Overview

The Ph.D. in Plant Science from The University of Arizona prepares you for research and leadership careers in crop improvement through genetics, genomics and advanced technology; with federal and state agencies involved in traditional and digital agriculture; and at academic institutions focused on basic and applied plant sciences.

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

What to expect from the program

As a new thesis-M.S. student, you will rotate through one or two working research labs to let you and your prospective advisor assess how well you work together and to help you begin to build your professional network. Once you join a research lab, you and your advisor will develop a research project and you can expect an intense summer between your first and second year as you execute the projects that will form the basis of your thesis. Coursework typically is spread over two to three semesters.

As a new Ph.D. student, you will generally rotate through two to three labs, to expand the breadth of your training, ensure fit, and begin to build your professional network. 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.
