Professor of Chemistry

Otterbein University

Inorganic Chemistry

As an inorganic chemist, my interests lie in exploring and understanding the diverse chemistry of the elements within the periodic table. Along this line, my primary teaching is in General Chemistry and Inorganic Chemistry. My research interests focus on the areas of synthetic inorganic chemistry, bioinorganic chemistry and crystallography. In recent years my students and I have focused on understanding the photochemistry of metal halide clusters. I also have developed several instructional web sites including an extensive web site for teaching concepts of point group symmetry.

  • Synthetic Inorganic Chemistry
  • Small-Molecule Crystallography
  • Scientific Visualization and Education
  • PhD in Inorganic Chemistry, 1993

    Northwestern University

  • BA in Chemistry, 1988

    The College of Wooster


My teaching responsibilities are in the areas of General and Inorganic Chemistry and range from first-year courses to advanced upper-level coursework.

  • CHEM 1400 - General Chemistry I

  • CHEM 1500 - General Chemistry II

  • CHEM 2030 - Coding for Chemistry

  • CHEM 3200 - Inorganic Chemistry

  • CHEM 3210 - Inorganic Chemistry Laboratory

  • CHEM 4030 - Introduction to Cheminformatics

  • CHEM 4800 - Structural Methods in Chemistry and Biochemistry

Raman Spectroscopy

Raman Spectroscopy

Raman spectroscopy has been incorporated into many chemistry courses thanks to funding from the National Science Foundation.

Structural Chemistry

Structural Chemistry

Structural methods including X-ray crystallography are being incorporated into a range of courses at Otterbein University



The Symmetry@Otterbein web site helps students and faculty visualize molecular and crystallographic symmetry.
