General interests encompass the investigation and development of ionization processes, methodologies, and instrumentation employed in mass spectrometry and the application of mass spectrometry to the elucidation of structural features that govern the functions of biological molecules and to the analysis of organic molecules found in environmental matrices. Individual studies entail development of tandem time-of-flight mass spectrometry (TOF MS/MS); development of electron capture ionization time-of-flight mass spectrometry (ECI TOF MS); investigation of electron capture dissociation of peptides and proteins; proteomics based on protein-function; investigation of protein/nucleic acid interaction; and environmental analysis of fluorinated alkyl substances.
