Professional Interests

My research interests center around using mass spectroscopy methodology to characterize metabolic networks. I use metabolomic/lipidomic methodology to characterize fuel dyregulation, and to measure the tissue specific action of insulin in regulating metabolism. Profiling small molecules within metabolic pathways (such as glycolysis, the TCA cycle and the pentose phosphate pathway), in combination with stable isotope assessments of metabolic flux, are powerful tools for describing/characterizing metabolic networks. The mass spectrometric approach for flux measurement I have helped develop measures the flow of carbon, per unit time, through the pathways of glucose metabolism, and serves an in vivo measure of actual metabolic enzyme activity. Stable isotope methods are part of a broad background I have in the use mass spectrometric methods for the study of intermediary metabolism.

 My plans for the future is to integrate metabolomic/lipidomic and stable isotope flux methodologies, for characterizing a broad range of diseases, including Type II Diabetes and obesity. The Stable Isotope and Metabolomics Facility I play a key role in characterizes metabolomic/lipidomic/flux “fingerprints” in cancer biology, and the biology of infectious disease organisms. I think the techniques I have developed for characterizing fuel dysfunctions seen in diabetes and obesity will be valuable for diagnosis, and for designing treatments, in combating cancer, and virulent pathogenic microorganisms.  I look forward to designing new mass spectrometric methods, for use in diabetes and obesity, as well as for combating cancer.
