Research & Accomplishments 

My research centers around the structure and electronic properties of complex materials including superconducting, magnetic, catalytic, and energy storage materials.

Experimental techniques used in my research include; material synthesis through arc-melting, powder metallurgy, and advanced chemical methods; structural characterization of the samples performed by x-ray powder diffraction and xray absorption fine structure; and measurement of electronic properties by resistivity, magnetic susceptibility, and x-ray absorption spectroscopy. Specific topics of interest include:

  • structural and electrochemical properties of advanced battery materials;
  • in-situ structural studies of catalytic materials for use in fuel cells;
  • structural and electronic properties of magnetoelectric materials and other perovskite materials prepared in the form of nanoparticles and thin films;
  • local structural studies of structural materials for use in nuclear reactors, including in-situ corrosion studies and characterization of nano-crystalline inclusions in steels;
  • development of x-ray optics for synchrotron radiation experimentation.

I also am an active participant in the IIT Center for Synchrotron Radiation Research and Instrumentation (CSRRI); serving as Center Director and as Deputy Director of the Materials Research Collaborative Access Team (MRCAT) which operates an experimental facility for materials research at the Advanced Photon Source (APS). I have been involved in the development of crystal optic devices for delivery and detection of x-rays at synchrotron beamlines.

Since 1992, I have been involved with the International Bridge Building Committee. We organize the Chicago Regional Bridge Building Contest each winter and the International Bridge Building Contest in odd years. This contest has grown, over the past 37 years, to be an integral part of many High School Physical Science curricula.
