Christoph Müller

ETH Zürich, one of the world's leading universities in science and technology, offers a PhD position in numerical and experimental studies of non-spherical and deformable granular systems. The position is based in the Laboratory of Energy Science and Engineering (D-MAVT), which actively develops advanced tools to probe single- and multiphase granular systems. Granular systems are fundamental to both nature and industry, yet many phenomena such as segregation, surface instabilities, and jamming remain poorly understood. This project specifically investigates how particle deformability and non-sphericity influence the dynamics and rheology of granular systems, with a focus on complex behaviors like transient jamming and stress-induced orientational ordering. The PhD position is part of a collaborative project between the Laboratory of Energy Science and Engineering (Prof. Christoph Müller) and the Institute for Biomedical Imaging Magnetic Resonance Technology (Prof. Klaas Prüssmann). Daily collaboration between PhD students in both groups is expected. The main objectives for the PhD student include advancing numerical tools for modeling non-spherical and deformable granular systems, establishing camera-based experimental techniques such as photo-elasticimetry to determine contact forces and stress fields, and developing machine-learning models to correlate particle deformation and contact forces in 3D systems. Applicants should hold a very good MSc degree in Mechanical Engineering, Physics, or related disciplines. Experience in numerical modeling or imaging techniques is desirable. The ideal candidate is highly motivated, committed, creative, able to work in a team, and possesses excellent communication skills in English. ETH Zürich offers an exciting working environment, opportunities to learn cutting-edge techniques, and perspectives for career development within a diverse and interdisciplinary team. The position is available from July 2026 onwards. ETH Zürich values diversity, sustainability, and an inclusive culture, promoting equality of opportunity and nurturing a respectful environment for all staff and students. Applications must be submitted online via the ETH Zürich application portal, including a motivation letter, CV, transcripts, and names of two potential reference providers. Applications via email or postal services will not be considered.

The Laboratory of Energy Science and Engineering (LESE) at ETH Zürich is offering a fully funded PhD position focused on structure-activity relationships for CO2 capture materials. This research opportunity is part of the National Centre of Competence in Research (NCCR) Separations and aims to advance the fundamental understanding of materials that enable the capture and conversion of CO2. The project integrates process modelling, computational materials screening and discovery, experimental synthesis, and mechanistic and performance assessment under application-relevant conditions for separation technologies. The PhD project will combine the synthesis of model materials, operando characterization, and molecular modelling to identify new CO2 sorbent families and establish structure–performance relationships. Experimental techniques will include operando X-ray absorption spectroscopy, X-ray total scattering, and vibrational spectroscopies. The candidate will work in a top-level research environment with advanced laboratory infrastructure and will have opportunities to learn cutting-edge techniques and develop their research abilities within a diverse and interdisciplinary team. Applicants should hold an excellent MSc degree in Chemical Engineering, Materials Science, or Chemistry, with experience in material synthesis and/or structural material characterization highly valued. The position is available from May 2026 onwards. ETH Zürich values diversity and sustainability, promoting an inclusive culture and equal opportunities for all staff and students. The university is renowned for its excellent education, fundamental research, and direct transfer of new knowledge into society, providing a stimulating environment for over 30,000 people from more than 120 countries. To apply, submit your CV, motivation letter, and transcripts via the ETH Zürich online application portal. Applications sent by email or postal services will not be considered. For further information or questions, contact Dr. Paula Abdala ([email protected]) or Prof. Christoph Müller ([email protected]). For more details about LESE, visit the laboratory's website. This is an exciting opportunity to contribute to climate-neutral solutions and advance your career in materials science and engineering at one of the world’s leading universities.

This PhD position at ETH Zürich's Laboratory of Energy Science and Engineering (LESE) focuses on the development of catalysts for the hydrogenation of CO2 to higher alcohols, such as ethanol. The research aims to advance materials and processes that contribute to efficient and sustainable production of fuels, electricity, and chemicals, with a particular emphasis on closing the CO2 cycle to help societies move towards net zero emissions. The project is funded by the national centre of competence in research (NCCR Catalysis), providing a strong foundation for cutting-edge research. The successful candidate will engage in high-throughput experimentation, synthesis of model catalysts, operando characterization, and molecular modelling to identify novel catalyst families and develop structure-performance relationships. Key experimental techniques include X-ray absorption spectroscopy, X-ray total scattering, and infrared spectroscopy, which will be used to pinpoint catalytically active sites and motifs. Applicants should hold an excellent MSc degree in Chemical Engineering, Material Science, or Chemistry, and have experience in material synthesis and/or structural material characterization. The position offers a stimulating research environment with advanced laboratory infrastructure, opportunities to learn state-of-the-art techniques, and perspectives for career development within a diverse and interdisciplinary team. ETH Zürich is committed to diversity, sustainability, and equality of opportunity, fostering an inclusive culture where all staff and students can thrive. The position is available from January 2026 onwards. Applications must be submitted online through the ETH Zurich application portal, including a CV, motivation letter, and transcripts. For further information, candidates may contact Prof. Christoph Müller or Dr. Paula Abdala.
