Dr. Sunghun Park
Area of Specialization
- Horticultural Crop Genomics / Biotechnology
Biography & Education
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.

Dr. Park’s research interests include both fundamental studies to address unique questions in the role of Ca2+ in vegetable/fruit cell physiology and applied studies to enhance production and nutritional quality of horticultural crops using genomic and plant biotechnology tools.
Currently, he is focusing on plant growth and adaptation mechanisms to abiotic stresses (salinity, freezing and drought), manipulating the expression levels and substrate specificity of ion transporters, development of blossom-end rot tolerant and longer shelf life horticultural crops, Phytoremediation and metabolic engineering of flavonoids for health and nutritional benefits.
