PhD Scholarship in Geology at Lund University

A new opening PhD position in environmental sciences is available at Lund University, Sweden. The initial contract for this position is four years. The deadline to apply is January 15, 2019.

The Faculty of Science conducts research and education within Biology, Astronomy, Physics, Geosciences, Chemistry, Mathematics and Environmental Sciences. The Faculty is organized into nine departments, gathered in the northern campus area. The Faculty has approximately 1500 students, 330 PhD students and 700 employees.

The Department of Geology has a long and successful history of research with an international reputation throughout the entire geological field and offers nationally leading undergraduate programmes at Bachelor's and Master's levels. About 40 researchers/teachers and 20 research students are active at the department, which consists of two sub-departments: Quaternary Sciences, and Lithosphere and Biosphere Sciences.

It is widely recognized that the emergence and expansion of silica biomineralization in the oceans has affected evolutionary competition for dissolved Si (DSi). This resulted in changes in the global biogeochemical cycles of silica, carbon and other nutrients that regulate ocean productivity and ultimately climate. Today, low DSi reflects its efficient uptake by pelagic silicifiers, principally diatoms. However, little is known about how shifting DSi concentrations from biological uptake have changed in the oceans during the last billion years of Earth's history. In addition, the inputs of DSi, especially from weathering and tectonic processes, has varied over time. The major goal of the overall project is to investigate the interactions between biosilicification in organisms and the environment and how these interactions have evolved through Earth's history.

JOBASSIGNMENT

The PhD study is part of a larger interdisciplinary research project in collaboration with scientists from Jarone Pinhassi's research group at the Centre for Ecology and Evolution in Microbial model Systems (EEMiS) at Linnaeus University providing expertise in ecology, evolution, and microbiology.

The research will utilize stable isotope measurements of biosilicification in fossil material from deep time together with supporting geochemical and geological proxies. The geochemical data will be interpreted in the framework of depositional and diagenetic timing of Si precipitation provided by geological observations to explore the changes in environmental and oceanic DSi concentrations through time.

Eligibility

Students with basic eligibility for third-cycle studies are those who- have completed a second-cycle degree- have completed courses of at least 240 credits, of which at least 60 credits are from second-cycle courses, or- have acquired largely equivalent knowledge in some other way, in Sweden or abroad.

The employment of doctoral students is regulated in the Swedish Code of Statues 1998: 80. Only those who are or have been admitted to PhD-studies may be appointed to doctoral studentships. When an appointment to a doctoral studentship is made, the ability of the student to benefit from PhD-studies shall primarily be taken into account. In addition to devoting themselves to their studies, those appointed to doctoral studentships may be required to work with educational tasks, research and administration, in accordance with specific regulations in the ordinance.

Type of employment

Limit of tenure, four years according to HF 5 kap 7.
