Title Associate Professor Emeritus Education PhD – Cornell University, 1972 Previous Experience Dr. Wu has been with the Physics Department, UMBC since 1974. Prior to that he was a post-doc fellow and instructor at Syracuse University. From 1975 to 1979 he was also a Senior Cancer Research Scientist at Roswell Park Institute. Dr. Wu was a visiting faculty at the University of North Carolina Medical School (1983-84) and the Applied Physics Department, Cornell University (1999-2000). Dr. Wu is a founding partner of Fluorescence Unlimited, Inc., Durham, North Carolina. Professional Interests The principal research interest in our laboratory is to study the dynamic behavior of macromolecules, with an aim to understand the matrix structures and the internal organization of polymers and biopolymers. Our experimental approach is to measure the diffusion coefficient of fluorescently labeled molecules with the techniques of fluorescence recovery after photobleaching (FRAP) or fluorescence correlation spectroscopy (FCS). Depending on sample configurations, experiments are performed using either single or multiphoton excitations in conjunction with a multiphoton confocal microscope. The other areas of research in our laboratory are dynamic light-scattering in polymer solutions, speckle correlation in bacteriorhodopsin-doped polymer films, multiphoton excitations in volume holography and 3-dimensional data storage, and two-photon lithography for microelectronic fabrications.
