Greg Stephenson was born in Anderson, Indiana in 1962. After obtaining a B.S. in Chemistry from Ball State University, he earned a Ph.D. in Medicinal Chemistry from Purdue University for research of the solid-state properties of pharmaceuticals under the advisement of Professor Stephen Byrn. He subsequently joined Eli Lilly and Company in its Material Science and Physical Characterizations group in 1994.
He is currently a Research Advisor to the Preformulation Department, where he is responsible for the company’s small molecule X-ray crystallography laboratory and its Salt Screening groups. He was the recipient of Eli Lilly and Company’s Presidential Award in 1995, 1997, 2004 and 2012. He has authored more than 70 peer-reviewed journal articles, is named as co-inventor on 14 different patents, and has authored three book chapters. He was elected as a Fellow of the International Centre for Diffraction’s awards committee. He serves on the Editorial Advisor Board for The Journal of Pharmaceutical Sciences and Pharmaceutical Development and Technology and also reviews articles for numerous journals. He continues to be fascinated by the crystallization behavior of organic compounds and continues to venture into the laboratory on every possible opportunity.

Served as the principal scientist responsible for Eli Lilly and Companies X-ray crystallography laboratory, X-ray powder diffraction laboratory, and thermal analysis laboratory. Work involves the discovery of solid-state forms of drug substances, the characterization of the different solid-state forms, and the selection of the optimal solid-dosage form based on these characteristics. Have participated as an expert witness, having set on the stand in two separate international cases involving patent infringement. Serve as corporate resource for evaluation of patent strength concerning crystalline forms. Other activities include process trouble shooting and support of stability studies.
Purdue University 1990-1994 Research Assistant
Studied under the advisement of Dr. Stephen R. Byrn,
Area of Specialization: Polymorphism and Analytical Chemistry of Pharmaceuticals
Used the combined techniques of single crystal X-ray diffraction, X-ray powder diffraction, 13C-solid-state Nuclear Magnetic Resonance, Thermal Analysis, and Moisture absorption/desorption analysis to study the solid-state behaviour of pharmaceutical substances. Investigated solid-state decomposition reactions using reverse phase HPLC.
