Overview

The Ph.D. in Plant Pathology from The University of Arizona prepares you for research and leadership careers in federal and state agencies involved in food safety; in industries pursuing crop improvement through microbiome manipulation; and at academic institutions focused on basic and applied microbial sciences.

Prospective graduate students should always feel free to reach out to faculty whose research interests overlap with theirs to ask if they anticipate accepting new students.

What to expect from the program

As a new Ph.D. student, you will generally rotate through two to three labs, to ensure fit and lab-based funding opportunities. As you settle in a lab, you and your advisor will begin developing a theme for your dissertation projects. You’ll also complete coursework in the first two years and prepare for your comprehensive exam. After passing the exam, your entire focus will be on research and the creation of new and relevant information and knowledge. Your advisor and advisory committee will help you on this journey to becoming a leader and expert in your chosen field.
