Research interests and specialties are papaya, pineapple, cassava, passion fruit, orchids, native trees, GMO, starch, and fruit.

As Leader of the Biotechnology & Agroforestry Program in the Agricultural Experiment Station, our focus is on research involving the tissue culture micropropagation of tropical plants, starch analysis of genetically enhanced cassava, breeding and selection of papaya, in vitro germination and developmental biology of native orchids, and germination and establishment of rare native trees.  Student projects I have assisted with have included:

  • In vitro regeneration of passion fruit from tendrils;
  • Selection of tissue culture medium for micropropagation of cassava;
  • In vitro rooting of cassava;
  • Selection of transgenic papaya seedlings using DMSO and kanamycin;
  • Computer modeling of cassava growth in vitro;
  • Influence of carbohydrates and containers on micropropagated cassava.
