Education

  • BS, Centre College of Kentucky, 1978
  • PhD, University of Florida, 1983

Research Interests

Separation science, especially the fundamentals and biomedical/pharmaceutical applications of the following voltage- or pressure-driven separation techniques: capillary electrophoresis, electrokinetic chromatography, capillary electrochromatography, and micellar liquid chromatography. Within these techniques, we explore novel separation modes and surfactant aggregate pseudophases (micelles, vesicles, microemulsions); chiral separations; and physicochemical measurements.
