BA in Ecology, Evolution, and Environmental Biology

4 Years On Campus Bachelors Program

Columbia University

Program Overview

Columbia University's Environmental Biology major explores how living organisms interact with their environments, how species evolve over time, and how ecological processes shape populations, communities, and ecosystems. It is a strong fit for students interested in biodiversity, wildlife conservation, environmental research, or the science behind environmental challenges, combining foundational biology with physical sciences, quantitative methods, advanced electives, and research experience.

Curriculum Structure

The university's published requirements are organized by course foundations and advanced electives rather than a fixed year-by-year sequence. The following is a suggested progression, not an official four-year course plan; students should confirm their sequence with an academic adviser.

Year 1 – Foundations in Biology and the Physical Sciences: Students can begin with EEEB UN2001 Environmental Biology I and EEEB UN2002 Environmental Biology II, building an understanding of ecological relationships, evolution, and ecosystem science. Supporting subjects such as CHEM UN1403 General Chemistry I and EESC UN2100 Earth's Environmental Systems: Climate System help establish the scientific foundation needed to investigate environmental processes.

Year 2 – Quantitative and Scientific Skills: Students can strengthen their analytical abilities through EEEB UN3005 Introduction to Statistics for Ecology and Evolutionary Biology, which introduces statistical principles and their practical applications in biological research. Depending on their preparation and course sequence, they also progress through mathematics, chemistry, physics, or earth science requirements.

Year 3 – Advanced Ecology, Evolution, and Conservation: Students select advanced courses across areas such as ecology, animal behavior, conservation biology, evolution, genetics, and organismal diversity. Options such as EEEB UN3087 Conservation Biology allow students to explore conservation challenges, while laboratory-based courses can develop practical skills in scientific observation and investigation.

Year 4 – Research and Independent Investigation: Students bring their learning together through a senior thesis, which involves a research internship, generally in the summer before the senior year, and participation in EEEB UN3991–EEEB UN3992 Thesis Research Seminar. This final stage offers an opportunity to investigate a focused question, engage with scientific research, and develop the independence needed for postgraduate study or research-oriented employment.

Focus Areas

Ecology and ecosystem science; evolutionary biology and genetics; biodiversity and organismal biology; animal behavior; conservation biology; environmental research; quantitative methods and statistics; laboratory and field-based investigation.

Learning Outcomes

Students develop an understanding of ecological and evolutionary processes, the interactions between organisms and their environments, and the scientific principles underpinning biodiversity and conservation. They build quantitative reasoning, research design, evidence interpretation, laboratory or field investigation, and scientific communication skills through their coursework and senior thesis.

Professional Alignment (Accreditation)

Columbia's published Environmental Biology requirements do not identify a separate program-specific professional accreditation. The degree is designed around scientific study and research rather than preparation for a single licensed profession. Students interested in environmental consulting, wildlife management, or specialist scientific roles should check the additional qualifications or postgraduate study required for their intended career.

Reputation (Employability Rankings)

Columbia's E3B department publishes alumni career information, including examples of graduates working in environmental science, conservation, research, and public-sector organizations. However, no program-specific QS or Guardian employability ranking, or verified employment rate and salary figure for this major, was identified in the official sources reviewed.

Experiential Learning (Research, Projects, Internships etc.)

At Columbia, students can connect classroom learning with active research through E3B faculty laboratories, independent research opportunities, and courses that include fieldwork. The department's links with the American Museum of Natural History, the New York Botanical Garden, and the Wildlife Conservation Society provide access to a broader scientific community in New York City. Students can explore these opportunities through the department's research guidance and course offerings.

Practical opportunities and resources include:

- Faculty-led research: Undergraduates can explore research projects with E3B faculty and researchers in other university departments. The department recommends identifying research interests, reading laboratory publications, and contacting faculty whose work aligns with those interests.

- Research internships and senior thesis: Environmental Biology majors complete a senior thesis involving a research internship, generally during the summer before the senior year, alongside the Thesis Research Seminar, EEEB UN3991–UN3992.

