Dr. Ed Gracely received his Ph.D. from Temple University in 1986 and has been a faculty member at Drexel University (or institutions that later merged with Drexel, notably MCP) since then. He has been involved with the School of Public Health almost since its inception, playing a substantial role in the design and implementation of the MD-MPH curriculum and the original statistics and epidemiology blocks in Year-1. He is currently the course director and instructor for the SPH Introduction to Biostatistics course (for a previous version of which he received a Golden Apple award in 2011), and the primary consulting faculty member with the Biostatistics Service Center for College of Medicine consulting requests. He has served in the past as a member of the SPH Educational Coordinating Committee, as Chair of the CBMP (Masters project) Oversight Committee, and he was a long-time member of the SPH Admissions Committee. He is currently a member of the Epidemiology/Biostatistics department curriculum committee.

In addition to his SPH activities, Dr. Gracely also teaches statistics and research design to medical students College of Medicine, gives talks to residents and fellows, provides consultation to researchers in a wide range of basic science and clinical fields, serves on the editorial board of both Pain and Pain Medicine, and has a substantial number of publications reflecting collaborative work with primary researchers. He has served for over 20 years on the institutional animal care and use committee (the IACUC) and has written several versions of a chapter on animal number justification in The IACUC Handbook. His research interests include the logic of multiple comparisons, statistics education, and ethical philosophy. Dr. Gracely is a member of the American Statistical Association, webmaster (and former member) of the ASA's Committee on Human Rights and Scientific Freedom, and the webmaster for the Section on Teaching Statistics in the Health Sciences (from which he received the Distinguished Service Award in 2011). He is active in Statistics Without Borders, which provides pro bono consulting services to low-resource researchers, mostly in the third world.
