The Ord lab (Faculty of Biological and Environmental Sciences, University of Helsinki) is seeking to recruit a doctoral or postdoctoral researcher in forest tree epigenomics and adaptation. The doctoral position is funded for 3.5 years with possibility of extension to 4, while the postdoctoral position is funded for 2years initially with possibility of extension. DNA methylation (DNAme), a component of the epigenome, comprises layer of heritable variation which may evolve more rapidly than the underlying DNA sequence and potentially underlies phenotypic adaptations. Adaptations mediated by DNAme may be particularly important in forest trees which, as long-lived, sedentary organisms, may encounter a wide variety of conditions across a single lifetime. Silver birch (Betula pendula) has a wide distribution range across Eurasia and Scandinavia, and yet populations are highly admixed with limited isolation-by-distance. It is therefore a promising candidate for studying the potential epigenomic basis of adaptation to local conditions. Specifically, the project will use a combination of population (epi)genomic, association mapping and controlled experiments to test whether DNAme contributes to the control of leaf architecture and whether this variation is potentially adaptive in the context of drought. The application deadline is 7thNovember 2025.
