Position: Postdoctoral Fellow
Institution: Paul Scherrer Institut
Department: Analytical Chemistry Research Group
Location: Villigen, Aargau, Switzerland
Duties: The impact of aerosols on climate remains poorly constrained, leading to considerable uncertainties in predicting the climate sensitivity to greenhouse gases. A large fraction of these uncertainties is due to our deficient knowledge of the composition and magnitude of natural emissions before 1750, especially for organic aerosols, forming 20-70 % of today’s fine particulate matter. You will determine the chemical composition and sources of organic aerosols in the pre-industrial and industrial atmosphere by analyzing molecular markers in ice cores from Europe and the Central Asian Altai, applying sensitive liquid chromatography coupled to electrospray ionization ultrahigh resolution mass spectrometry
Requirements: You hold a PhD degree in chemistry, environmental sciences, physics or a related field. You have a strong background in organic mass spectrometry. As a team player you enjoy working in an interdisciplinary, multinational research environment
   
Text: The Paul Scherrer Institute PSI is the largest research institute for natural and engineering sciences within Switzerland. We perform cutting-edge research in the fields of matter and materials, energy and environment and human health. By performing fundamental and applied research, we work on sustainable solutions for major challenges facing society, science and economy. PSI is committed to the training of future generations. Therefore about one quarter of our staff are post-docs, post-graduates or apprentices. Altogether PSI employs 2100 people.
