I have been the manager of the Penn State Plant Disease Clinic since 2009. Prior to this, I conducted research on potato diseases at Penn State and also worked in the Clinic as an assistant diagnostician.

I work closely with the National Plant Diagnostic Network (NPDN) ( and am a member of the NPDN Protocols and Validation Committee. I have trained several undergraduate and graduate students in the Plant Disease Clinic teaching them plant disease diagnostic methods and techniques. I have also helped to organize and develop educational trainings and materials for plant diagnosticians.
