Research Interests

My main research interest for many years has been in the study of bacterial or yeast metabolism and physiology using the technique of phosphorus-31 NMR. I have also focused on purifying or characterizing N-acetylglutamate kinase from plant tissue culture (D. carota (carrot) and A. thaliana). Recently my research has expanded into the area of bacterial and plant metabolomics (E. coli and A. thaliana), with a special focus on the interface between carbon and nitrogen metabolism. One of my duties as senior instructor is to develop new undergraduate laboratory exercises, suitable for publication. This type of activity lends itself well for undergraduate independent research projects and summer work.

RESEARCH IN PROGRESS
1. A. thaliana DSP protein characterization (collaboration with Dr. G. Moorhead).
2. E. coli sampling and extraction protocol development (collaboration with the U of C Bio-NMR Metabolomics Center Dr. Weljie and Dr. R. Dowlatabadi).
3. 31-P NMR studies of naturally occurring mutants or genetically engineered lactic acid bacteria (collaboration with Dr. E. van Niel and Prof. P. Radstrom, University of Lund, Sweden).
4. Comparative protein assay techniques for a BCEM 403 laboratory exercise (N. Perry, Dr. E. Prenner).
5. Nitrogen metabolism laboratory exercises for BCEM 443 (M. Gaunt, D. Ontko).
