Graduate Program

Who We Are

The Graduate Program in Ecology and Evolutionary Biology provides its students with rich opportunities to study organic diversity, including its origins, maintenance and consequences. Our students' research questions address fundamental issues in basic and applied sciences, span large and small spatial and temporal scales, and apply experimental, observational, theoretical, statistical, molecular and chemical approaches. Some students in the program focus on Discipline-Based Education Research, to develop evidence-based knowledge and practices to improve STEM education.

The program emphasizes broad thinking and encourages students to be both interdisciplinary and independent. While students work with an advisor, many of our students develop research themes that are not derived directly from those of their advisor. Our program may be particularly well suited for students who can therefore take full advantage of Cornell's expansive intellectual and technological resources in the life sciences and related fields.

The Graduate Field of Ecology and Evolutionary Biology

Prospective graduate students apply to Graduate Fields of Study at Cornell rather than departments. Most Graduate Fields are more inclusive than any one Cornell department. Graduate Fields are, in a sense, virtual, and bring together faculty and students with shared intellectual interests, irrespective of their departmental homes.

Students in the Graduate Field of Ecology and Evolutionary Biology (EEB) are all advised by Faculty in the Field of EEB, which include faculty based in 12 departments, including Ecology and Evolutionary Biology, Entomology, Natural Resources and the Environment, Neurobiology and Behavior, Molecular Biology and Genetics, and the School of Integrative Plant Science. Any member of Cornell's Graduate Faculty, from any department, can serve on students' dissertation committees.

Every graduate student will also have a departmental home, which is generally the Department of Ecology and Evolutionary Biology, at least the first year. Afterwards, students have the same departmental home as their primary graduate advisor. Incoming students are guaranteed six years of support, including six years of summer support. Our program has a few standard requirements and milestones on the path to the awarding of the Ph.D.; please see Funding and Program Requirements.

EEB is home to approximately 60 students at any time, coming from a variety of US and international backgrounds. We value diversity in all its dimensions and our student body reflects that! You can further explore program statistics in this useful and interactive dashboard maintained by the graduate school. Make sure to filter the information by the graduate field of EEB.

Why EEB?

A diversity of studies

Graduate students in EEB explore biological diversity from a range of perspectives: from genes to ecosystems, organisms to populations, in the lab and at sites across the globe. Graduate study prepares students for careers in both research and non-research contexts, with evidence-based transferable skills that include project management and problem solving, collaboration and teamwork, written and oral communication, and data analysis and interpretation.

What careers do our graduate students pursue?

Our graduates are interested in a range of academic and non-academic careers, most of which are science related. Many students pursue postdoctoral opportunities as their first position out of graduate school. Over time, students generally move into other positions, including faculty jobs across a wide range of institutions, from R1 universities to 4-year colleges. Other graduates have gone on to professions inside and outside of government, working in environmental conservation organizations and other non-profits, tech, consulting, science communication, medicine, research administration, and other areas.

Funding and Program Requirements

Guarantee of Funding

The Field guarantees six years of support (tuition, stipend, and health insurance), including six years of summer support to all of our incoming Ph.D. students. The numbers vary slightly across years, but for 2023-2024 our standard Ph.D. stipend support includes a 9-month stipend of $32,494 plus summer support. For more information about stipends, go to the Graduate School Stipend Rates page. Students are supported by a variety of funding sources, including Teaching Assistantships or fellowships funded by Cornell University or by external sources. On average, students are supported for half of their program on Teaching Assistantships and half the time on fellowships, but there is considerable variation among students.

Many students obtain external fellowship support from sources such as the National Science Foundation, the Ford Foundation, or similar sources in their home country. Whenever applicable, we strongly encourage prospective students to apply for these types of fellowships in the same year they are applying to Cornell and other graduate schools. For students that are US citizens, the most broadly relevant external fellowship opportunity is the NSF Graduate Research Fellowship Program, which has an annual application deadline in October.

Some graduate students are supported by Graduate Research Assistantships (GRA) in which they work with a faculty member on a grant-funded project, usually on a topic related to the student's own research program. The specific responsibilities of these research-focused positions vary depending on the type of work being pursued.

Teaching and Coursework


All of our students are required to serve as a paid Teaching Assistant (TA) for at least two semesters, working in partnership with faculty to teach undergraduate and graduate courses. We feel teaching is a valuable complement to research, and most teachers realize that teaching is the best way to really learn any subject well. Typical TA responsibilities include leading group discussions, assisting with grading, supervising laboratory or field-course exercises, and providing study assistance to students. Some of our senior grad students take advantage of opportunities to design and teach their own semester-long writing or First-Year Writing seminars. Our graduate TAs win many teaching awards and have earned a university-wide reputation for being approachable, knowledgeable, and inspiring. Many of our grad students have won department and university awards for excellence in teaching over the years.

Cornell offers considerable opportunities to obtain training in teaching and to develop a teaching portfolio through the Center for Teaching Innovation. The department has been very engaged in developing active learning practices in many of its courses.

Graduate Core Course

All first-year graduate students participate in BIOEE 7670, Current Topics in Ecology & Evolutionary Biology. This course provides an introduction to the breadth of research being conducted by faculty in the Graduate Field of EEB and the opportunity to survey recent advances in that subject area more generally. Students find that this exposure to a diversity of people, ideas and viewpoints proves valuable in helping them formulate and fine-tune plans for their own research.

