Activities and Interests
- My current area of research is soft condensed matter and biological phyics. using most x-ray scattering methods, but also the atomic force microscope. The focus of my x-ray research is the structure and dynamics of block copolymer systems, using small angle x-ray scattering and the emerging technique of x-ray photon correlation spectroscopy (XPCS). In order to be able to carry out these sorts of XPCS measurements, I played a major role in the implementation of beamline 8-ID at the APS, which now stands as the world's leading facility XPCS. In previous years, I carried out experiments to characterize the structure and behavior of metal and semiconductor surfaces, with special attention to roughening and faceting transitions. I have served on several panels, connected with the synchrotron x-ray community, including the NSLS Scientific Advisory Committee, the BESAC panel on Fourth Generation Light Sources, the LCLS Scientific Advisory Committee, the SSRL Director's Review Panel, NSF panel reviews of the ERL at Cornell and of CHESS.
- I believe I would provide a useful perspective to the APSUO steering committee and, through the APSUO, useful advice to APS management on behalf of the Users, in particular concerning what is important in creating the best possible x-ray source and the best possible x-ray science. I have have extensive experience as a "hands-on" synchrotron user, having carried out my first synchrotron scattering experiment in the early 1980s at SSRL, and my most recent in April 2006 at the APS. In between, I have run many times at SSRL, CHESS, NSLS, and APS, first studying two- dimensional phase transitions in model systems, then the structures and transitions of metal and semiconductor surfaces, and especially the behavior of steps on these surfaces, and most recently the structure and dynamics of polymeric and colliodal soft-condensed matter systems, using SAXS and x-ray photon correlation spectroscopy (XPCS). In the late 1990s, I played a leading role in the development of beamline 8-ID, which currently stands as the world's leading facility for XPCS, and in a fast CCD-based x-ray area detector for XPCS experiments.
