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.

For our projects related to atmospheric multiphase chemistry we are looking for a
PhD Student
Your tasks
Photochemical processes in aqueous atmospheric aerosol particles are important for their overall burden and life-time as well as for the gas phase composition and the atmospheric oxidation capacity. You will investigate feedbacks between transition metal induced peroxy radical chemistry with nitrogen oxides, halogen and organic compounds in proxies of aqueous aerosol particles. You will mostly use state of the art techniques in trace gas sensing, but you will also be involved in novel X-Ray photoelectron spectroscopy experiments at the Swiss Light Source (SLS). You will accompany the experimental activities with modelling tools at various scales including explicit aqueous phase chemistry modelling. As a PhD candidate you will be enrolled at ETH Z├╝rich.
Your profile
You should have a Master or equivalent in physical, or environmental chemistry. You should bring interest in a detailed understanding of chemical processes in the atmosphere. You should be motivated to work in an interdisciplinary team.
We offer
Our institution is based on an interdisciplinary, innovative and dynamic collaboration. You will profit from a systematic training on the job, in addition to personal development possibilities and our pronounced vocational training culture. If you wish to optimally combine work and family life or other personal interests, we are able to support you with our modern employment conditions and the on-site infrastructure.

For further information please contact Prof Dr Markus Ammann, phone +41 56 310 40 49.

Please submit your application online by 20 September 2020 (including addresses of referees) for the position as a PhD Student (index no. 5601-00).
