Dr. Steven Baertschi is President of Baertschi Consulting, LLC, an Indianapolis, IN based firm specializing in providing solutions to the most difficult stability, impurity, and formulation issues. Retiring from Eli Lilly and Company in early 2015, he brings more than 27 years of experience in the pharmaceutical industry to his consulting firm, with a demonstrated track record of innovation and problem-solving. He received his B.S. degree in Chemistry from Lipscomb University (Nashville, TN) in 1980. From 1980 to 1985 he worked in the environmental analytical area focusing on priority pollutant analysis. He obtained his PhD in Organic Chemistry in 1989 from Vanderbilt University (Nashville, TN) joining Eli Lilly and Co. (Indianapolis, IN) that same year. While at Lilly he was responsible for developing the areas of degradation chemistry, including stress testing, photostability testing, and degradation product identification for small molecule drug candidates. Research interests impurity isolation / structure elucidation, photostability and photochemistry of drugs, mechanisms of drug degradation, reactive intermediates, mass balance investigations, degradation-derived genotoxic (mutagenic) impurities…, and drug-excipient interactions.
Dr. Baertschi is internationally renowned, organizing / chairing numerous scientific conferences and symposia on stress testing, photostability, and impurities; he has published more than 50 scientific articles in refereed journals, more than 25 book chapters, and has edited two editions of a book focused on the topic of pharmaceutical stress testing. Dr. Baertschi has been a member of the American Chemical Society since 1980, the American Association of Pharmaceutical Scientists (AAPS) since 1993, and was named a Fellow of the AAPS in 2007.

Greg Stephenson is the President of PharmaFormFinders (pharmaformfinders.com). He offers services ranging from oversight of the screening for the optimal form for your API or pharmaceutical product by searching its “solid-form landscape” for physical forms by screening for salts, co-crystals, and amorphous forms. Services also include oversight of the collection and interpretation of characterization data and chemical and physical stability (polymorphic, hydrate, or disproportionation/dissociation) data leading to the optimal physical form selection for your product’s presentation.
Greg Stephenson has significant experience solving the most challenging problems of physical form, having solved numerous serious problems in drug development involving control of physical forms that impact dissolution rate, control of crystal morphology that impact flow characteristics and the processing/tableting of materials. He also offers services with respect to evaluation of patents, the structuring of claims for crystal forms in patents and their defense or questions of validity through litigation.
Bernard A. Olsen, Ph.D., is an independent consultant providing expertise in chemistry, manufacturing, and control issues to the pharmaceutical industry.
