PhD Candidate in Predicting Thermodynamics and Processes for Circular Carbon Plastics / PhD Candidate in Predicting Thermodynamics and Processes for Circular Carbon Plastics

PhD Position in Predicting Thermodynamics and Processes for Circular Carbon Plastics

100%, Zurich, fixed-term

The Energy and Process Systems Engineering (EPSE) Group at ETH Zürich is seeking a doctoral student to work on the next generation of predictive methods for the complex fluids and separation processes involved in the solvent-based recycling of plastics.

Led by Prof. Dr. André Bardow, the EPSE group is committed to advancing sustainable energy and chemical process systems. Our research spans from the molecular level to the system scale, where we develop simulation and experimental methods to enhance sustainable energy and chemical processes.

Project Background

The vision of our recently funded ERC Advanced Grant DISC3Lab is to establish a validated discovery loop for sustainable chemical processes, targeting solvent-based recycling of plastics. Chemical recycling is crucial for transitioning towards a chemical industry that operates within planetary boundaries. However, the current process design paradigm is often slow, labor-intensive, and fragmented across various disciplines.

We aim to address these challenges to accelerate the development of sustainable processes. This project will focus on developing predictive models, integrating thermodynamic mixture properties with conceptual process design for chemical plastics recycling through advanced machine learning techniques and high-throughput experimental methods.

Job Description

• Your primary responsibility will be to advance thermodynamically consistent prediction methods for fluid properties and separation processes by creating new, general, and reliable hybrid thermodynamic and data-driven predictive models.
• The methods developed in this project will tackle current limitations regarding training data sparsity, model uncertainty quantification, and poorly specified mixtures or separation processes.
• You will work closely with a companion doctoral candidate focusing on advancing the experimental counterpart methods.
• Your role will also involve mentoring and co-supervising student projects and theses.
• Additionally, you will participate in various group and institute duties and activities.
• As part of your work, you will publish your findings in peer-reviewed journals and present them at international conferences.

Profile

• You meet the requirements for a doctoral program at ETH Zurich and possess 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 machine learning and methods for predicting thermophysical properties or conceptual process design.
• Your ability to work independently, along with excellent communication and writing skills in English, will be essential.

Workplace

Our workplace offers an inspiring, collaborative environment to tackle critical global challenges. You will join a dynamic, motivated, and interdisciplinary team of researchers specializing in thermodynamics, process design, energy system optimization, and life cycle assessment. The role includes opportunities for group discussions and collaborative efforts ranging from molecular level studies to system scale analyses.

What We Offer

We provide a full-time position for the duration of your doctoral studies, starting upon agreement with the earliest starting date of October 1st, 2026. Our supportive environment fosters both professional and personal growth. You will gain access to state-of-the-art laboratory facilities and experimental setups, enabling impactful research. This position will also help develop your critical thinking, data analysis, problem-solving, and project management skills while contributing to the wider academic community through publications and presentations at leading conferences.

We Value Diversity and Sustainability

ETH Zurich is committed to promoting an inclusive culture, valuing diversity, and nurturing a working and learning environment that respects the rights and dignity of all staff and students. We strive for equality of opportunity and sustainability as core values, consistently working towards a climate-neutral future.
