The Laboratory of Energy Science and Engineering (LESE, ETH Zürich) invites applications for a PhD position in the field of CO₂ capture and critical element recovery, with a focus on atomic-scale structure–performance relationships in separation materials. This PhD position is funded by the National Centre of Competence in Research (NCCR) Separations, and is carried out under the co-supervision of Dr. Paula Abdala and Prof. Christoph R. Müller.

The aim of this project is to establish a fundamental understanding of how atomic structure governs selectivity, capacity, and stability in materials for CO₂ capture and for the recovery of valuable elements such as lithium and cobalt from complex waste streams. These applications are key to enabling sustainable carbon management and circular resource use.

• The research combines the synthesis of model materials with advanced structural and spectroscopic characterization, with a strong emphasis on X-ray Absorption Spectroscopy (XAS), X-ray total scattering with pair distribution function analysis, and vibrational spectroscopy
• These techniques will be used to probe local coordination environments, electronic structure, and structural dynamics under working conditions.
• The project is embedded in a highly interdisciplinary environment, linking experimental materials chemistry with computational screening and process modelling
• The overarching goal is to connect atomic-scale mechanisms directly to their separation performance and to derive rational design principles for improved materials

• Excellent MSc degree in Chemical Engineering, Materials Science, Chemistry, or related field
• Experience in materials synthesis and characterization is an advantage
• Strong motivation, creativity, and ability to work independently and in teams
• Interest in atomic-scale mechanisms in separation materials
• High degree of independence and self-organization
• Willingness to work in an interdisciplinary and evolving research project
• Flexibility for intensive experimental campaigns, including synchrotron beamtime

• An exciting working environment
• Opportunities to learn cutting edge techniques
• Perspectives for career development
• A diverse and interdisciplinary team

We look forward to receiving your online application with the following documents:

• CV
• Motivation letter
• Transcripts
