PhD position in atmospheric chemistry with focus on organic matter in aerosols and their role in formation of Arctic clouds
Department of Meteorology , Stockholm University, Sweden
Ref. No. SU FV-0996-17
At the Department of Meteorology at Stockholm University (MISU) we conduct research and education in an international environment within four main areas: Chemical and Dynamic meteorology, Atmospheric physics, and Physical oceanography. In all these areas there is a strong focus on the climate and on processes important for the climate and its development. The department employs some 65 individuals, of which about 30 are scientists, 20 PhD students and 15 in the administration and the technical support. The department is part of the Bolin Centre for Climate Research, www.bolin.su.se, and together with three other departments at the university cover research of most of the important aspects of the climate system.

The Arctic climate is changing faster than anywhere else on Earth. One of the most obvious consequences of this warming is rapidly diminishing sea-ice, especially in late summer. The observed dramatic loss of summer sea-ice must have strong consequences for marine life thriving in ice-free conditions and on nutrients freed from the melting ice. Particulate and gaseous emissions from Arctic microbiological marine processes may affect the widespread blanket of low clouds through their role in forming the cloud droplets over the summer Arctic, which in turn affects the melting of sea ice. Understanding this two-way connection between the sea and the clouds is necessary for the projection of the development of Arctic climate and its influence on human activities.
The proposed project aims at understanding the connections between biological processes in the Arctic seas and the overlying clouds that are known controllers of regional climate and sea-ice. The research work will include the development and deployment of different techniques such as liquid and gas chromatography, and electron microscopy to characterize the chemical and physical properties of aerosol particulate matter, its state of mixture, sources and partitioning between air and the surface ocean. In particular, chemical analyses will focus on the detection of organic compounds such as polysaccharides, proteins, and amino acids in samples to be collected during a scheduled icebreaker expedition to the North Pole in the summer of 2018. Experience in experimental work, and analytical or organic chemistry would therefore be an advantage.
In order to meet the general entry requirements, the applicant must have completed a second-cycle degree, completed courses equivalent to at least 240 higher education credits, of which 60 credits must be in the second cycle, or have otherwise acquired equivalent knowledge in Sweden or elsewhere.
In order to meet the specific entry requirements, the general syllabus for doctoral studies in the field of meteorology stipulates that at least 90 points must be in one of the subjects meteorology, oceanography, physics or chemistry, at least 15 points must be in mathematics, and an independent project work corresponding to at least 15 points must have been completed. The requirements can also be met by acquiring the corresponding knowledge in some other way, in Sweden or abroad. Only a person who will be or has already been admitted to a third-cycle program may be appointed to a doctoral studentship. The primary assessment criteria in appointing a doctoral student should be the capacity to benefit from the training.
The selection among the eligible candidates will be based on their capacity to benefit from the training. The following criteria will be used to assess this capacity: the candidates' documented knowledge in a relevant field of research, written and oral proficiency in both Swedish and English, the capacity for analytical thinking, the ability to collaborate, as well as creativity, initiative, and independence. The assessment will be based on previous experience and grades, the quality of the degree project, references, relevant experience, interviews, and the candidate's written motivation for seeking the position. Admission Regulations for Doctoral Studies at Stockholm University are available at: www.su.se/rules.
Terms of employment
The term of the initial contract may not exceed one year. The employment may be extended for a maximum of two years at a time. The total period of employment may not exceed the equivalent of four years of full-time study.
Doctoral students should primarily devote themselves to their own education, but may also engage in teaching, research, and administration corresponding to a maximum of 20% of a full-time position.
Please note that admission decisions cannot be appealed.
Stockholm University strives to be a workplace free from discrimination and with equal opportunities for all.
