PhD Student - Electron transfer processes at clay minerals

Description du poste

## Your tasks ## * You will conduct laboratory experiments on redox process of iron-bearing clay minerals. This will involve investigations of electron transfer reactions to and from clay mineral iron with the help of kinetic experiments, spectroscopies, and a range of complementary aqueous and solid phase analyses (e.g., HPLC, XRD, Mössbauer spectroscopy, electron microscopy, electrochemical methods). * You will actively participate and collaborate in the larger research project (SNSF funded) on electron transfer at clay minerals. This will include collaboration with national and international team members and a research stay of up to 6 months in the laboratory of the collaborator Prof. Chris Gorski at Penn State University, USA, to conduct electrochemical experiments. * You will assess and interpret the data collected, communicate your results at conferences and in the form of publications in peer-reviewed journals, and write a PhD thesis to complete your studies. ## Your profile ## * You hold a master-s degree in chemistry, geosciences, environmental sciences, or a closely related field. * You are highly motivated to conduct laboratory work and have prior experience in working in a chemical laboratory environment. * Experience in aqueous and solid phase analyses (e.g., HPLC, XRD, Mössbauer spectroscopy, electron microscopy) is advantageous. * You have excellent communication and time management skills. * You are excited to work in a multidisciplinary team and are willing to spend up to 6 months abroad (Penn State University, USA) for a specific part of your PhD project. * In this international project team, excellent knowledge of English is essential, and the ability to communicate in German is an advantage. ## 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.  You will be enrolled at the University of Bern.
