Professor & Jerry and Kay Henry Endowed Professor
David Mandrus earned his Ph.D. in physics from Stony Brook University in 1992. His dissertation research involved infrared spectroscopy and break-junction tunneling studies of high-temperature superconductors. From 1992-1995 Dr. Mandrus was a postdoctoral associate at Los Alamos National Laboratory. While at LANL, he became interested in the synthesis and crystal growth of new materials, particularly correlated electron materials. In 1995 Dr. Mandrus joined the staff of Oak Ridge National Laboratory, and in 2000 established the “Correlated Electron Materials Group” (CEMG) at ORNL. From 2000 until 2010 Dr. Mandrus served as group leader of the CEMG. In 2010 Dr. Mandrus joined the faculty at the University of Tennessee.
Dr. Mandrus uses the experimental tools of materials synthesis and crystal growth to address cutting-edge issues in materials physics. Recent interests include: (1) discovery and characterization of new unconventional superconductors, (2) discovery and characterization of new collective phenomena in transition metal oxides, especially involving slow dynamics, (3) neutron scattering investigations of exotic magnets, and (4) new materials for thermoelectric refrigeration and power generation. Dr. Mandrus is a Fellow of the American Physical Society and has authored or co-authored more than 250 technical papers that have been cited more than 6,000 times.
