Geoff Rojas is a condensed matter physicist with a Ph.D. from the University of Nebraska-Lincoln. His graduate work was followed by a two-year postdoctoral appointment at the Imaging Characterization user facility at Oak Ridge National Laboratory. His research focused on in situ growth and characterization of ultrathin films using a variety of techniques include scanning tunneling microscopy, local probe spectroscopy, x-ray diffraction, and x-ray and ultraviolet photoelectron spectroscopy. He came to the University of Minnesota in 2013 as a postdoctoral associate to study interface chemistry, printing techniques, and scanning force microscopy.
A committed researcher at the University of Minnesota, his interests include the development of multi-dimensional surface probe techniques, nanoscale characterization of mechanical and chemical properties of active biological systems, and the in situ study of functional materials using both local and integral spectroscopy methods.
