I have a three-way appointment in the School of Plant and Environmental Sciences Plant Disease Clinic, 60% clinic manager and diagnostician, 32% teaching, 8% Extension and Service.

I manage the Plant Disease Clinic, I’m responsible for administering the laboratory and daily operation and collaborating on projects related to Diagnostics.  I diagnose plant problems from samples submitted to the clinic, report results, and provide disease management recommendations to clients to promote informed decisions, prevention, and risk mitigation.

I prepare and deliver educational curricula on plant disease and problem diagnosis to various audiences and stakeholders (growers, master gardeners, and extension agents). I maintain the VT Plant Problem Image Gallery as a disease diagnostic resource and promote its use as a monitoring tool.

I teach Plant Problem Diagnostics (PPWS 4154/5154) fall semester and the second class (TBD) in the spring semester.
