Due to the COVID-19 induced cancellations of the Microscopy & MicroAnalysis, Denver X-ray, and American Crystallographic Association physical conferences this summer, Rigaku will be live webcasting a 3-day virtual Analytical X-ray Convention from our laboratory facility in Texas. The webcasts will take place Tuesday 8/4 – Thursday 8/6 and will feature live seminars on X-ray techniques and live instrument demonstrations.

Dr. Mike Marsh

Title: Research Fellow
Organization: Triclinic Labs

Simon Bates is currently a Research Fellow at Triclinic Labs. He received his PhD in Applied Physics from the University of Hull focusing on the magnetic properties of rare earth materials. Simon’s early work at both Philips NV and Bede Scientific focused on the development of high-resolution X-ray diffraction and X-ray reflectivity methods for the measurement and modeling of advanced materials. His current work at Triclinic focuses on the development of advanced characterization methods for formulated pharmaceutical products based on structure (polymorphism, crystallinity, amorphism) and microstructure (texture, strain, nano-crystalline states) functional relationships in the solid state.

Simon also holds and appointment as an Adjunct Professor at LIU in the Division of Pharmaceutical Sciences. He will be presenting some general concepts of his most recent paper X-ray diffraction from non-crystalline materials: the Debye model, published in The International Tables for X-ray Crystallography in 2019.
