Research Overview


As an analytical chemist, Sheryl Tucker's research is a distinctive combination of both fundamental and applied studies, involving complex systems ranging from organized media to nanomaterials to biological and environmental substances. The overarching theme is the use of targeted experimental design to understand fully the intricacies of heterogeneous materials to ensure their successful integration in applications that ultimately benefit society. While projects involve many techniques, the Tucker Group primarily focuses on molecular spectroscopy and chemical separations. Because of this expertise, collaborative research projects are also a natural fit.
