Current Research Projects
In my research spectroscopy is used to solve problems dealing with molecular structure. From the minerals in bone to enhanced surfaces for detection of pharmaceuticals in natural water, nearly any type of sample can be analyzed by Raman spectroscopy because of the flexibility of using a focused laser beam as the light source. Bone is a complex material composed of collagen fibers surrounded by apatite crystals. We study the composition and crystallization of apatite in physiological conditions, substituted with carbonate and other ions, and characterized by Raman, FTIR, XRD, and ICP-OES. Surface Enhanced Raman Spectroscopy (SERS) shows enhanced signals from samples adsorbed on silver and gold nanoparticles. We are developing polymer films embedded with gold and silver nanoparticles that increase the sensitivity and stability of SERS experiments in the field for fast analysis of pharmaceuticals and pollutants in water.
We apply a variety of spectroscopic and diffraction techniques to the study of inorganic, organic and biological materials. The materials I study are diverse and have also included alkylsilanes, proteins containing the heme group (hemoglobin and cytochrome oxidase), inorganic glasses (germanium diselenide doped with metals) and polymers (azoaromatic polyethers). Modern computational modeling of molecular structure and conformation augments my experimental studies.
