BA in Ecology, Evolution, and Environmental Biology

4 Years On Campus Bachelors Program

Columbia University

Program Overview

Columbia’s Environmental Biology major gives students an interdisciplinary foundation in ecology, evolution, environmental biology, physical sciences, quantitative methods, and advanced biological study, with opportunities to investigate life from organisms to ecosystems and global processes. It suits students interested in understanding biodiversity, ecological systems, conservation, environmental change, and biological research through a combination of foundational science courses and advanced E3B electives.

Curriculum Structure

Year 1: Students begin by building their biological and scientific foundation through courses such as EEEB UN2001 Environmental Biology I and EEEB UN2002 Environmental Biology II, which emphasize the ecological and evolutionary context of modern biology. Supporting study can include CHEM UN1403 General Chemistry I-Lectures and CHEM UN1404 General Chemistry II-Lectures, or approved environmental-science sequences.

Year 2: Students strengthen their physical-science and quantitative preparation through areas such as chemistry, physics, mathematics, statistics, and computer science. A key program-specific option is EEEB UN3005 Intro-Stat-Ecology & Evol Biol, which introduces statistical principles and their practical application in ecology and evolutionary biology.

Year 3: Students move into advanced Environmental Biology coursework, selecting upper-level EEEB courses in areas such as ecology, evolution, conservation biology, behavior, genetics, morphology, physiology, and diversity. The major requires five advanced electives, generally at the 3000 level or above, with at least one course containing a laboratory component.

Year 4: Students deepen their specialization through additional advanced electives and can complete a research-focused senior thesis. The thesis pathway includes EEEB UN3991 Thesis Research Seminar and EEEB UN3992 Thesis Research Seminar, with the program recommending research-internship experience, generally during the summer before senior year.

Focus Areas: Ecology, evolution, environmental biology, conservation biology, animal behavior, genetics, biodiversity, morphology, physiology, ecosystem science, environmental policy, and quantitative biology.

Learning Outcomes: Students develop the ability to understand biological systems across multiple scales, apply ecological and evolutionary concepts, use quantitative and statistical approaches, conduct biological research, and examine environmental challenges through an interdisciplinary scientific perspective.

Professional Alignment (Accreditation): Columbia’s official E3B materials do not state a separate professional accreditation for the Environmental Biology major. The program instead emphasizes multidisciplinary scientific preparation, advanced coursework, laboratory experience, research, and a potential senior thesis.

Reputation (Employability Rankings): Columbia’s official sources reviewed do not publish a current program-specific employability ranking for Environmental Biology, so no QS or other third-party ranking is stated here. The department does highlight its broad research network, including affiliated faculty from Columbia and organizations such as the American Museum of Natural History, New York Botanical Garden, Wildlife Conservation Society, and EcoHealth Alliance, providing a strong research-oriented environment for students.

Experiential Learning (Research, Projects, Internships etc.)

The BA in Environmental Biology at Columbia University gives students substantial hands-on experience through fieldwork, laboratory courses, faculty-led research, internships, and a required senior thesis. Students can study ecosystems directly in the field, conduct research with E3B faculty, work with biological datasets and modern genomic technologies, and develop an original research project under faculty supervision. The program also offers field-based courses ranging from forest ecology and animal behavior to tropical biology in Kenya, allowing students to apply ecological and evolutionary concepts beyond the classroom.

Practical Learning Opportunities:

Senior Research Internship: Students complete a research internship, generally during the summer before senior year, as part of the required senior thesis experience. Research can involve original field or laboratory work under the guidance of an experienced researcher.
Faculty Research Labs: Undergraduates can join research with E3B faculty and other Columbia researchers, attend laboratory meetings, and explore research areas through the department's undergraduate research opportunities.
Independent Research: EEEB UN3998 allows students to conduct environmental-biology research under a faculty mentor, with the research topic and scope approved before enrollment.
Senior Thesis: Students develop an original research project through EEEB UN3991–UN3992 Thesis Research Seminar, combining research experience with written and oral presentation of their findings.
Forest Ecology Fieldwork: EEEB GU4100 includes ten field trips where students collect quantitative data from different forest environments, analyze ecological patterns, and produce lab reports and presentations.
Tropical Biology in Kenya: EEEB GU4065 provides an intensive 16-day winter-break field experience in Kenya, where students receive practical training in fieldwork and biological research.
Animal Behavior Fieldwork: EEEB S3015 uses fieldwork to develop familiarity with the scientific method, behavioral observation, and research design.
American Museum of Natural History: E3B field courses include laboratory work at the American Museum of Natural History, including Ichthyology and Insect Diversity.
Genomics & Sequencing: EEEB GU4055 uses computational exercises, laboratory activities, fieldwork, and state-of-the-art sequencing instruments so students can generate, analyze, and interpret genomic data.
Wet Laboratories: E3B provides wet-lab access for research, with laboratory safety, chemical hygiene, hazardous-waste, and fire-safety training required before researchers work in the laboratories.
Field-Course Portfolio: Students can choose from field-oriented offerings such as Tropical Biology, Forest Ecology, Urban Ecology and Design, Field Botany and Plant Systematics, Animal Behavior Through Fieldwork, Ornithology, Herpetology, and mammalogy-related courses.
Digital/Computational Tools: The program's genomics coursework incorporates computational exercises alongside laboratory work and sequencing technologies; the official course information does not specify particular commercial software packages.
