Plant Biology Ph.D. Degree

Plant Biology Ph.D.

The Environmental & Plant Biology Ph.D. program provides educational and research experience in plant biology from the molecular to the organismal and ecosystem levels.

Most students are trained within three general areas of study: plant ecology, plant systematics and evolution, or plant molecular and cellular biology.

The program strives to foster communication across and beyond these areas of study to provide unique opportunities to meet each student’s specific career goals. The Ph.D. program is designed to train and prepare students to be successful in teaching and research positions in academia, industry, government, or non-governmental organizations.

A Ph.D. with Molecular and Cellular Biology and Plant Biology also is offered.

Careers with a Plant Biology Ph.D.

The Ph.D. program prepares students to be successful in teaching and research positions in academia, industry, government, and non-governmental organizations. We mentor students in grantsmanship, and they have many opportunities to support their own research with internal and external funding. As Teaching Assistants, students get hands-on teaching experience assisting in a variety of courses and interacting with faculty. Our students also get exposure to the national and international plant biology community through colloquia, seminars, and scientific meetings that will aid them in achieving their post-Ph.D. career goals.

A student with a Ph.D. in plant biology could work at a college or university, teaching or doing research in a variety of specialty areas. He or she also could work in private industry, or governmental agencies dealing with agriculture, horticulture, floriculture, biotechnology or pharmaceuticals, conservation agencies and museums of natural history, environmental consulting firms, food companies, botanical gardens, and arboreta.

Research Areas

Most students are trained within three general areas of study: ecology, systematics and evolution, and functional genomics.

  •  

    Ecology: From Forest Biology to Applied Management


    Environmental & Plant Biology faculty are actively researching various aspects of forest biology, ranging from basic ecological processes to applied management concerns.

  •  

    Functional Genomics


    The plant cell wall biotechnology group studies the structure and function of plant cell wall components in hopes of exploiting this knowledge for the production of valuable biological products.

  •  

    Systematics & Evolution


    Researchers employ independent sources of data to infer phylogenetic relationships and to use the phylogeny as a framework to study character evolution and biogeography.

Plant Biology Ph.D. Courses & Degree Requirements

View Program Handbook

The Ph.D. in Plant Biology requires a minimum of 90 credit hours. Expected time to complete the degree is four years for a student entering with an earned M.S. or five for a student without.

Advising & Program of Study

All new students will report to the Graduate Chair for initial instructions. A student may be co-advised by two Plant Biology tenure-track faculty members. A student may change advisers, but only after approval of the current and potential adviser and the Graduate Chair. If a student leaves his or her adviser, for whatever reason, he or she must find another adviser within four weeks or before the start of the following semester. An unadvised student cannot remain in the Plant Biology graduate program beyond this time limit.

Research & Seminars

A minimum of 60 credits hours of research (PBIO 8950) is required, along with successful completion of four semesters of PBIO 6970 (Seminar) or completion of three seminars and giving a research presentation at Ecolunch in a BIOS or MCB seminar.

Students should enroll in Seminar during the semester in which they are defending their research. The pre-defense seminar is graded by the thesis committee and satisfies one of the four required PBIO 6970 (seminar) courses.

Comprehensive Examination

The Comprehensive Examination for the Ph.D. in Plant Biology will contain a written and oral section. It must be completed before the end of the third year of study and will be planned and organized by the student and adviser.

Plant Biology Comprehensive Examination

Dissertation

The dissertation proposal must describe a comprehensive, multi-study research project. The Dissertation Committee will advise the student of courses and requirements, conduct the comprehensive exam, approve the dissertation research proposal, and conduct the Ph.D. exam for approval of the dissertation. The dissertation will be orally defended in a formal, public presentation (e.g. PBIO colloquium). 

Plant Biology Dissertation

Teaching and Research Assistantships

Each student is trained to conduct independent research in the pursuit of knowledge. Students are mentored in grantsmanship and have many opportunities to support their own research with internal and external funding. Students have hands-on teaching experience because the program provides a teaching assistantship.

As teaching assistants, students have the opportunity to assist in a variety of courses and interact with faculty. Students may additionally have opportunities to supervise and mentor undergraduate students in a research laboratory environment. All students are exposed to the national and international plant biology community through colloquia, seminars, and scientific meetings that will aid them in achieving their post-Ph.D. career goals.
