I received my PhD in Chemistry in the Department of Chemistry and Biochemistry at the University of South Carolina with Dr. John W. Baynes, who studied the role of the Maillard reaction in the development of diabetic complications and in aging. Originally discovered by the French scientist, Louis-Camille Maillard (1878-1936), Maillard chemistry involves non-enzymatic reactions between nucleophilic groups (e.g. a- and e-amines, thiols) of amino acids on proteins and reducing sugars and/or peroxidized lipids.
The reaction is catalyzed by heat, and products of Maillard chemistry form and accumulate in cooked food and contribute to its texture, flavor, and aroma. From its discovery until the late 1970s, the Maillard reaction remained the domain of food chemists. It was at this time that products of Maillard chemistry were identified in vivo, including in humans. After all, as John Baynes likes to say, humans are essentially low-temperature ovens with long cooking cycles. Because Maillard chemistry involves non-enzymatic modification of proteins by reducing sugars, such as glucose, individuals with chronically high levels of blood glucose (i.e. those with diabetes mellitus) accumulate Maillard products on tissue proteins to a greater extent and at a faster rate than those individuals with normal blood glucose levels. One protein modification in particular, glycated hemoglobin, is now used as a marker of long term glucose control in individuals with diabetes. The Maillard hypothesis of diabetic complications states that chronic, cumulative chemical modification of tissue proteins by glucose, and also by oxidized lipids, alters their structure, turnover, and function, ultimately leading to diabetic nephropathy, retinopathy, neuropathy, and cardiovascular disease. My PhD research in the Baynes lab focused on the quantification of Maillard reaction intermediates trapped by pyridoxamine, a vitamer of B6, in biofluids of treated, diabetic animals using liquid chromatography-mass spectrometry (LC-MS) and isotope dilution.
My post-doc was performed in the area of separations coupled with mass spectrometry under the mentorship of Dick Smith at Pacific Northwest National Laboratory (PNNL) with a major focus on metabolomics and minor focus on proteomics. At the time, metabolomics was the latest and least mature (and still is) of the systems biology sciences, and my charge was to bring metabolomics measurement capabilities to a predominately proteomics research group. I initially explored the combination of high pressure, high peak capacity capillary LC separations coupled with FTICR MS and demonstrated that many features (characterized by measured m/z and retention times) could be detected in analyses of a variety of sample types. However, the confident identification (see Sumner et al., Metabolomics, 2007 for guidelines from the Metabolomics Standards Initiative regarding metabolite identification confidence) of large numbers of metabolites in LC-MS data remained elusive, as resources such as Metlin, HMDB, etc were not yet available. For the remainder of my post-doc, I continued to apply LC-MS in metabolomics analyses, eventually also expanding to lipidomics. In additon to my work in metabolomics/lipidomics, I continued to study aspects of diabetes mellitus, including both the role of the Maillard reaction, as well as searching for novel protein or metabolite/lipid markers of both types 1 and 2 diabetes.
Currently, I am the metabolomics technical lead in the Integrative Omics group at PNNL. My research has focused on the development of both global and targeted metabolomics and lipidomics capabilities based on LC and gas chromatography (GC) coupled with mass spectrometry, both for fundamental studies of metabolism/metabolic interactions as well as for biomarker discovery. In addition, I maintain my interest in the Maillard reaction in the context of diabetic complications, and have become involved in various efforts to identify novel biomarkers of both types 1 and 2 diabetes.
