This fully-funded ARIES PhD studentship explores the role of zinc in the adaptation of diatoms to the extreme conditions of polar oceans. The project focuses on utilizing cutting-edge molecular genetics tools, including CRISPR-Cas and sequencing techniques, to investigate the role of zinc-binding domains in photosynthesis in cold-adapted diatoms. The successful candidate will engage in experimental work with model diatom species, applying skills in algal cultivation, protein biochemistry, and bioinformatics to deepen understanding of the physiological adaptations of polar marine microalgae. Candidates should have a strong foundation in biological sciences, with enthusiasm for molecular microbiology and evolutionary biology.
