Personal Statement

 Our research interests center around the response of the mitochondria and hemoglobin to environmental stressors (i.e. cyanide, sulfide and radiation).  Electron paramagnetic resonance (EPR), done in conjunction with Prof. Mike Hendrich at CMU, also provides a useful probe for our investigations.


Education

University of South Florida, BS Clinical Chemistry    
Iowa State University, PhD Inorganic Chemistry


Teaching

Environmental Health Chemistry (EOH 2309)
