Greg Haugstad

Technical Staff Member & Director, Characterization Facility (CharFac)

University of Minnesota

Greg Haugstad is technical staff member and director of the Characterization Facility (CharFac) at the University of Minnesota. The CharFac serves nanotechnology-intensive companies as well as academics by providing contract services, analytical methods development and training. The CharFac is part of the Materials Research Facilities Network (www.mrfn.org) via the NSF's MRSEC program, and has served an integral role in an industry-academic consortium (~40 companies, startups to transnationals) for 28 years known as IPRIME (Industrial Partnership for Research in Interfacial and Materials Engineering, www.iprime.umn.edu).

Dr. Haugstad is a condensed matter physicist with degrees from Gustavus Adolphus College and University of Minnesota. Prior to his Ph.D. research at UMinn he had fellowships at Ames Lab and 3M, the latter on nanocomposites for GHz-regime electromagnetic wave absorption (?stealth?) using vector network analysis. His Ph.D. research focused on electronic properties at metal and semiconductor interfaces, employing in situ characterization (soft X-ray and UV photoelectron spectroscopy) at the synchrotron light source Aladdin near Madison, WI. After postdoctoral research with DuPont in a UMinn NSF Engineering Research Center, developing atomic force microscopy (AFM) methods to study interfaces in light-sensitive imaging media, he joined the CharFac in 1994; here he continued nano-intensive industry research collaborations as both principal investigator and hands-on researcher. He added managerial, teaching, service and developmental responsibilities for core labs in AFM as well as ion beam analysis (IBA), which includes Rutherford backscattering (RBS), particle-induced X-ray/gamma-ray emission (PIXE/PIGE) and other methods for elemental and depth-dependent composition and epitaxy. His AFM research program includes (i) information content in diverse imaging and mapping modes, both laterally and vertically (e.g., data cube) sensitive; (ii) methods for nanotribology, nanomechanics and nanorheology, including modulation methods, rate/temperature/humidity dependence and liquid immersion (e.g, colloid probe); (iii) polymeric, organic and biological films and coatings, and microtomed complex materials; (iv) polymer nanocomposites with nanoparticle, carbon nanotube, or 2D fillers, as well as CNT- or graphene-based device constructs.

Greg is a frequent speaker in sessions emphasizing nanoscale characterization. He has collaborated with industry on open research related to inkjet printing and micro/nano-spray coatings; adhesion/release media; personal care films; biomedical device surface modification; polymer-drug nanoparticles and coatings; ultrafiltration media; and nanocomposites. He further engages in contract work with a broad range of clients. Since 2001 he has served on the graduate faculty at UMinn, with a materials characterization emphasis. His teaching has included graduate courses in imaging, spectrometry and nanomechanics; undergraduate characterization labs; nanocharacterization capstone courses for 2-year students; training classes for the CharFac; and national-reach short courses. Related to this educational emphasis, he has written a methods monograph on AFM (Wiley)
