Dr. Dieter Isheim is a research associate professor of materials science and engineering at Northwestern University and manages the Northwestern University Center for Atom-Probe Tomography (NUCAPT). After receiving a doctorate in physics and physical metallurgy from the University of Göttingen, Germany, in 1995, he joined Northwestern University for postdoctoral studies in 1996 and was reappointed at Northwestern in the rank of research faculty in 2002. His research interests include phase transformations in solids, nano-structured materials, structure and local composition of interfaces in materials, and structure-properties relationships of materials. He specializes in high-resolution atomic-scale materials characterization and analysis, with a focus on atom-probe tomography, and has published more than 150 research papers.
