Doctoral researcher in evolutionary genomics University of Helsinki, Finland Project title: Genetic mechanisms behind colour diversity. We are seeking a doctoral researcher to join a Research Council of Finland funded project led by Dr Melanie Brien investigating the genetic and molecular basis of colour pattern diversity in tiger moths. The position is available to start in early 2026, and is fully funded for 3.5 years. The project examines the genetic mechanisms producing and maintaining colour polymorphisms in a group of tiger moth species. This colourful group provides opportunities to investigate potential repeated evolution of novel colour pattern genes, the role of regulatory elements in controlling colour variation, and the maintenance of colour polymorphisms by balancing selection. The specific goals of the PhD project can be influenced by the candidate but could involve a mix of genomic analysis, molecular lab work, insect rearing, behavioural experiments, CRISPR, field work and chemical analysis. We welcome applications from candidates with the following requirements: * Strong interest in evolutionary biology research. * Master's degree in ecology, evolution or related field, or a Bachelor's degree plus relevant research experience. * Interest in field work and ideally a driving licence for this. Basic bioinformatics or molecular lab skills are beneficial. * Excellent written and verbal communication skills in English. What we offer: * Training in molecular lab techniques and bioinformatics analysis. * Opportunities for field work in Europe. * Opportunities to visit collaborating labs. * Funding to attend conferences and training courses. * Performance based salary (job demands level 2-4), 5-7 weeks of annual leave, flexible working hours. * Occupational health care, access to high quality sports facilities and language classes. * A friendly, collaborative and international workplace within the Organismal and Evolutionary Biology Research programme https://www.helsinki.fi/en/faculty-biological-and-environmental-sciences/research/organismal-and-evolutionary-biology. How to apply: Candidates are required to submit their applications via the University of Helsinki's electronic recruitment system here: https://jobs.helsinki.fi/job/Helsinki-Doctoral-Research-in-Evolutionary-Genomics/1327596957/ Applications should include a CV including contact details for two referees, and a one-page cover letter outlining your motivations and how your previous experience/studies are relevant to the project. Informal enquiries are welcome, please contact Melanie Brien (melanie.brien@helsinki.fi). Deadline for applications is 31st October 2025.
