alliances, technology committees, and more. We also collaborate worldwide with affiliate EPCs through partnerships with Cochrane and AHRQ. Get to know more about our team and their expertise below!
