The PhD candidate will join the 5-year EcoDropLab project, developing sustainable droplet-based microfluidics platforms for biological and environmental research, especially microplastic-related microbial processes. Research includes bacterial aggregation, biofilms, antimicrobial resistance, and screening antimicrobial compounds using microfluidics, lab-on-a-chip systems, microscopy, and materials science in an interdisciplinary, international environment.
The PhD candidate will join the 5-year “EcoDropLab” project, which focuses on developing a sustainable and accessible droplet-based microfluidics platform for biological and environmental research, with a particular focus on microplastic-related microbial processes. This includes studying how microplastics influence bacterial aggregation, biofilm formation, and antimicrobial resistance, as well as enabling screening of antimicrobial and antibiofilm compounds. The project combines a wide range of approaches, including droplet-based microfluidic workflows, 3D-printed lab-on-a-chip systems, experimental work in biology and chemistry, microscopy-based analysis, and materials science aspects related to microplastics and device development. Within this framework, the candidate will contribute to selected aspects of the project and have the opportunity to shape their research direction based on their background and interests. The candidate will work in an interdisciplinary environment combining microbiology, chemistry, engineering, and materials science, collaborating across departments and with international partners.
Responsibilities and foreseen tasks:
The PhD project is embedded within the broader EcoDropLab framework and encompasses several research directions. Depending on the candidate’s background and interests, potential foreseen tasks include:
Development of sustainable and user-friendly droplet-based microfluidic technologies for biological and environmental applications
Investigation of microbial processes, including bacterial aggregation, biofilm formation, and antimicrobial resistance, in relation to microplastics
Screening and evaluation of antimicrobial and antibiofilm compounds using microfluidic approaches
Design and development of lab-on-a-chip systems, including 3D-printed devices, and their integration into experimental workflows
Materials science related to microplastics and microfluidic device development
Prospective candidates are encouraged to contribute to and help shape the research direction within the overall objectives of the EcoDropLab project.
Applicants should fulfil the following requirements:
A master’s degree in a relevant field (e.g. biotechnology, microbiology, chemistry, materials science, or a related discipline)
Experience with basic laboratory work and experimental techniques
Clear interest in the highly interdisciplinary research topic of the position
Ability to work both independently and as part of an international and collaborative research team
Strong analytical thinking and problem-solving skills
Good written and oral communication skills in English
The following experience is beneficial:
Experience with microfluidics (especially droplet-based systems)
Background in biofilm research, antimicrobial resistance, and/or microplastic-related studies
Experience with 3D printing, materials science, or device fabrication
Experience with microscopy and/or image analysis
Experience with data analysis or basic programming skills