The course includes a workshop that guides students in crafting their own research proposal, which students often use to apply for fellowships or research grant support. In addition, students are introduced to several topics important to professional development, such as mentoring, reviewing manuscripts, presenting talks, etc.

Other Coursework

The graduate core course is the only class required by the EEB graduate program. Students generally take one or two additional courses per semester during their first few years in the program, but these are selected on an individual basis by the student, with guidance from their advisor, launch team, and dissertation committee.

Advisory Committees

Launch Team

Launch teams meet with new, first-year graduate students before the first week of classes in the new Fall term. All EEB graduate students are expected to have basic proficiency in both ecology and evolutionary biology and the launch team establishes a dialog with new students to assess whether there are gaps in foundational areas of ecology and evolutionary biology; if so, the student and launch team discuss a plan to remedy identified gaps.  These teams serve to help the student choose Fall semester courses and generally reach a good balance between class work, research explorations and other activities at Cornell and in the surrounding Ithaca area. Another role of the launch team is to help the student integrate comfortably into the EEB community, and to ensure that nobody falls through the cracks socially or intellectually.

Launch teams are comprised of three EEB Field faculty (the student's probable advisor and two additional faculty members) and one current graduate student. To help the student get to know the full spectrum of EEB faculty, at least one member is usually drawn from outside of the student's main area of scientific concentration.

Dissertation Committee

This committee is also termed the "Special Committee." All students select a Chair of their Special Committee within three weeks of registering with the Graduate School. This Chair is their official faculty advisor. It is common for EEB students to be co-advised by two faculty, but in this case one of the people serves as the Chair for procedural matters. Ph.D. candidates must have a full Special Committee no later than the end of their third semester.

Doctoral candidates must have one Field faculty member, usually their Chair, representing their major subject and at least two other members, from any department at Cornell. Researchers at other institutions can be added to the Special Committee, beyond the required three Cornell members.

Exams and Milestones

A-Exam and Dissertation Proposal

The purpose of the A-exam is to evaluate a student’s ability and preparedness to successfully conduct Ph.D. level research. Students typically take their A-exam (admission to Ph.D. candidacy) by the end of their 5th semester.  The A-exam has both written and oral components. Students write a dissertation proposal and submit it to the special committee two weeks in advance of the oral exam. The oral exam consists of a defense of the proposal, and a broader examination of the student’s knowledge base in areas directly relevant to the thesis. The oral exam begins with a brief oral presentation of the proposal and is followed by questions from committee members. The A-exam is administered by the student's self-selected Dissertation Committee and is a major milestone on the way to the Ph.D.

Special Committee Meetings

After they pass their A-exam, students should convene at least one committee meeting per academic year that they remain in the program. Steady guidance from the committee is likely to help the student as they design and implement their Ph.D. research, and as they start to pursue their targeted careers. Faculty generally enjoy serving on these committees, as committee discussion of grad student research projects are intellectually stimulating and provide a distinctively rich opportunity for faculty-faculty and faculty-student interaction.

Finishing Seminar

EEB graduate students present a finishing departmental seminar on their dissertation work in the Department of Ecology and Evolutionary Biology. The formal requirement is that this seminar be offered sometime in the two months immediately preceding their dissertation defense, but it usually occurs on the same day as the B-exam.


The B-exam (dissertation defense) is the final oral review of the student's dissertation work by their committee. Although it is intellectually rigorous, it is usually also a time of affirmation and celebration for the finishing student, their committee, and their colleagues in the Field.

Application Process

General Admissions Information

The annual admissions cycle starts when students submit an application by the December 1st deadline. Offers of admission and funding decisions are made in February and March, with student acceptances of offers due by April 15. Most students enter the program in the following Fall semester, though under rare circumstances may arrange a deferred admission for the Spring or subsequent Fall semester.

Masters or Ph.D. degree: Virtually all students enter directly into the Ph.D. program. While we have a Masters degree on the books, we very rarely admit Masters students through external applications. If a Masters program is better for you, then we recommend looking into one of the other graduate fields at Cornell with long established Masters programs, such as the Field of Natural Resources & the Environment.

Students are initially admitted to work with one or two faculty advisors, though some later switch advisors as their interests or research themes change. Admission decisions are made by a faculty admissions committee, but it is important for prospective students to identify and establish a connection with potential advisors prior to applying. It is wise to contact faculty whose work interests you, explaining your interests and background and inquiring whether they are actively seeking new students and might have an interest in supervising you. Admission to our program is highly competitive, as we typically admit fewer than 10% of applicants.

Students are accepted from a range of undergraduate majors from the natural sciences, physical sciences, mathematics and humanities. Backgrounds of our students are correspondingly varied: some enter the program directly following their undergraduate degree, others with a Masters degree or other post-undergraduate experience in research, consulting, the Peace Corps, Teach for America, etc. Feel free to send an email to a Current Graduate Student – many of our current graduate students have volunteered to be a resource for students applying to the EEB graduate program. They are happy to answer any questions you may have about their PI’s lab, graduate student life in general, what Ithaca is like, etc. For their contact information, see the list of graduate students with their lab affiliation and areas of research interest.

If you have questions about the application process, contact the Graduate Field Administrator, Patty Jordan. If you have questions about the graduate program as a whole, contact our faculty Director of Graduate Studies, Alex Flecker.

How to Apply


There is a single application deadline each year on December 1.

Identify a Faculty Sponsor
