Research Interests

Our group is interested in the process of molecular solvation and how this process affects solution chemistry. The development of a molecular-level understanding of the equilibrium and non-equilibrium aspects of solvation are the focus of our attention. Research efforts have included determining liquid state dynamics in chemical systems including the 1) response of hydrophiles to entrapment within microheterogeneous media (e.g., reverse micelles); 2) conformational changes that occur in proteins, both in bulk solution and at liquid/micelle interfaces; and 3) application of supercritical fluid technology (supercritical carbon dioxide) toward green solvent development. Most recently, we have been interested in the solvation behavior of a model chromophore, coumarin 153, in room-temperature ionic liquids and mixed ionic liquid/cosolvent systems. We use electronic spectroscopic techniques as the primary means of studying solvation, which includes static and dynamic (ps, TCSPC) fluorescence spectroscopies. In addition, emission spectroscopic information is augmented by computational chemistry methods, and ultrafast transient absorption spectroscopy.
