PPXRD: Pharmaceutical Powder X-ray Diffraction Symposium

XRD Training for the Pharmaceutical Scientist!

PPXRD-16, a joint meeting with the 2nd Spring Pharmaceutical Synchrotron X-ray Powder Diffraction Workshop (SPS-XRPD), will be held 9-12 May 2019 in Switzerland.

PPXRD is designed to create a forum for the exchange of knowledge and cutting-edge ideas among those interested in the combined fields of XRD and pharmaceutical sciences. It typically includes a full-day workshop, followed by several important sessions focused on practical applications of X-ray analysis in the study of pharmaceutical materials. Topics include patent and regulatory issues, formulation, product development, drug delivery, polymorphs, amorphous and nanomaterials, complimentary techniques, and much more.

Since 1999, ICDD has hosted 15 PPXRDs in various parts of the world. The host locations typically rotate and symposiums have been held in USA, Europe, and Asia. The abstracts from previous symposiums are publicly available as well as the presentations, except for the most recent event. The most recent presentations are available to attendees of that year’s event, for one year. After that time, they also  become publically available.

Dr. Thomas Blanton – PPXRD Chair
International Centre for Diffraction Data, Newtown Square, PA, USA

Tom is the Executive Director and Principal Scientist at ICDD. Before joining ICDD he was a Senior Principal Scientist at Eastman Kodak Company where he worked in industrial applications of X-ray diffraction and X-ray fluorescence for 31 years. He was responsible for the operation of the X-ray Spectroscopy Laboratory, utilizing diffractometers for powder, pole figure, nonambient, high-resolution, reflectivity, and two-dimensional XRD. Materials analyzed included inorganics, organics, solid state devices, thin films, corrosion products, ceramics, pharmaceuticals, polymers, and nanomaterials. Tom was also the Technical Leader in the Specialty Materials Development Laboratory. His area of focus was utilization of XRD for microstructure characterization resulting in new materials development for intellectual property and product development. Tom has 180+ publications including 4 book chapters, 46 U.S. Patents and 57 international patents.

Tom has served as a member of the ICDD Board of Directors for the terms 1992-1998 and 2004-2013, serving as Chairman 2008-2012. He has also received the honor of being named an ICDD Distinguished Fellow. Tom has been an instructor at the SUNY Albany and ICDD XRD Clinics for more than 30 years, and has served as a lecturer at the University of Rochester.

Dr. Detlef Beckers
PANalytical, Almelo, The Netherlands
Lead Scientist

Ph.D. in Physics at the Research Center Jülich, Solid State Physics Institute, Germany in 1996.

Dr. Beckers joined PANalytical B.V. in 1996 (Philips Analytical B.V. at that time) in the position of Project Manager XRD (X-ray diffraction). He was responsible for the management of hardware development projects and (pre-) development of new optical XRD modules. He then assumed the position of Market Segment Manager Pharmaceuticals, Food and Life Science where he was responsible for applications and business development, and the co-ordination of the pharmaceutical, food and life science market activities within the company. Today, he serves as Lead Scientist for PANalytical.

Dr. Saito earned his Ph.D. in Material Science at Tokyo Institute of Technology, Tokyo, in 2002. He joined Rigaku in 2011, and has been in charge of product management of X-ray diffractometers, global marketing and now marketing in EMEA.

Dr. Gregory A. Stephenson
Crystal Pharmatech Inc., Fishers, IN, USA
Senior Scientific Advisor

Dr. Greg Stephenson received his Ph.D. degree in Medicinal Chemistry from Purdue University where he conducted his graduate research under the advisement of Professor Stephen Byrn. In 1994, he joined Eli Lilly and Company’s Preformulation Department where he is a Research Advisor responsible for the discovery and characterization of salts and polymorphic forms of potential drug substances.  Much of his work centers around the application of solid state techniques such as Single Crystal and Powder X-ray Diffraction and 13C solid-state NMR spectroscopy, to better understand physical properties of pharmaceuticals. Greg has published over 60 peer-reviewed research articles and patents, serves as Associate Editor for the Journal of Pharmaceutical Sciences, and is an elected Fellow for the ICDD.

Dr. Raj Suryanarayanan
University of Minnesota, Minneapolis, MN, USA
Professor and William and Mildred Peters Endowed Chair College of Pharmacy

Dr. Suryanarayanan (Sury) is a Professor of Pharmaceutics in the College of Pharmacy, University of Minnesota.  He also holds the William and Mildred Peters Endowed Chair in Pharmaceutics. He obtained his Bachelor of Pharmacy and Master of Pharmacy degrees from the Banaras Hindu University, Varanasi, India and M.Sc. and Ph.D. degrees in Pharmaceutics from the University of British Columbia, Vancouver, Canada. His research is focused in the area of solid-state properties of drugs.  His publications in this field deal with phase transitions in solids, implications of in situ phase transitions on product performance, evaluation of concepts of crystallinity and development of new techniques to evaluate crystallinity in solids.  He has developed X-ray diffractometric techniques for the qualitative and quantitative analyses of solid phases, to determine the drug content in intact tablets and to study solid-state reactions.  His research group is currently involved in developing low temperature powder X-ray diffractometric techniques to study frozen and freeze-dried pharmaceutical systems.  He is a consultant to numerous pharmaceutical companies and has served as a member of the USP Expert Committee (excipients test methods). He is a fellow of the American Association of Pharmaceutical Scientists and is the past-chair of the Teachers of Pharmaceutics Section of the American Association of Colleges of Pharmacy.
