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 two
PhD Students
Your tasks
Photochemical processes in 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 use state of the art techniques in trace gas sensing and a novel online aerosol mass spectrometry method but also techniques available at PSI’s large research facilities, such as X-Ray photoelectron spectroscopy and scanning transmission X-Ray microspectroscopy. You will investigate feedbacks between transition metal induced peroxy radical chemistry in aerosol particles with nitrogen oxides, halogen compounds and the organic aerosol composition. You will accompany the experimental activities with modelling tools at various scales including explicit aqueous phase chemistry modelling, modelling of chemistry and diffusional transport in viscous particles and incorporation of specific reactions in a larger scale atmospheric chemistry model. As a PhD candidate you will be enrolled at ETH Zürich.
Your profile
You should have a Master or equivalent in physical, analytical or environmental chemistry. You should bring interest in molecular scale processes of 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.
