is technical staff member and director of the Characterization Facility (CharFac), a set of core research labs in the College of Science and Engineering at the University of Minnesota. Dr. Haugstad received his B.A. in physics from Gustavus Adolphus College and Ph.D. in materials physics from the University of Minnesota following a research fellowship at 3M (composites for electromagnetic absorption or \\\”stealth\\\”). His doctoral research examined metal-semiconductor interfaces and heterostructures in ultrahigh vacuum utilizing synchrotron radiation photoelectron spectroscopy and cryogenic methods. After postdoctoral research with DuPont in the University\\\’s NSF Center for Interfacial Engineering, utilizing scanning probe microscopy (SPM) on soft materials relevant to photographic media, he joined the CharFac; here he continued SPM research primarily in collaboration with industry and added managerial, teaching, service and development responsibilities in the CharFac\\\’s SPM and IBA labs (ion beam analysis including Rutherford backscattering and related techniques). His SPM research program has expanded to include (i) contrast mechanisms in SPM with emphasis on special methods, (ii) nanotribology/nanorheology, (iii) fundamental structure and properties of ultrathin films comprised of polymers and/or small organic molecules (surfactants, crystalline semiconductors), and (iv) thicker biofilms and biomedical coatings.
Greg has been a frequent participant in interdisciplinary symposia and workshops spanning the above topics. Over a period of two decades he has collaborated with companies in research on medical X-ray imaging media, inkjet printing, adhesion/release media, personal care products, biomedical surfaces and coatings, ultrafiltration, and scanning probe instrumentation. He has concomitantly provided analytical services and consulting for an even broader range of technologies. He is a principal investigator in an industrial consortium and a member of the graduate faculty of the Department of Chemical Engineering and Materials Science. His teaching has included graduate, undergraduate and 2-year college curricula, courses in nanostructural imaging and characterization; basic and advanced training classes for core-facility researchers; and national-reach short courses in scanning probe methods.
