Plant pathology is an exciting field that combines knowledge from a variety of scientific disciplines to keep our plants healthy and productive. Visit the American Phytopathological Society to learn more about our field and its opportunities. The Department of Plant Pathology and Microbiology at Iowa State University has a simple mission: We benefit society by protecting and enhancing plant health. Please visit our About page to learn more about our department and Iowa State University.
Research in our laboratories range from applied field-based programs to basic fundamental science endeavors.
Organisms of interest: Bacteria, Fungi, Nematodes, & Viruses
Areas of study: Pest Management and Detection; Modeling and Epidemiology; Ecology and Organismal Biology; Genetics, Cell and Molecular Biology, & Plant-Microbe Interactions. Visit our research page for more!

How to Apply:
We suggest prospective graduate students contact a few faculty members that they would consider as their major professor/advisor before applying. This will help the student further understand the research interests of that faculty member, whether or not the faculty member has openings in their lab for a new student, and if the faculty member has funding to support a new student.
There are two routes students can take to join a laboratory in the Department of Plant Pathology and Microbiology. Students can directly apply to the Department of Plant Pathology and Microbiology for either a Masters of Science (M.S.) or Doctor of Philosophy (Ph.D.) degree in Plant Pathology OR students can apply for study with one of Iowa State’s interdepartmental graduate programs and choose to conduct their research in a plant pathology laboratory.
- Certain research labs require a stronger background in genetics, cell biology, molecular biology, bioinformatics, for example, Therefore, these labs prefer students whose graduate degree program requires more of those courses.
- Contact prospective faculty members before applying to determine which is the best course of study for you.
To apply for a degree in Plant Pathology, visit the Graduate College Plant Pathology Application page to get started. All applications for graduate study are handled by the Graduate College.
Formal admission requirements are set by the Graduate College, and PLPM follows those minimum requirements.
All applications are processed through the Graduate College. Applications that meet the minimum requirements will then be forwarded to PLPM.
- Graduate College application form
- Official academic transcripts
- Statement of purpose - A letter describing the applicant's academic background, previous research experience, research interests, and career goals. 1-2 pages
- Three letters of recommendation

Both the Graduate College and PLPM require students to maintain a 3.0 GPA. Graduate students must maintain full-time status to retain stipend and tuition support. Full-time status is at least 9 credits per semester and 1 credit during the summer. MS students must complete 30 credits in order to graduate, Ph.D students must complete 72 credits. Credits are earned through coursework and thesis/dissertation research.
Degree Coursework Requirements
Minor in Plant Pathology
For M.S. students: Two 500/600 level courses and 1 semester of Plant Pathology Seminar (PLP 698). For Ph.D. students: Three 500/600 level courses and 2 semesters of Plant Pathology Seminar (PLP 698).

Graduate Student Handbook
For a complete description of student guidelines in the department, please refer to the Graduate Student Handbook. For more information about the Graduate College policies please refer to Iowa State University Graduate Student Handbook.
Graduate Student Organization
The Plant Pathology Graduate Student Organization (GSO) seeks to encourage learning and research in plant pathology through sponsoring and providing an arena for the communication of plant pathology information from research of interest. This is accomplished by helping organize weekly seminars during the academic year, hosting an annual summer retreat, and organizing informal social events. Every student in the department is considered a member of the GSO. Elections for officer positions are held in December every year.
