Research Interests:

Preharvest and postharvest factors impacting postharvest quality, handling and storage of tropical fruits, vegetables and ornamentals.

My research program's focus is the adaptation and application of newer technology to the improvement of postharvest handling in a integrated and systematic way. This research has led to improvement in production practices, and the postharvest handling and marketing. All the research is done in conjunction and with the support of local industies and individual growers, shippers and marketers.

Current research is focused on the application of newer biotechnologies to understand the control of gene expression during fruit development and ripening. We are particularly interested in the evolution of fleshy fruits and fruit ripening that arose independently numerous times during angiosperm evolution. Directly applicable research includes the impact of preharvest fertilization on pineapple fruit acidity and flesh translucency. We are also involved with an international team working on completing the pineapple genome and looking at gene expression during fruit development. Papaya present some unique physiological changes at the quarter ripe stage and shows increased sensitivity to stresses and chemical treatments. We are also collaborating with an international team looking at gene expression profiles during papaya ripening. Another interest is in taro acridity that is thought to be due to the sharp crystals present in all tissue. Acridity causes itchiness if taro is eaten without cooking. Our research  suggests that it is due to proteins associated with the crystals and we attempting to develop a rapid assay that can be used inplant breeding.
