The Danish Center for HADAL Research in Nordcee/Department of Biology at University of Southern Denmark seeks applicants for a three-year PhD position to investigate controls on microbial organic matter degradation in deep-sea pelagic and benthic ecosystems, down to the greatest oceanic depth - the hadal realm. Much of the microbial and biogeochemical processes involved in the remineralization of organic matter in the deepest marine environments remain virtually unexplored.
The themes of the PhD project would include (but not be limited to): 1) Studying rates of enzymatic degradation under hadal conditions; 2) Determining how increasing hydrostatic pressure influences the degradation of organic matter; 3) Linking effects of pressure on enzyme activities to changes in gene transcriptional regulation or shifts in microbial community composition and functional potential; and 4) Studying the role of microbial viral infections for the cycling of organic matter in these systems.
The PhD student will be expected to work both independently and as part of a larger research network within the Hadal Center. The PhD project will also have synergies with parallel PhD projects at the centre. The PhD project will consist of a combination of lab- and field (research cruise)-based approaches, with access to state-of-the-art facilities and equipment for microbiological, biogeochemical, molecular, and high-pressure work.
A background in microbiology, biogeochemistry, marine science, environmental chemistry, or a related discipline is desired.
15 November 2021.
