Teaching

General Plant Pathology Lecture (PLNTPTH 3001), Autumn semester.
Diseases of Ornamental Plants (PLNTPTH 5120), Autumn semester (even years).
Plant Disease Diagnosis (PLNTPTH 5685), Summer semester (odd years).

Research

My research program focuses on the development of sustainable strategies for plant disease management in ornamental crops. In my work, I use a combination of conventional and molecular techniques, combined with field studies, to investigate disease epidemiology, biology and ecology of fungal and oomycete pathogens, from which detection and control strategies are developed.

Extension

The purpose of my program is to develop plant health management strategies to address the disease problems faced by the floriculture, landscape and nursery industries of Ohio. My goal as an extension educator is to enhance knowledge of pathogens’ biology, etiology and epidemiology among extension clientele through development and delivery of educational materials, visits to greenhouse/nursery/golf courses, as well as through participation and presentations at grower-oriented meetings, trade shows, open houses, field days and workshops.
