Ed works in the space of plant genetics and -omics to uncover how genes evolve new functions and confer in plants. His previous work included developmental biology of trichome (hair) cells and improving the digestibility of the drought-tolerant grain, sorghum.
Before completing his PhD, Ed was active in plant taxonomy and collections, with experience finding species, of the genus Hoya, new to science in several countries. He was (and still is) interested in plant diversity and breeding of ornamental plants.
