Doctoral student in Geology - Hiring in process/Finished, not possible to apply

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 Earth’s history. The major goal of the overall project is to investigate the interactions between biosilicification in diatoms and the environment and how these interactions have evolved through Earth’s history.

Job assignement
We are seeking a highly motivated Doctoral Student within DEVOCEAN, a five-year ERC project assessing the evolution of diatoms through geologic time. The question regarding when diatoms evolved is greatly debated in the literature with molecular clocks placing the origin of diatoms near the Triassic–Jurassic boundary, although no fossil diatoms exist beyond 115 Ma. The research will examine the current distribution of diatoms in fossil material from deep time together with supporting geochemical and geological proxies. The research will also examine other geological formations that may contain diatoms.

Desirable skills and qualifications

The candidate should

• hold a MSc in the geosciences, including Geology, Biogeochemistry, Oceanography or another closely related field.
• have knowledge of geological time scales.
• have practical experience working in a laboratory.
• have practical experience with diatom taxonmy.
• have knowledge of marine diatoms, especially fossil diatoms, would be an assest.
• have the ability to work at other locations (weeks to months) to work with other diatomists.
• be fluent in written and spoken English.
• have good communication skills and the ability to work in a research group (team work), but also independently.

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§.

Your application
Please submit your CV, cover letter and at least two references to former employees/supervisors.
