Vitae

Extension and Research Interests

My extension and research interests are in the area of risk management and crop production economics. Work on horticultural crops has included crop insurance, invasive species, economic evaluation of plum pox virus, high tunnel production systems, alternative apple and peach production systems, irrigation, mechanical harvesters, hydroponic vegetable production, fruit quality, alternative vegetable production systems, and tree fruit IPM. Work on agronomic crops has included evaluation of crop insurance options, organic production systems, crop rotations, herbicide selection criteria, conservation tillage systems, machinery sizing and replacement, and crop harvest and storage systems.  I am also responsible for maintaining cost of production estimates for various crop and livestock enterprises; they are published in three production guides and the numerous publications of the Agricultural Alternatives series.
