Teaching:
Diseases of Fruit Crops – Pl P 300. Fall (A/Y). This undergraduate course provides a comprehensive understanding of the diseases of grapes, tree fruits and small fruits grown in Washington State, caused by bacteria, fungi, nematodes, viruses and phytoplasmas. Class lectures and field visits provide inquiry-based, active learning of different aspects of diseases in fruit crops and relate specific concepts learned in the class room to 'real world' situations.
Professional Activities:
- Member, Tropical Plant Pathology Committee (1996-1999) and Virology Committee of the American Phytopathological Society (2005-2008).
- Technical Committee Member, IPM CRSP (USAID) (2006-2009)
