PhD Positions in Avian Genomics, Speciation & Biogeography University of Toronto - Weir Lab The Weir Lab is looking for PhD students to join us in Fall of 2026. We study how new bird species evolve focusing on the genomic, behavioral, and morphological drivers of speciation across tropical and temperate regions. Our research combines whole-genome sequencing, bioinformatics, and machine learning to explore big-picture questions in evolutionary biology. We value diversity and foster a collaborative, inclusive, and supportive lab environment. What You Might Work On (Some current and recent themes include): - Genomic patterns in hybrid zones of Amazonian bird species - Comparative genomics of speciation, including sex chromosome evolution and genetic incompatibilities - The role of rivers, mountains, volcanic eruptions, or ice ages in promoting speciation - Latitudinal patterns of trait evolution, including changes in plumage and song - Student-led research questions within our broader themes are strongly encouraged Training & Skill Development You'll have the opportunity to build a wide range of skills through: - Fieldwork in Peru, Brazil, or Canada (mist netting, bird handling) - Lab-based work with DNA and whole-genome sequencing (DNA extraction, quantification, library prep) - Bioinformatic analysis of large genomic and phenotypic datasets (coding, pipeline generation, computational skills, data visualization) - Using or developing models and machine learning tools for evolutionary analysis - Publishing your research (we provide close mentoring in scientific writing and project development) What Makes This Lab Different - A focus on creative science many of our projects break new ground by combining diverse data types or exploring fresh angles on classic questions - Broad-scale evolutionary insights through large comparative datasets, often spanning many species and regions Program Details - Department: Ecology & Evolutionary Biology - Lab: Weir Lab (https://www.utsc.utoronto.ca/~jweir/index.html) - Funding: All students receive a competitive, guaranteed funding package for at least 4 years (with M.Sc.) or 5 years (direct-entry PhD). (https://eeb.utoronto.ca/education/graduate/graduate-finances/) Minimal Qualifications - BSc degree in biology or bioinformatics (with a strong focus on evolutionary biology and genetics) - MSc degree is not required (direct entry from undergrad is encouraged with a high academic standing) - Proficiency in English - Preference will be given to applicants with one or more of the following: a drivers license, experience working with birds (bird identification and/or mist netting experience), and bioinformatic experience (coding and/or working with R or other computing languages) Interested? Here's How to Apply Email Prof. Jason Weir (jason.weir [at] utoronto.ca) with: - A short statement of your research interests and skill sets - Your CV - A sample of academic writing - Unofficial transcripts Canadian applicants are expected to apply for NSERC and similar fellowships. International students will require an external fellowship many options exist (e.g., Latin America, EU, etc.). Diversity & Inclusion We welcome applicants from all backgrounds. Our lab has a strong track record of supporting diverse trainees in a collaborative and respectful environment. Viewpoint diversity is considered an asset to the lab.
