Professor Ursula Mazur joined the physical chemistry faculty at WSU in 1982, after her tenure as a postdoctoral associate in the department. She completed her graduate studies at the University of Michigan and holds an undergraduate degree from Wayne State University. Prior to her graduate work, she spent two years as a research associate at the Detroit Institute for Cancer Research. She is the past chair of the Materials Science and Engineering Program at WSU. She is a member of the Editorial Board of ISRN Physical Chemistry and a Fellow of the American Chemical Society and a Fellow of the American Association for the Advancement of Science.  She holds a Westinghouse Distinguished Professorship  in Materials Science and Engineering.  Professor Mazur is nationally and internationally recognized for her pioneering and innovative work in tunneling spectroscopy and in STM based imaging and orbital mediated tunneling through single molecules and molecular aggregate systems. She is also recognized for her work on  structure – function relationship of photosensing ionic organic materials.

We use a combination of experimental and computational methods to study the molecular-scale chemical, electronic, and material properties of 1, 2 and 3-D nanostructured aggregates fabricated from organic and metal-organic complexes. Our goal is to elucidate the phenomena and principles leading to molecular ordering and behavior at nanometer length-scales, and to correlate these principles with the photophysical properties (including optical absorption, energy transfer, and energy trapping) of the nanostructures. By understanding the fundamentals of the structure – function relationship we can tune the opto-electronic properties of these nanostructures for a particular application (e.g. light harvesting, molecular recognition, and catalysis). We apply the newest tools and techniques of nanometer-scale science, including atomic force microscopy (AFM) and scanning tunneling spectroscopy (STS), high resolution transmission electron microscopy (HRTEM), helium ion microscopy (HIM), micro X-ray diffraction, x-ray photoelectron spectroscopy (XPS), optical spectroscopy, and modeling calculations to study the structure, dynamics, and energetics of molecular assemblies at microscopic length scales.
