Dr. Park states, the general goal of his research program is to "increase the nutritional value and production efficiency of horticultural crops by using biotechnology."  His very active research program includes projects to increase calcium concentrations in fruits and vegetables; metabolic engineering of flavonoids in fruits and vegetables; studying plant adaptation to stresses such as salinity, cold, and drought tolerance; engineering ornamental plants for phytoremediation; and molecular breeding for biofuels.

Dr. Park is the department's tissue culture expert, and he teaches an advanced undergraduate and graduate course on the subject. Outside of the lab, Park enjoys traveling to Galveston, Texas, to ocean fish.
