Alvin and Sally Beaman Professor and Head
Dr. Sickafus has been an experimental researcher in the field of materials science for about 34 years; investigating structure and properties in metals, polymers, and ceramics, in bulk, thin-film, and composite forms. He graduated from Ohio Wesleyan University in 1978 (BA in Physics & Mathematics), and he received his Ph.D. degree from Cornell University in 1985 (Materials Science & Engineering). Dr. Sickafus also worked as a postdoctoral research assistant in the Cavendish Laboratory, University of Cambridge (1985-1987) and as a staff member at I.B.M. (1987-88) before joining Los Alamos National Laboratory in 1989. He worked as a Staff Scientist at Los Alamos for 22 years before moving to the U. of Tennessee in 2011.
Dr. Sickafus’ primary experimental expertise is in electron microscopy, with an emphasis on transmission electron microscopy (TEM), scanning transmission electron microscopy (STEM), and analytical electron microscopy (AEM) techniques. His research interests are primarily in the areas of crystallography, radiation damage effects, and microstructure of materials. Currently, his research is concentrated on the radiation damage behavior of oxides with structures ranging from spinel to ilmenite to pyrochlore to fluorite to perovskite.
