Dr. Andrew Callender received his B.S. in chemistry and biology from King College (Bristol, TN), then moved to the University of Michigan. He worked with Prof. Mark Meyerhoff on the electrochemical synthesis and characterization of porphyrin-based conducting polymers as a stationary phase for HPLC, completing the M.S. degree in 2003. His Ph.D. research (2006) was conducted with Prof. Michael Morris, focusing on the development of techniques and instrumentation for high-speed dynamic Raman microspectroscopy of bone tissue. His primary research interests are in the application of novel materials to analytical chemistry; currently this involves the development of materials with unusual optical properties.
