Graduate position: BC-CAS_Czechia.ButterflyGenomicsHighElevations PhD Position: Genomics of butterflies at high elevations (Please, feel free to distribute to all potential candidates) Closing date: May 8, 2026 We are seeking a motivated PhD student to join our international team at the Biology Centre of the Czech Academy of Sciences. You will be part of an exciting research project aimed at understanding rapid evolution and adaptation in butterflies flying at high elevations. The goal of the PhD work is to infer signatures of genetic adaptation in Pierini white butterflies in the tropical Andes, and to study population structure and differentiation along elevational gradients. You will have the opportunity to generate new genome assemblies and whole-genome resequencing for butterflies that are only found at 1,500-4,000 m in the Andes. The focus of the research is on Phulia and Leptophobia, two rapidly diversifying genera with high-elevation specialists of independent origins. You will benefit from international networking, hands-on training and research mobility, working within a collaborative and multidisciplinary team. Priority will be given to candidates who have co-authored at least one scientific publication (submitted or accepted). Experience with population genetics, bioinformatics and/or comparative genomics is advantageous for this position. Required qualifications: Masters degree in biology or related fields (awarded before start). Good communication skills in English. Independence and documented research productivity. Funding and Environment: The position is fully funded through a combination of research grant salary and student stipend. The PhD program (4 years) is based at the Faculty of Science, University of South Bohemia (https://www.prf.jcu.cz/en). The research facility at the Biology Centre CAS (https://www.entu.cas.cz/en/) is in Ceske Budejovice, a charming historical city in the south of the country, within easy reach of Prague and Vienna. Our working environment (Department of Ecology, Institute of Entomology) is highly diverse and international. How to apply: Send your application in English to pavel.matos@entu.cas.cz, consisting of one single PDF containing the following: Cover letter, outlining your motivation, how your background and skills fit the project, and your potential plans within the research focus of this position (max. 2 pages). CV, including contact details of at least two referees familiar with your work. The deadline for applications is May 8, 2026. The top ranked candidates will be selected for an interview in English. The start date is expected in autumn 2026 (Czechia). For further information, please do not hesitate to contact me.
