Assistant Professor, Postharvest Physiology
My research focus is on preserving/improving fruit quality, reducing postharvest losses due to physiological disorders and pathological decays, and lengthening marketability of tree fruit with focusing on sweet cherries and European pears through (1) understanding the metabolic and physiological mechanism of fruit eating quality and storability of the existing and new cultivars; (2) developing postharvest chemical/non-chemical treatments and temperature/atmospheric storage and shipping conditions; and (3) improving horticultural practices.
