Research Summary
My interests are natural products, chemical ecology, and metabolomics. I am trained in spectroscopic techniques including NMR and other modern analytical tools, such as LC-SPE-NMR, HR-MAS NMR, and high-resolution MS. My recent works are on the metabolomics of biofluids and plants as well as NMR characterization of complex mixtures.
My interest in scents, volatiles, and essential oils brought me to Monell where I am examining how odor character changes with concentration. Although most odor atlases describe the odor character of a given molecule using a single description, odor character can change across intensities. Without a quantitative “odor space,” it is difficult to develop general rules describing how perception shifts with changes in intensity. To develop such rules, we are using trained human panels to measure odor character and building models to predict how much odor perception shifts, and how it changes in odor quality, as intensity changes.
