Experimental research is being conducted in the following areas: the physics and chemistry of surfaces, including microsensors, catalysis, adhesion, thin film growth, surface crystallography, phase transitions, tribology, and development of new instrumentation; liquid crystals and colloidal crystalization; environmental nuclear radiation; health physics; biophysics, including Fluorescence Microscopy and Spectroscopy, Function and Lateral Organization of Biomembranes, Single Molecule Fluorescence Photophysics, and the biophysics of membranes and macromolecules; low temperature physics, including superconductivity; optical, x-ray, and radio observations of galaxies and clusters of galaxies; general relativity; physics education, investigating student learning. Theoretical work includes studies of galactic formation and stability, atomic and solid state theory, semi-conductors, non-linear systems, pattern formation, chemically-driven microscopic motors and pumps, radionuclide transport theories, statistical mechanics, equilibrium and nonequilibrium phase transitions, and surface physics.
