Research Associate Professor of Physics (IIT), Beamline Scientist (BioCAT)
Participated in the construction and operation of undulator-based BioCAT beamline at the Advanced Photon Source. Designed EPICS-based beamline controls including programming tools for data acquisition and automatic beamline setup and alignment. Supported XAFS and SAXS experiments at the beamline carried by various research groups. Provided administration of BioCAT computers and designed the BioCAT Web site. Studied X-ray reflectivity by magnetic multilayers under the condition of resonant magnetic scattering. Developed the X-ray Server for internet-based calculations in the fields of X-ray Bragg diffraction, reflectivity and scattering.

1993-1997 RESEARCH GROUP "RÖNTGENBEUGUNG", INSTITUTE OF PHYSICS, HUMBOLDT UNIVERSITY OF BERLIN
Guest Researcher
Developed theories and computer programs for the analysis of thin surface structures (multilayers, quantum wires, quantum dot arrays, etc.) with the techniques of grazing incidence X-ray diffraction and scattering. Applied those developments to studies of A3B5 superlattices and quantum wires. Designed and performed synchrotron X-ray radiation experiments at DESY and ESRF. Supervised postgraduate students.
