Arthur Woll

Education / Experience:

2002 - Present:	Staff Scientist, CHESS, Cornell University
1999 - 2002:	Postdoctoral Fellow, University of Wisconsin-Madison
1993 - 1999:	PhD in Applied Physics, Cornell University, Ithaca, NY
1989 - 1993:	B.A. Physics, Grinnell College, Grinnell, IA

Research interests:

Advances in x-ray fluorescence and other x-ray imaging and spectroscopy techniques, especially instrumentation, optics, methods, and applications. New techniques include nanofabricated x-ray optics, especially for confocal x-ray fluorescence, 3D x-ray imaging at the micron and sub-cellular scale. Application interests span mechanisms of metal uptake, transport, and signaling in plants, mineral and metal oxidation distributions in soils and rocks, recovering lost images and the origins of buried paintings, manuscripts, and daguerreotypes. I also have a background in and continue to support research involving the characterization of thin films, especially in-situ studies of thin film growth.
