David Mandrus

Professor & Jerry and Kay Henry Endowed Professor

Biography

Dr. Mandrus earned his Ph.D. in physics from Stony Brook University in 1992. His did his postdoctoral work at Los Alamos, and joined ORNL staff in 1995. In 2000 he established a group at ORNL dedicated to the discovery and investigation of quantum materials. In 2010 he became a tenured full professor at UT.  He is a Fellow of the American Physical Society, a recipient of the Gordon Battelle Prize for scientific discovery, and an ISI/Clarivate Analytics highly cited researcher. He currently serves on the National Research Council's Condensed Matter and Materials Research Committee. He also served co-chair of the DOE Basic Energy Sciences workshop on Basic Research Needs for Synthesis Science for Energy Relevant Technology.

Dr. Mandrus leads the Emergent Crystalline Matter (ECM) group at the University of Tennessee (UT) that is focused on the design and discovery of new quantum materials. He and his group members work closely with colleagues at ORNL on the advanced characterization of the ECM group's materials, with a special emphasis on neutron scattering and nanoelectronics. The Mandrus group is particularly interested in finding new materials in which magnetism and electronic transport properties are coupled in surprising new ways. Examples of some of the materials being created by the ECM group include van der Waals magnets that can be mechanically exfoliated to create "single-layer" magnetic materials, and chiral magnets in which the magnetization can twist into exotic spin textures with novel topological properties.
