The Energy and Process Systems Engineering (EPSE) Group at ETH Zürich is looking for a doctoral student to work on the new generation of prediction methods for the complex fluids and separation processes involved in the solvent-based recycling of plastics.
The EPSE group, led by Prof. Dr. André Bardow, is dedicated to advancing sustainable energy and chemical process systems. Our research spans from the molecular level to the scale of systems. We develop simulation and experimental methods to advance sustainable energy and chemical processes from the molecular to the system scale.
Project background The vision of our recently funded ERC Advanced Grant DISC3Lab is to devise a validated discovery loop for sustainable chemical processes, targeting the solvent-based recycling of plastics. Chemical recycling is a key element of a transition towards a chemical industry within the Planetary Boundaries. However, the current process design paradigm is too slow, labor-intensive, and fragmented between disciplines.
We aim to overcome these bottlenecks to accelerate the development of sustainable processes. For this purpose, this project will develop predictive models, ranging from the basis in thermodynamic mixture properties to conceptual process design for chemical plastics recycling, by linking advanced machine learning techniques with high-throughput experimental methods developed by other team members.
Job description
- Your main task will be to advance thermodynamically consistent prediction methods for fluid properties and/or separation processes by developing new, more general, and more reliable hybrid thermodynamic and data-driven predictive models
- The methods developed in this project will overcome current limitations in training data sparsity, quantification of model uncertainty, and poorly specified mixtures or separation processes
- The work will be conducted in tight integration with a companion doctoral candidate who will focus on advancing the experimental counterpart methods
- Your role will also involve mentoring and co-supervising student projects and theses
- Additionally, you will engage in various group and institute duties and activities
- As an integral partof your work, you will publish your results in peer-reviewed journals and present them at international conferences
Profile
- You meet the requirements for a doctoral program at ETH Zurich and have an excellent Master's or diploma in chemical engineering, process engineering, mechanical engineering, energy science & technology, physical chemistry, or a related field
- Ideally, you already have experience in ML and methods to predict thermophysical properties and/or conceptual process design
- The ability to work independently and excellent communication and writing skills in English complete your profile
We offer We offer a full-time position for the duration of your doctoral studies, starting upon agreement with the earliest starting date of October 1st, 2026. We are
providing a supportive environment that fosters professional and personal growth. You will join a dynamic, motivated, and interdisciplinary team of researchers with expertise in thermodynamics, process design, energy system optimization, and life cycle assessment, working collaboratively with research and industry partners. You will work in an inspiring, collaborative environment to address critical global challenges.
