Research Plant Physiologist with the USDA Forest Service since 1989, with the HTIRC since July 2001.

Research Interests:

  • woody plant tissue culture
  • genetic modification
  • clonal propagation

Broad interests in plant cell, tissue, and organ culture for tree improvement and production. Applied and fundamental research directed toward germplasm improvement to increase resistance or tolerance to biotic or abiotic stressors. Emphasis on the physiological, anatomical, and biochemical bases for defense mechanisms to pathogen infection. Development of protocols for in vitro selection, somatic embryogenesis, micropropagation, genetic transformation, clonal propagation, and induction of early flowering in forest tree species, with subsequent acclimatization of plant material to greenhouse and field environments. Current species of interest are black walnut, northern red oak, black cherry, butternut, white oak, and green, white, black, and pumpkin ash.
