Study of fundamental and applied aspects of bulk and bio-materials and of surfaces and interfaces with a wide variety of spectroscopic and microscopic techniques. Current interests include the detection, localization and quantification of receptor-ligand interactions between outer membrane proteins and adhesins associated with bacteria and understanding at the molecular level the interactions of these adhesins with the environment. A second area of focus is the application of laser-assisted secondary ion mass-spectroscopy (LASIMS) in the mobilization of trace radionuclides (such as Cs, Co and Sr) by pulsed laser irradiation and its use in homeland defense applications. I have wide experience with a variety of techniques including atomic and chemical force microscopy, time-of-flight secondary ion mass spectroscopy, photoemission and Auger electron spectroscopy, scanning electron microscopy and X-ray microanalysis, powder X-ray diffraction (including thin-film diffraction and reflectivity), small spot X-ray fluorescence spectroscopy using synchrotron radiation, high-resolution vibrational and electronic electron energy loss spectroscopy, spin-polarized inverse-photoemission spectroscopy, and coincidence and nuclear-emission spectroscopy.
