Matthew R Ryder

R&D Staff Scientist

Dr. Matthew R. Ryder is an R&D Staff Scientist in the Material Sciences and Technology Division. His research focuses on the use of neutron scattering and diffraction in conjunction with density functional theory (DFT) to study the thermal and high-pressure response properties of framework materials and molecular crystals. He is specifically interested in the intricate connections between molecular-scale mechanical and electrical properties and their associated low-energy terahertz (THz) vibrations and the mechanisms behind anomalous behavior such as negative thermal expansion and negative linear compressibility.

Dr. Ryder is originally from the Shetland Islands in the north of Scotland and obtained his M.Chem. degree (First Class Honors) in Chemistry with Computational Chemistry from Heriot-Watt University in Edinburgh and his D.Phil. in Engineering Science from the University of Oxford. Upon completing his D.Phil., Dr. Ryder was awarded a prestigious EPSRC Doctoral Prize Fellowship at the University of Oxford to start his independent research career before moving to ORNL in June 2018.
