Adjunct Professor of Physics at Illinois Institute of Technology, and Adjunct Professor of Electrical Engineering at the University of Illinois at Chicago. Established program for x-ray lithography at MAX-Lab in Lund University before going to work as a physicist for APS at ANL to establish programs in deep x-ray lithography (LIGA), x-ray microtomography, and high-throughput x-ray microanalysis using synchrotron radiation. Was the Project Director for the design and construction of the $72M Center for Nanoscale Materials (CNM) at ANL, completed September 2007. Was the Associate Division Director of the CNM and the leader of the Nanofabrication & Devices Group at the CNM. Was the Deputy Associate Laboratory Director of the Advanced Photon Source (APS) at ANL, and the Director of the APS Upgrade Project. Was a Senior Advisor and Physicist, Physical Sciences & Engineering at Argonne National Laboratory (ANL). Current research interests are in the areas of advanced micro- and nanofabrication techniques, x-ray optics, x-ray & atom interferometry, hydrogels, molecular dynamics of polymers, nanoscience, nanotechnology, and the applications of synchrotron radiation to technological problems. Co-advisor for 6 Ph.D student theses. Coauthor of over 200 papers and 6 patents.
