Current Research Projects

  • 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. A better understanding of the initial formation and aging of bone and its response to stress is important for improving health. We are making apatite substituted with ions typically found in bone in order to support bone tissue studies. The transformations among crystalline and amorphous forms of calcium phosphates are studied as models of early mineralization. The affect of pressure on bone strength is another area of interest. The nucleation and growth of apatite on silicate surfaces as applied to bone implants are being studied. 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 (azoaromatic polyethers). Modern computational modeling of molecular structure and conformation augments my experimental studies.
