Welcome to Ecology and Evolutionary Biology

A concentration in the field of Ecology and Evolutionary biology within Cornell’s Biological Sciences and Environmental and Sustainability Science majors provide undergraduates with an array of opportunities to become immersed in the study of biodiversity, evolutionary biology, community ecology, organismal biology and topics related to sustainability, conservation and global climate change.

Because of the breadth and importance of these issues in modern society, students from a broad range of study fields at Cornell, including Science of Earth Systems and Science & Technology Studies enjoy and value EEB courses.

 Through coursework, field studies, and faculty-directed research projects, EEB students are exposed to a variety of disciplines and habitats ranging from local freshwaters to terrestrial ecosystems, including agricultural landscapes, to tropical oceans, alpine tundra, deserts and tropical rainforests. For a complete list of courses, follow this link to the Cornell Courses of Study.


Courses, Field Studies and Undergraduate Research

The framework of EEB’s class roster for undergraduates is built around our two core courses, Ecology and the Environment (BioEE1610) and Evolutionary Biology and Diversity (BioEE1780). Students can then branch-out to discover …

  • Conceptual principles in ecology and evolution;
  • The taxonomy of worldwide flora and fauna, their ecology, evolution and organismal function;
  • Biodiversity and organism interactions within particular environments and ecosystems (e.g., Marine Ecology, Field Ecology, Limnology).

Over 55% of EEB courses include outdoor or experiential components both off and on campus, enabling students and faculty to expand their horizons beyond the lecture hall. Field study opportunities include:

  • Field Ecology (BioEE 3611)
  • Stream Ecology (BioEE 4560)
  • Spring break in the Galapagos for Biology Scholars (special section of BioEE 1780)
  • Winter session, Patagonia Field Course (BioEE 2525/2526)
  • Organization for Tropical Studies (OTS): well-established and internationally recognized semester-long field courses for undergraduates in places like Costa Rica and South Africa.Two undergraduate students in the field
  • Shoals Marine Laboratory: offers field experiences through courses and research internships on an offshore island  in Maine. Courses include introductory courses that satisfy basic requirements for the Cornell biology major as well as advanced courses. Students at the Shoals Marine Laboratory field station on Appledore Island are pictured to the right.
  • The CORALS Program: The Cornell Ocean Research Apprenticeship for Lynch Scholars provides students with an opportunity to study marine science at Friday Harbor Laboratories.
  • Tropical Field Ornithology (BioEE 2640), held in the Dominican Republic.

EEB faculty are active mentors who sponsor internships and independent research opportunities for undergraduates. Students can participate in lab or field-based research projects on the Cornell campus and in Ithaca NY, as well as study sites that range from Brazil to Alaska, and beyond. Interested? Contact our EEB professors directly to find out how to become a member of their research team.

EEB hosts a thriving group of undergraduates who undertake their own independent research, often culminating in a senior honors thesis. In a typical year, a dozen EEB concentrators graduate with honors recognition for their research accomplishments. Many of these undergraduate projects lead to peer-reviewed scientific publications authored by the undergraduate scholar. If you are intrigued by this opportunity, talk to your research advisor and contact Kristy Long (kll25@cornell.edu), the Curriculum Assistant in the Office of Undergraduate Biology (OUB) during your sophomore or junior year.


Biology majors who have concentrated in Ecology and Evolutionary Biology have the skills needed to enter into a wide variety of career paths in education, research, law, environmental organizations, biology, medicine, and computer science. EEB graduates hold key positions at the New York Botanical Garden, the Environmental Protection Agency, the National Science Foundation, the National Academy of Sciences, the Nature Conservancy and various non-government organizations (NGOs) and industries focused on conservation, environmental issues, or educational outreach. Others have obtained teaching positions or work in research laboratories.

Cornell and EEB alumnus, Bruce Young is NatureServe's Director of Species Science. Based in Costa Rica, Bruce builds collaborations across the Americas to support plant and animal conservation. Bruce is still driven by an undiminishing sense of wonder: “There’s still so much unknown out there; I still have that boy scientist in me, and I want to learn more. I see questions every time I walk outside.” Bruce is pictured here with a beautiful Central American Lyre Snake (Trimorphodon quadruplex).
