Crystallographic Personnel

The X-ray Diffraction Laboratory is staffed by two full-time Ph.D. level scientists. Together they represent more than 50 years of crystallographic experience. They have published many peer-reviewed papers as well as edited/authored a major crystallographic book : Principles and Applications of Powder Diffraction

The X-ray user committee, chaired by Professor Francois Gabbai, supervises and directs the laboratory. To join the X-ray User committee please notify Dr. Francois Gabbai

Joseph H. Reibenspies, Ph.D. is a Senior Research Instrument Specialist with Texas A & M University. In this role, Dr. Reibenspies manages a team providing all aspects of X-ray Diffraction, including Single-Crystal, Powder and Small Angle Scattering. Dr. Reibenspies is a qualified crystallographer and holds a Ph.D. degree from Colorado State University. Dr. Reibenspies is no stranger to diffraction having spent 30 years as a crystallographer and a chemist, which taught him the importance of structural science

Dr. Reibenspies offers a wide range of services - from crystallographic sciences, to pharmaceutical applications and expert diffraction advice. His book "Principles and Applications of Powder Diffraction" was published in 2008 and has since helped hundreds of people with their powder diffraction needs. Dr. Reibenspies has published over 350 scientific articles, edited scientific journals, served as an expert, and served on committees for the President of Texas A & M University, among others

Dr. Nattamai Bhuvanesh, Ph.D. is a Senior Research Instrumentation Specialist at Texas A & M University. Dr. Bhuvanesh's expertise encompasses Powder- and Single Crystal X-ray Diffraction. With a Ph.D. (Solid State and Structural Chemistry) from the best school known for research in India (Indian Institute of Science), his passion in the structure analysis lead him to his current position as a crystallographer.

Dr. Bhuvanesh has traveled extensively in the USA (35 states, so far) and Canada to train industrial as well as academic users in the practical aspects and applications of X-ray diffraction including data collection and analysis. He has authored/co-authored more than 330 peer reviewed publications (updated September 2020) and has written/edited the book: "Principles and Applications of Powder Diffraction" (Wiley, 2008). Dr. Bhuvanesh has also written a Practical Course on Powder X-ray diffraction extensively used by several universities; sold exclusively by Bruker AXS.
