Robert J. Lad has been at the University of Maine since 1988, and is a Professor of Physics and just recently retired as Director of the Laboratory for Surface Science & Technology, an interdisciplinary research center that focuses on nanotechnology and sensor technology. His research expertise covers areas related to surfaces, interfaces, thin film materials, and sensors. He has received more than 40 grants totaling over $30 million from agencies, including NSF, ONR, DARPA, DOE, NASA, AFOSR, AFRL, ARO, and several industries, to support his research programs. He has more than 80 journal publications and 130 presentations at scientific meetings, and has advised individual research projects for 13 PhD, 6 MS, and 51 undergraduate students.
His laboratory contains a versatile Thin Film Synthesis, Processing & Characterization facility that is equipped with instrumentation including several different thin film deposition techniques, x-ray and uv photoelectron spectroscopies, electron and x-ray diffraction, scanned probe microscopies, and conductivity/Hall effect measurements of sensor devices.
Prof. Lad obtained a B.S. in Materials Engineering from Northwestern University in 1980, and Ph.D. in Materials Science from Cornell University in 1986 working on high temperature gaseous corrosion of metallic alloys. Prior to joining the faculty at the University of Maine, he was a Postdoctoral Associate in the Department of Applied Physics at Yale University, where he studied the surface science of metal oxides, and at the National Synchrotron Light Source at Brookhaven National Laboratory where he performed photoemission studies of the electronic structure of oxide materials.
