Research Interests
Much of my research revolves around my interests in teaching. Projects pursued usually
involve training young investigators how to perform research.
The type of heteropoly tungstates with which most of our work has been focused are those
species based a structure known as the Keggin structure. This Keggin structure has 12 tungsten
atoms and one hetero-atom. These atoms are connected via 40 oxygen atoms.
In a common modification of the Keggin structure, one tungsten atom and its exterior oxygen
atom are replaced with another metal atom and a ligand. Usually this second hetero-atom is a
first row transition metal and the ligand is a water molecule. This latter type of heteropoly is
sometimes called a 1:1:11 species whereas the former type is called a 1:12 species.
Utilization of various techniques and methods to separate and then analyze mixtures are
studied. Attention to the various types of intermolecular forces is important.
Our analyzes of soils has focused on minor constituents in the soil. After extraction analyzes
are normally performed with atomic emission or absorption. Effects of pre-treatment, pH, and
temperature are sometimes studied.
