Jeff Schwegman, Ph.D. is currently the founder and chief executive officer of AB BioTechnologies (www.ab-biotech.com) where he develops formulations, lyophilization cycles, determines residual moisture by Karl Fischer, and provides thermal characterization studies including freeze-dry microscopy and DSC. Additionally, Dr. Schwegman specializes in speaking and consulting in parenteral pre-formulation, formulation, analytical, and lyophilization of both small molecules and large biomolecules. He also holds patents and develops new technologies within the lyophilization field. Dr. Schwegman received his BS in Biochemistry from Indiana University in 1992 and began working at Cook Imaging in Bloomington Indiana, where he gained experience in analytical, formulation and process development. In 1999 he began graduate study in the Department of Industrial and Physical Pharmacy at Purdue University under the direction of Dr. Steve Nail, where his focus of research involved studying changes in the physical structure of biological molecules during lyophilization. Dr. Schwegman received his PhD from Purdue University in 2003, and returned to Bloomington where he worked at Baxter Pharmaceutical Solutions as a Research Scientist in the Pharmaceutical Development group. In November 2005, he left Baxter and formed BioConvergence LLC with 3 other founders which specialized in developing new formulations and manufacturing processes for parenteral products. In February 2008, he left BioConvergence, which has become a successful company, to form AB BioTechnologies. He is currently the course Director for a 3-day course called Lyophilization Technology which he teaches through the Center for Professional Innovation and Education. He routinely lectures around the world on formulation, stabilization and process development of lyophilized products.
This webinar will begin with a discussion of the physical properties of materials that are commonly used to formulate freeze-dried products, and the impact that these materials can have on how products freeze-dry (in regards to the physical and chemical integrity). Recorded
This webinar will cover the process and benefits of using an empirical approach to design an optimized lyophilization cycle. In the past, a "trial and error" approach was routinely used as the means of cycle design, often resulting in products that were substandard or cycles that were prohibitively long and expensive.

This webinar will cover the various methods used to determine residual moisture in products ranging from bulk powders, to sterile freeze-died products in vials, to foods. Understanding the different techniques, their limitations, and proper execution will result in more accurate and precise moisture results, which translates into better quality products with longer shelf lives.
