• Environmental physiology of terrestrial plants
• Horticultural practices on Guam
His research program at the University of Guam is based on two general areas of research: environmental physiology of terrestrial plants and horticultural practices on Guam. The major focus of the environmental physiology research is targeted at understanding the responses of plants to the typical abiotic stresses of the Mariana Islands. This work is primarily whole plant physiology. The horticultural research aims at improving production practices of tropical fruit species and native woody perennial tree species.
