Graduate study in Cornell's School of Integrative Plant Science (SIPS):

There are five fields of graduate study within SIPS: (i) Horticulture, (ii) Plant Biology, (iii) Plant Breeding, (iv) Plant Pathology and Plant-Microbe Biology, and (v) Soil and Crop Sciences.
The SIPS Graduate Resource Page can help you:

  • Identify graduate fields and faculty research programs that match your interests
  • Decide whether an MS/PhD or MPS program is right for you

Information here focuses on graduate programs in the Field of Plant Pathology & Plant-Microbe Biology.


Welcome to the Field of Plant Pathology & Plant-Microbe Biology, which is managed by the Section of Plant Pathology & Plant-Microbe Biology in the School of Integrative Plant Sciences at Cornell University. From our beginnings as one of the first departments of plant pathology in the country, our tradition of excellence has centered on training graduate students for leadership in the field.  As a graduate student in our Section, you will be part of this extraordinary legacy.

We invite you to explore our three program concentrations

I am studying Potato virus Y (PVY) and its impact on solanaceous crops such as eggplant, pepper, potato, tobacco, and tomato in a mixed cropping system with focus on the methods of introduction and disease spread. I am also interested in the impact that a mixed cropping system has on the virus population, particularly with respect to host range and symptom expression. In another project, I am seeking to identify molecular markers in potato that are indicative of plants in which PVY infection does not result in an observable foliar response, as these plants can contribute significantly to the incidence of PVY in seed potato production
