PhD Candidate / PhD Candidate

PhD Position in Automated Laboratory for Plastic Recycling

Details

100%, Zurich, fixed-term

The Energy and Process Systems Engineering (EPSE) Group at ETH Zürich is seeking a doctoral student to conduct experimental characterization of the thermophysical properties and separation processes involved in recycling complex fluids derived from plastics.

Led by Prof. Dr. André Bardow, the EPSE group is dedicated to advancing sustainable energy and chemical process systems. Our work spans from the molecular level to system-scale applications, developing simulation and experimental methods to enhance sustainable processes.

Project Background

The vision of our recently funded ERC Advanced Grant DISC3Lab is to create a validated discovery loop for sustainable chemical processes, focusing on solvent-based recycling of plastics. This project will contribute towards developing a Thermodynamic & Process Lab-on-a-chip, establishing an automated small-scale experimental platform that provides high-throughput measurements of fluid properties critical for the design of recycling processes. For instance, this includes determining the vapor-liquid equilibrium curve for recyclate mixtures designated for distillation fractionation.

The data generated will inform and validate the predictive numerical methods being developed by other team members. Our approach tackles the challenges of traditional experiments which are often too costly and time-intensive for rapid process design, by merging microfluidics with laser spectroscopy to explore complex phenomena like multi-component phase equilibria and reaction dynamics.

Job Description

• Your primary responsibility will be designing, setting up, and performing novel experiments using microfluidics, spectroscopy, and algorithm-driven lab automation for closed-loop, self-optimizing experiments.
• Initial experiments will focus on examining phase equilibria and transport processes in liquid mixtures.
• You will collaborate closely with a fellow doctoral candidate dedicated to advancing predictive simulation methods.
• Your role will also include mentoring and co-supervising student projects and theses.
• Engagement in various group and institute duties and activities will be expected.
• Your results will contribute to peer-reviewed journals and be presented at international conferences.

Profile

• You have the qualifications necessary for a doctoral program at ETH Zurich, and possess an outstanding Master's degree or diploma in chemical engineering, process engineering, mechanical engineering, energy science & technology, physical chemistry, or a related field.
• Experience in experimental work, including setting up experiments and utilizing microfluidics and spectroscopy is highly desirable.
• You have a keen interest and capability to develop model-based methods for experimental design and analysis. You are motivated to learn and apply modern experimental and simulation techniques.
• Your ability to work independently, along with excellent communication and writing skills in English, complements your profile.

Workplace

At ETH Zurich, we offer a supportive environment conducive to both professional and personal growth. You will be part of a dynamic and interdisciplinary team of researchers specializing in thermodynamics, process design, energy system optimization, and life cycle assessment. This collaboration will allow you to address critical global challenges within an inspiring and cooperative atmosphere. Opportunities for engaging in group discussions and collaborative efforts from molecular levels to systems scale will provide insights into various methods and approaches.

We Offer

This full-time position will span the duration of your doctoral studies, commencing upon mutual agreement with an earliest start date of October 1st, 2026. You will have access to state-of-the-art laboratory facilities and experimental setups, facilitating impactful research and fostering the development of critical thinking, data analysis, problem-solving, and project management skills.
