PhD position Using microfluidics to observe and manipulate coacervate droplets

take place.

What are you going to do?

The de-novo synthesis of life requires integrating the essential features of life, which include replication (the ability to copy oneself), metabolism (promoting the formation of one’s own components from material in the environment) and compartmentalization (keeping the internal components together and separate from the environment) into a system that is maintained out of equilibrium. Key to the creation of a minimal form of life is Darwinian evolution of the resulting synthetic cell-like systems. Serving as the compartments in our work are coacervate microdroplets, consisting of a very dense aqueous phase containing a high concentration of macromolecules. Because coacervates can exist in dilute aqueous phases without loss of droplet structure, they can act as cell-like spheres without the need of a membrane to contain their content.

In this project, you will use microfluidics to create a first-generation platform to achieve growth and division of micrometer-sized coacervate droplets. You will then consider populations of coacervate droplets confined in a second, more complex microfluidic platform, monitoring their growth and mutation rates. “Mother” droplets will be followed alongside their “daughters” using fluorescence microscopy, with addition of precursor materials (“nutrients”) and random removal of individuals (“death”).

Requirements

We are looking for someone who meets the following qualifications:

Essential qualifications

• MSc degree in Biomedical Engineering, Physical or Analytical Chemistry, or related disciplines
• Demonstrated hands-on experience with microfabrication and microfluidics
• Experience with fluorescence imaging
• Enthusiasm, self-motivation, creativity, and team spirit
• Ability to work in a multidisciplinary environment
• Excellent communication skills in English (verbal and written)

Preferred qualifications

• Programming skills (Python, MATLAB, or similar) for data analysis
• Ability to design and implement microcontroller-based control systems (Arduino, Raspberry Pi, etc.)
• Experience with synthetic organic chemistry

Conditions of employment

Fixed-term contract: A temporary full-time (1.0 FTE) position for one year at first with the option of renewal for another three years.

What can you expect from us?

• 232 vacation hours per year, based on a 38-hour workweek (1.0 FTE). You can also work more or fewer hours in exchange for more or fewer free hours. For example, with a 40-hour workweek, you save 96 extra free hours, and with a 36-hour workweek, you lose 96 hours.
• End-of-year bonus of 8.3% and 8% holiday allowance.
• Extensive opportunities for personal and professional development.

Employer

University of Groningen

At the University of Groningen (UG), researchers from all fields of academia and technology are working on academic challenges and societal questions. Lecturers prepare their students for meaningful careers within or outside the academic world. Interdisciplinary research and teaching, sharing of knowledge, collaboration with businesses, government institutions, and societal organizations are aspects that are of the utmost importance to this European top university. The UG aims to be an open academic community with an inclusive and safe working climate that invites you to add your value.

Department

Faculty of Science and Engineering

The Faculty of Science and Engineering (FSE) provides teaching and research across a wide range of disciplines, from physics and biology to artificial intelligence, mechanical engineering, and pharmacy. In close collaboration with partners from industry, healthcare, and society, we contribute to the urgent challenges of our time, such as energy, sustainability, digitization, and medical technology. Our community is open and informal, with more than 7,000 students, 1,000 PhD students, and 1,400 staff members from all over the world. If you would like to learn more about the Faculty of Science and Engineering, visit rug.nl/fse.

You will join the Groningen Research Institute of Pharmacy (GRIP), which is positioned within FSE, and is physically located within the University Medical Centre Groningen (UMCG) of the Faculty of Medical Sciences (FMS). Pharmaceutical research within GRIP is multidisciplinary and bridges clinical and biomedical sciences on the one hand, and chemistry, mathematics, engineering, and physics on the other. The interaction between the pharmaceutical sciences with these fundamental and clinical sciences offers excellent opportunities for cutting-edge research.
