Extension activities

My extension activities encompass postharvest studies of temperate fruit crops with an emphasis on nectarines, fresh market peaches, plums, kiwifruit, apricots, persimmons, pomegranates, Asian pears and table grapes.

Program description

My main goal is to increase fruit consumption. The objectives of my program are:

  • Understanding the role of pre-harvest factors that control fruit quality (taste) at harvest and after shipment.

  • Developing systems to deliver more tasty fruit to consumers.

  • Understanding skin discoloration and internal breakdown on peaches, nectarines, and plums under California conditions.

  • Conducting studies on kiwifruit and stone fruit softening and ripening.

  • Understanding consumer preferences based on fruit quality sensory attributes.


  • Exploring non-destructive techniques to determine maturity and to measure fruit quality.

  • Studying the overseas shipping requirements of fresh commodities.
