Plant Pathology Ph.D. (Ithaca)

Field of Study

Plant Pathology and Plant-Microbe Biology

Program Description

For a more complete description of the Field of Plant Pathology and Plant-Microbe Biology, please go to

Plant Pathology and Plant-Microbe Biology are the study of plant diseases and the biology of plant-microbe interactions at the molecular to ecosystem levels of organization. The Field of Plant Pathology and Plant-Microbe Biology at Cornell offers graduate degree programs in plant pathology and the biology, genetics and evolution of fungi and oomycetes. To reflect the diversity of academic interests and activities, the Field is organized into three program areas:


  • Plant Pathology (including the concentrations Ecological and Environmental Plant Pathology and Plant Disease Epidemiology)
  • Plant-Microbe Biology
  • Fungal and Oomycete Biology

Plant Pathology Faculty and graduate students  are located in two locations in the College of Agriculture and Life Sciences: the main campus in Ithaca, NY, and the Cornell AgriTech in Geneva, approximately 50 miles (80 km) northwest of Ithaca.

In addition to Plant Pathology and Plant-Microbe Biology, Cornell University offers graduate programs that cover the full spectrum of plant sciences. For more information on graduate studies in related fields of plant sciences, learn more.