- Field courses and field trips: E3B lists field-oriented courses including Forest Ecology, Urban Ecology and Design, Plant Ecophysiology, and Field Botany and Plant Systematics. The department also identifies field trips in courses such as Conservation Biology and Ornithology.

- Laboratory-based learning: The major requires at least one advanced elective with a laboratory component, giving students an opportunity to gain practical scientific experience alongside theoretical study.

- Scientific statistics: EEEB UN3005 Introduction to Statistics for Ecology and Evolutionary Biology develops an understanding of statistical methods and their practical applications in ecological and evolutionary research.

- Connections with scientific institutions: Departmental affiliations with the American Museum of Natural History, the New York Botanical Garden, and the Wildlife Conservation Society broaden the research environment available to students. Specific access, placements, and project availability should be confirmed with the relevant faculty or institution.

Progression & Future Opportunities

Graduates of Columbia's Environmental Biology program can pursue careers that connect biological science, environmental research, conservation, and public policy. The department's published alumni profiles demonstrate a range of outcomes, from environmental scientist and wildlife biologist roles to conservation specialists and research careers, while other graduates continue into advanced academic or professional training.

Potential career pathways include:

- Environmental Scientist: Support environmental assessments, investigate ecological conditions, and contribute to environmental management projects.

- Wildlife Biologist or Conservation Specialist: Study wildlife populations, support biodiversity protection, and contribute to habitat conservation initiatives.

- Research Assistant or Laboratory Technician: Assist with scientific investigations, data collection, laboratory procedures, and research projects.

- Environmental Policy or Sustainability Analyst: Apply scientific knowledge to environmental policy, sustainability initiatives, and conservation planning.

Students can strengthen their transition into employment through several university resources and academic opportunities:

- Career advising and internship support: Columbia's Center for Career Education offers career guidance, professional development, and internship-related resources to help students explore possible career directions and prepare applications.

- Columbia College internship opportunities: The Navab Fellowship Program offers eligible Columbia College undergraduates access to alumni-sourced summer internships, professional development, career counselling, and alumni mentorship. Eligibility and available placements depend on the program's current criteria.

- Research experience and professional networks: E3B's research opportunities and senior thesis can help students develop relevant experience for research positions, conservation organizations, environmental agencies, or graduate programs.

- University–institution connections: E3B's affiliated faculty connections with the American Museum of Natural History, New York Botanical Garden, and Wildlife Conservation Society provide a broader research ecosystem. These affiliations should not be interpreted as guaranteed internships or job placements.

- Employment statistics and salary expectations: Columbia's E3B careers page and alumni directory offer examples of graduate career paths, but the official sources reviewed do not establish a current program-specific employment rate or median starting salary. Prospective students should compare salaries for their intended occupation and location rather than assume a guaranteed outcome.

- Long-term professional development: The program's grounding in biological science, quantitative methods, and research can support progression into specialist roles. Some careers may require a master's degree, PhD, additional technical training, or professional qualifications. The degree itself does not guarantee professional accreditation.

Further Academic Progression:

Students who want to deepen their expertise can consider postgraduate study in ecology, evolutionary biology, environmental science, conservation biology, biodiversity, or related research fields. Columbia's E3B department reports that its graduates pursue graduate study in ecology and evolution, biology, conservation, forensics, and paleoanthropology, as well as health-related and veterinary pathways.

Depending on their interests and preparation, graduates may consider:

A master's degree in ecology, environmental science, conservation biology, or sustainability.
A research-focused master's or PhD in evolutionary biology, organismal biology, or ecological science.
Professional study in public health, veterinary medicine, or another related field, subject to the relevant prerequisites and admissions requirements.
Further training in environmental policy, environmental management, or sustainability.

For students considering research-intensive postgraduate study, Columbia specifically recommends considering additional coursework in organic chemistry and genetics. A strong academic record, research experience, and a well-developed senior thesis can help students prepare competitive applications for further study.
