Columbia University

What you'll study

This PhD emphasises research-led training in evolution, systematics, population biology and their ecological contexts. Early years combine advanced coursework and lab rotations with development of a dissertation research project. Typical topics and modules include:

• Evolutionary theory and mechanisms — population genetics, molecular evolution, adaptive evolution and speciation.
• Systematics and phylogenetics — phylogenetic methods, comparative methods, taxonomy and integrative systematics.
• Population biology and quantitative approaches — demographic models, life-history theory, quantitative genetics and statistical methods for ecological and evolutionary data.
• Ecology and organismal biology — community ecology, behavioural ecology, physiological ecology and field methods.
• Computational and analytical skills — bioinformatics, simulation modelling, R/Python for data analysis, and advanced statistics.
• Research rotations and dissertation research — laboratory, field or theoretical projects under faculty supervision, culminating in an original doctoral dissertation and peer-reviewed publications.

Training is interdisciplinary, with opportunities to take modules in allied departments (e.g. statistics, mathematics, Earth and environmental sciences) and to collaborate with Columbia research centres. Students are expected to pass qualifying examinations and complete teaching or outreach responsibilities as part of their professional development.

Entry requirements

Applicants should normally hold a bachelor’s or master’s degree in biology, ecology, evolutionary biology, genetics, mathematics, statistics or a closely related discipline. A strong background in organismal and evolutionary biology and demonstrable quantitative skills (statistics, programming or mathematical modelling) are important for success.

• Academic transcripts showing relevant coursework and strong academic performance.
• A statement of purpose outlining research interests and fit with faculty strengths.
• Letters of recommendation (typically from research supervisors or academic referees) that speak to research potential.
• A curriculum vitae summarising research experience, publications and technical skills.
• For applicants whose first language is not English, evidence of English proficiency where required by the university.

Successful applicants typically have prior research experience (field, laboratory or computational), familiarity with data analysis and a clear research direction that aligns with departmental faculty expertise. Specific application materials and any standardised testing policies are set by the university and should be checked on Columbia’s admissions pages.

Career prospects

Graduates of this programme pursue a range of career paths that draw on their research, analytical and communication skills. Common trajectories include:

• Academic research and teaching positions (postdoctoral fellowships leading to faculty roles).
• Research scientist roles in government agencies and national laboratories focused on biodiversity, conservation, fisheries, and environmental monitoring.
• Positions in conservation organisations and NGOs developing science-led management and policy.
• Industry roles in biotechnology, environmental consulting, and natural resource management that require expertise in population modelling, genomics or ecological assessment.
• Science communication, policy advising and data science roles where quantitative and interdisciplinary training is an asset.

The programme’s emphasis on publishing, grant writing, teaching experience and interdisciplinary collaboration prepares graduates to compete for research funding and leadership roles across sectors.

Why study at Columbia University

Columbia offers access to a broad network of researchers, facilities and field resources within a major research university and an international city. The department’s strengths in evolutionary biology, ecology and quantitative methods are complemented by collaborative centres such as Columbia’s Earth Institute and the Lamont‑Doherty Earth Observatory, providing opportunities for field-based and large‑scale environmental research.

• Faculty expertise spanning molecular evolution to macroecology and strong opportunities for cross-departmental collaborations (e.g. statistics, mathematics, environmental science).
• Access to institutional research infrastructure and core facilities for genomics, imaging and computational research.
• Proximity to a diverse array of ecosystems for fieldwork in the region and internationally, and connections to conservation and policy organisations based in New York.
• A research culture that encourages publication, grant writing, teaching experience and professional development for careers inside and outside academia.

Prospective students should review Columbia’s departmental pages for up-to-date information on faculty research interests and application procedures to determine fit and prepare a competitive application.
