Description of Research

Summary Statement of Research Interests

Our research focuses on molecular structure and dynamics of surfaces and interfaces important in life sciences, nano- and bio-technology, and material science. Two complementary aspects of our research program are (1) development of new and more powerful surface spectroscopy techniques with better sensitivity and detection limits, ultrafast time resolution, and improved molecular-level information content; and (2) applications of these techniques for studies of molecular structure, organization, reactivity, and dynamics in these interesting and complex environments. We focus on vibrational spectroscopy because it provides a wealth of information on the molecular structure and organization. To achieve surface selectivity, we utilize even-order nonlinear optical processes, such as Sum Frequency Generation (SFG), which are symmetry-forbidden in isotropic bulk media. Our current projects fall into three categories: (1) Structure and dynamics of the hydrogen bonding network at aqueous interfaces, with the long-range goal of better understanding ‘biological water’ and biomembrane surfaces. (2) Molecular organization of monolayer and surface materials used in organic photovoltaics, nanoscale devices, and biomedical technology. The ‘tailored’ surface materials under investigation include: Langmuir-Blodgett monolayers, Self-Assembled Monolayers, polymer surfaces, and bio-functionalized surfaces. (3) Surfaces of nanostructures: a common motif in many emerging nanotechnology applications involves organic molecules adsorbed on nanostructures to perform the desired physical, chemical, or biological function. We focus on the new effects arising when the characteristic size of the nanostructure approaches the molecular scale. We also explore the enhancement of nonlinear spectroscopic signals due to local nanoplasmon effects, with potential application in sensors with ultra-low detection limits and high molecular information content.
