Dr. Thomas Layloff received a BA in Psychology and Chemistry, and MS in Organic Chemistry from Washington University in St. Louis, Missouri. He continued his education at the University of Kansas in Lawrence, Kansas where he received a Ph.D. in Analytical Chemistry with a minor in Mathematics. Upon receipt of the Ph.D. he joined the Chemistry Department of St. Louis University as Professor of Analytical Chemistry. During his tenure there he also served as a Science Advisor (Consultant) to the U.S. Food and Drug Administrations St. Louis District Laboratory and its successor National Center for Drug Analysis (NCDA). Upon the retirement of the Director and Deputy Director of NCDA he joined the FDA full-time as Director of the laboratory.
During his tenure as Director of NCDA he also served a temporary and subsequent co-lateral assignment as Directory of the FDA Division of Field Science and Technology coordinating the laboratory operations of FDAs 18 Field Laboratories. During that assignment he directed the establishment of the mission statements, staffing patterns, and recruitment strategies which were used to implement the Commissioners initiative to establish the Field Laboratory Research Centers.
After serving over 20 years as the Director of the St. Louis FDA laboratory he transferred to the Center for Drug Evaluation and Research to serve as Associate Director for Regulatory Standards preparing regulatory concept documents.
He left the FDA to join the United States Pharmacopeia as Vice President and Director of the Pharmaceutical Standards Division. He left the USP to join Management Sciences for Health as Principal Program Associate in the Center for Pharmaceutical Management.
