In my research vibrational spectroscopy is used to solve problems dealing with molecular structure. 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. My current focus is on apatite, a form of calcium phosphate, which is the major constituent of bone and is also found as a natural mineral in rocks. We are making apatite substituted with ions typically found in bone in order to support Raman analysis of bone tissue and analyze the transformation of crystalline forms of calcium phosphates. We are also studying the nucleation and growth of apatite on silicate surfaces. In another project we are studying the silane hydrolysis process, developing a Raman detection method and studying the kinetics of the process. The materials I study are diverse and have also included proteins containing the heme group (hemoglobin and cytochrome oxidase), inorganic glasses (germanium diselenide doped with metals) and polymers (azoazromatic polyethers). Modern computational modeling of molecular structure and conformation augments my experimental studies.
