Research

  • My research is focused in developing capillary electrophoresis, capillary electrochromatography and HPLC methods for the separation and quantification of various analytes including amino acids/proteins in indiginous silkworms, carbohydrates in indigenous food materials, organic constituents in natural products and organic pollutants in enviromental samples.
  • I also have interest in fabricating efficient capillary columns for open tubular capillary electrochromatographic applications.
