Freie Uni­ver­si­tät Ber­lin - Fachbereich Biologie, Chemie, Pharmazie - Institut für Chemie und Biochemie GRK2662 – AG Weinhart (International Research Training Group GRK2662)

The DFG-funded international Research Training Group GRK2662 "charging into the future:
understanding the interaction of polyelectrolytes with biosystems" aims to gain a better
understanding of the molecular interactions between polyelectrolytes such as DNA, proteins
or heparin with complex biological systems. A special feature of the Research Training
Group is the close, complementary cooperation between scientists from Freie Universität
Berlin (Germany), McGill University, Montréal, and the University of British Columbia,
Vancouver (Canada).
The international research training group GRK2662 offers

  • positions for research assistants with the possibility of a doctorate,
  • structured academic training in an international research environment, including
    participation in a variety of research-specific and career-enhancing training courses and
  • integration into an interdisciplinary international research network,
  • and the opportunity for research stays in the laboratories of the Canadian partner

Research assistant (Praedoc) (m/f/d)

with 67%-part-time job
limited to 31.03.2026
salary grade (Entgeltgruppe) 13 TV-L FU
reference code: 2024_grk2662_PhD_C1

Working field:

In subproject C1, interactions of polyelectrolytes with blood and the endothelial glycocalyx
are investigated. Within the project of Prof. Dr. Marie Weinhart, a cell-based, dynamically
cultivated in vitro model of the endothelial glycocalyx is being developed, which enables the
systematic investigation of electrostatic interactions with synthetic polymers and blood cells.
Tasks include the synthesis and analysis of cationic model polymers (NMR, DLS, zeta
potential) and interaction studies in flow chamber experiments (TIRF, LCSM,
immunofluorescence, ELISA). Further project information can be found at


Completed university degree (M.Sc. or Diploma degree in) biotechnology, biochemistry,
chemistry, biophysics or related subjects.


  • Applicants should fulfill the requirements for admission to the doctoral program of the
    Department of Biology, Chemistry and Pharmacy at Freie Universität Berlin.
  • Comprehensive theoretical knowledge and practical experience in mammalian cell culture
    techniques including relevant analytical techniques
  • Practical experience in the field of dynamic cell cultivation (micro-/millifluidics)
  • Background in cell biology and protein biochemistry
  • Basic knowledge of (bio)polymer chemistry, synthesis/modification and analytics
  • Basic knowledge of natural and synthetic biomaterials
  • Basic engineering knowledge (e.g. CAD design, CFD simulations) is advantageous
  • High motivation to work independently and scientifically
  • Very good written and spoken English skills
  • Good communication skills and willingness to work in collaborations and teams

How to apply:

We look forward to receiving your application, which should include the following documents:

  • A one-page letter of motivation why you want to work in Project C1, together with details of
