Kurt Sickafus is the Alvin and Sally Beaman Professor in the Department of Materials Science and Engineering at The University of Tennessee – Knoxville. Dr. Sickafus’ research interests primarily relate to the crystal structure and physical properties of complex oxides, particularly oxides that accommodate atomic structural disorder. He has worked mainly on oxides for nuclear materials applications, though his technical interests more broadly include ceramic materials for advanced energy applications. Dr. Sickafus received his B.A. in physics and mathematics from Ohio Wesleyan University and his M.S. and Ph.D. degrees in materials science and engineering from Cornell University. Dr. Sickafus was a post-doctoral fellow in the Cavendish Laboratory (Department of Physics), University of Cambridge, U.K. He then held research staff positions at International Business Machines and Los Alamos National Laboratory. Dr. Sickafus is a Fellow of the American Ceramic Society and a Fellow of Los Alamos National Laboratory.

Michael Koehler has been at The University of Tennessee since 2002.  He obtained his B.S., M.S., and Ph.D. from UT in materials science and engineering.  His dissertation involved 

characterizing magnetostrictive materials using resonant ultrasound spectroscopy, vibrating sample magnetometry, and neutron and X-ray diffraction, among other techniques.  He then continued as a post-doc, during which time he grew 2-D semiconductor crystals using chemical vapor transport.  Upon completion of his post-doc position, he moved on to be the lab manager for the JIAM Diffraction Facility.  As lab manager, Michael trains new users so they can schedule and use the instruments on their own, performs experiments and data analysis for any users who do not want to be trained (at an additional cost), and assists users in designing the best experiment for their particular samples/interests.  

Claudia Rawn
Advisor

Claudia Rawn is an associate professor in the Materials Science and Engineering Department at the University of Tennessee, Knoxville.   She is also the director of the Center for Materials Processing.  Prior to joining the University of Tennessee full time, she was a senior research staff member in the Diffraction and Thermophysical Properties Group at Oak Ridge National Laboratory and a joint faculty member in the University of Tennessee’s Materials Science and Engineering Department.  Her research interests include investigations of crystal structures, phase transitions, and thermophysical properties of materials using in-situ x-ray and neutron diffraction.  She received her B.Sc. from Virginia Polytechnic Institute and State University in materials engineering and her M.Sc. from George Mason University in chemistry, and her Ph.D. from the University of Arizona in materials science and engineering.  Upon completion of her Ph.D., she became a postdoctoral research associate in the Ceramics Department of the "Jozef Stefan" Institute (IJS), in Ljubljana, Slovenia.  After her postdoc at IJS, she joined the Materials Science and Technology Division at ORNL with the Oak Ridge Associated Universities Postdoctoral Fellowship program.  Claudia’s professional activities include being a past secretary of the United States National Committee for Crystallography (USNCCr) and she is a Fellow of ASM International.
