Biography

Research Specialty and Interests

Investigate diseases of major tree fruit grown in Washington State and Pacific Northwest with a focus on applied epidemiology of major pathogens in orchards and its linkage to post-harvest diseases of pome fruit. Develop rational IPM approaches for tree fruit diseases management. Use of standard and molecular tools for accurate risk assessment related to fungicide resistance development and management.

Extension efforts of the program are dedicated to develop and promote innovative and effective methods and technologies to provide appropriate information for multiples stakeholders timely.

Professional Experience and Activities

Employment and Graduate Student Opportunities

If you like fungi and bacteria and are interested in tree fruit pathology, postharvest diseases, and applied epidemiology and you are excited about the idea of working in the number one production region of apple, pear and cherry in the world, you are very welcome to contact me.
