Biographies of Organizing Committee

Dr. Cyrus Crowder - PPXRD Chair
International Centre for Diffraction Data, Newtown Square, PA, U.S.A.
Principal Scientist

Dr. Cyrus Crowder is currently the Principal Scientist of the International Centre for Diffraction Data.  He received his BS in Chemistry at the University of Missouri - Rolla in 1976 and followed that with two years of teaching high school physical sciences and mathematics in Missouri.  He returned to the University of Missouri - Rolla to receive an MS degree in Physical Chemistry in 1980 and a PhD in 1982 using neutron diffraction to do structural studies on magnetic intermetallics and their hydrides. Dr. Crowder joined the Dow Chemical Company in 1982 and has been active in the field of X-ray diffraction since that time.  As a member of Dow’s Analytical Sciences Laboratory, he used various X-ray diffraction techniques to solve both R&D and production-related problems in the fields of polymer science, pharmaceuticals, catalysis, ceramics, electronics, and composite materials.  He was co-winner of an IR-100 award in 1987 for his work on the development of the combination DSC/XRD instrument and co-winner of the International Zeolite Association Breck Award in 1989 for his determination of the structure of VPI-5 - a molecular sieve with the largest known pores at the time.  Before his retirement from Dow in September 2007, his responsibilities included Global Technology Steward for X-ray diffraction and tomography and representative for Dow on the DND-Cat Board of Directors at the APS synchrotron, Argonne National Laboratory.  He served for four years on the Board of Directors of the ICDD (1994-1998) and was elected ICDD Fellow in 2000.  Dr. Crowder joined the ICDD as Principal Scientist in September of 2007 following his 25-year career at Dow.

Areas of expertise:  XRD phase identification, phase quantitation by whole pattern methods, crystallography, synchrotron-based powder diffraction, combination thermal/phase analyses (DSC/XRD)

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. Fangling Needham
Emeritus, International Centre for Diffraction Data, Newtown Square, PA, U.S.A.
Senior Scientist

Recently retired, Dr. Needham was a member of the software/database development team in the Science Department of the ICDD. She also developed software/databases in the chemistry industry for PARC and PI. Dr. Needham's educational background includes a B.A. in Earth Science, Southern Connecticut State University, a Ph.D. in Organic Chemistry from Northeastern University and a post graduate certificate in Applied Science/Computer Science from Harvard University Extension. Her experience in research also includes an American Cancer Society Research Fellow on Breast Cancer Research as a graduate student at Northeastern University, a post doctorate research fellow on positron emission tomography at Massachusetts General Hospital, and teaching fellows in chemistry at Northeastern University, and computer science at Harvard University.

Areas of expertise: Organic chemistry, computer science, and basic crystallography

Dr. Kenneth Shankland
Reading University, Reading, U.K.
Reader in Pharmaceutics

Dr. Shankland recently left the STFC Rutherford Appleton Laboratory, after 15 years there, to take up a post as a Reader in Pharmaceutics at the School of Pharmacy at Reading University.  His main scientific interests lie in the area of structures and transformations in pharmaceutical materials and he has been heavily involved in software development for crystallographic analysis of these and other systems. His work, with Professor Bill David of the STFC Rutherford Lab on the subject of global optimisation strategies for the structure determination of molecular materials from powder diffraction data, led to the publication of several key papers in the field and ultimately to the production of the DASH software package which is now co-developed with CCDC.  His underlying interest in the use of computing methodologies to further this work has seen particular utility in the development of highly parallelised versions of DASH and other closely-related codes that run on distributed computing systems.  He is a keen user of laboratory-based X-ray diffraction equipment and a regular user of diffraction beamlines at central facilities.

Dr. Gregory A. Stephenson
Eli Lilly and Company, Indianapolis, IN, U.S.A.
Research 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, U.S.A.
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.
