|Postdoctoral fellow in Atmospheric chemistry at the University of Gothenburg - Deadline: 31st of May 2017
Research group : Atmospheric science, Professor Mattias Hallquist (email@example.com), University of Gothenburg
Specific subject description : The aim of this project is to quantify, understand and provide tools to describe atmospheric oxidation of organic compounds. This oxidation is important to understand formation of secondary organic aerosol (SOA) but also the generally production of oxygenated compounds that can effect air quality both in outdoor and indoor environments. Aerosol particles are crucial components in any evaluation process regarding air quality and climate change. SOA represents a significant fraction of the tropospheric aerosol. Still, the current level of understanding of SOA processes is remarkably low compared to other processes in aerosol science, i.e. modelled SOA based on experimental findings and existing theory does not capture the variability of observed SOA loadings and often predicts far less SOA than observed. It has been indicated that biogenic SOA can be largely affected by anthropogenic pollutants, i.e. NO2, SO2 or organic compounds e.g. aromatics and aldehydes. The effect of anthropogenic pollutants may explain part of the discrepancy between models and field observations. Specifically, this project applies high resolution mass spectroscopy techniques for detailed analysis of gas and particle phase to elucidate chemical mechanisms of importance for atmospheric SOA. A specific aim is how to link SOA mechanisms to model developments for descriptions in air quality and climate models.
The experiments will primarily be conducted using our high-resolution time-of-flight chemical-ionization mass spectrometer in combination with inlets separating particle and gas phase for characterization of organic compositions. (FIGAERO-CIMS)
Job assignments : Research in atmospheric chemistry using high resolution mass spectrometry with chemical ionization. The experimental studies can be carried out both in our laboratory but also in the field to study the emissions and secondary transformation of organic compounds in both indoor and outdoor environments. In addition to work in Sweden one is expected to participate in our international collaboration projects, currently with emphasis on India, China, Germany and the UK. The work involves a great deal of analysis and evaluation of measurement data for the understanding and quantification of atmospheric oxidation of organic substances.
Eligibility : The qualifications for academic positions are given in Chapter 4, Section 3 - 4 of the Higher Education Ordinance.
To qualify as a postdoctoral fellow, the applicant must have completed a doctoral degree corresponding to a Swedish doctoral degree.
Preference will be given to candidates who have been awarded the degree no more than three years before the application deadline Applicants with a degree obtained earlier than the stipulated three years may be preferred if special reasons exists. Special reasons in this context include, but are not limited to, leave due to illness and parental leave.
A requirement is experience in mass spectroscopy with atmospheric application demonstrated by international publications in peer-reviewed journals and experimental work.
Preferences will be given to candidates that have experience in working with a high-resolution time-of-flight chemical-ionization mass spectrometer (HRToF-CIMS), where also previous experience on air quality studies in Beijing or Hong Kong are beneficial.
Assessment : Regulations for the evaluation of qualifications for academic positions are given in Chapter 4, Section 3 - 4 of the Higher Education Ordinance.
Experience in working with a high-resolution time-of-flight chemical-ionization mass spectrometer (HRToF-CIMS) with applications on atmospheric chemistry. Previous experience on air quality studies in Beijing or Hong Kong.
The research group : Our atmospheric science constellation is unique in Sweden in that it takes a molecular approach to transport and reaction processes in the atmosphere. A unifying focus is the study of aerosols, with activities ranging from fundamental studies of chemical reactions on the molecular level, to applied work including field studies of atmospheric processes, their importance to current climate and air quality research. The research contributes to developments in the fields of colloidal chemistry, nanotechnology, medicine as well as development of traffic related chemistry and sustainable development in developing countries.

|Research Fellow in Air Pollution at the air pollution/atmospheric chemistry research group at the University of Birmingham - Deadline: 8th of May 2017
Applications are invited for a 36 month Postdoctoral Research Fellow post in Birmingham, to participate in field measurement campaigns in Delhi, and to carry out offline physical and chemical analyses of airborne particles collected using a number of analytical approaches such as Nanoscale Secondary Ion Mass Spectrometer, Transmission Electron Microscope and Gas Chromatography-Mass Spectrometer. The offline data will be integrated with other online and semi-online analyses (e.g., size distribution, metal, isotope and Aerosol Mass Spectrometer data) to understand the sources of PM2.5 and the formation mechanisms of haze particles under different atmospheric conditions (e.g., winter vs. summer, fog vs. non-fog).
Delhi is one of the world’s most polluted cities, with millions of inhabitants experiencing air pollution which substantially exceeds national and international standards. Research to identify sources and process responsible for poor air quality in Delhi is urgently needed, to support the development of efficient policies reduce pollution levels and improve human and environmental health.
The UK Natural Environment Research Council, in collaboration with Indian funders, have developed the research programme “Atmospheric Pollution and Human Health in an Indian Megacity (APHH-India)” with a view to generating both a better understanding of the air pollution phenomena in Delhi and surrounding areas and the options for mitigation. The University of Birmingham leads the “An Integrated Study of Air Pollutant Sources in the Delhi National Capital Region (NCR): ASAP-Delhi” project within this programme; ASAP-Delhi will support a range of measurement and modelling activities conducted by the Universities of Birmingham and Surrey in the UK, and by the Indian Institute of Technology (Delhi) and National Physical Laboratory in Delhi.
The applicant will join the air pollution / atmospheric chemistry research group at the University of Birmingham, with field, laboratory and model activity ranging from source and emissions measurements to model and experimental studies of vegetation - climate interaction. They will have the opportunity to interact with the wider group, and to contribute to PhD and Masters student supervision For more information click here: http://www.birmingham.ac.uk/research/activity/environmental-health/index.aspx
