Dr. Clegg’s principal research interest is to examine how fluctuations in dietary and cellular zinc affect cell signaling and gene expression events in cells, embryos, and experimental animals. This research is directed at delineating the rheostat control cellular zinc plays in balancing the processes of cell death and cell proliferation, and examining how imbalances in these two critical processes results in intrauterine growth retardation, immune dysfunction, birth defects, and necrotic/apoptotic cell death. Techniques employed in his research include flame and flameless atomic absorption, inductively coupled plasma spectroscopy OES/MS, rheology, colorimetry, Fourier transformed infrared spectroscopy, flow cytometry, epifluorecence and confocal imaging microscopy, real time pcr, cell/embryo culture, cell transfection, electrophoresis, low pressure chromatography, high pressure liquid chromatography/ gas chromatography/ mass spectrometry.
