The Department of Animal Ecology, Evolution and Biodiversity at the Faculty of Biology and Biotechnology is looking for a 

PhD student (m,f,x) for 3 years with 25,8895 hours per week, TV-L E13

The Department of Animal Ecology, Evolution and Biodiversity within the Faculty of Biology and Biotechnology at the Ruhr University Bochum has a major research focus on the eco-evolutionary basics of phenotypic plasticity. For example, the prerequisites and mechanisms relevant for the development of phenotypically plastic traits and their function in the reduction of predation are key aspects of our work. By comparing different systems, we get insights into the ecology and evolution of phenotypic plasticity.

The DFG-funded project “Hydrodynamics of diverse inducible morphological defences in the model organism Daphnia: effects, costs and benefits” investigates the hydrodynamic properties of inducible defences of Daphnia against different predators.
Therefore, you will induce the respective morphological defences in various Daphnia species.
You will visualize and measure these defences three-dimensionally using state-of the-art imaging and then simulate effects of changes in morphology and potential alterations of swimming behaviour using computational fluid dynamics (CFD). Furthermore, you will analyse the observed morphological and behavioural alterations statistically using the programming language R.
The results shall be visualized and published in peer-reviewed journals.

extent: part-time
duration: temporary
beginning: as soon as possible

Your profile:

  • very good to good Master’s degree/diploma in biology, ecology, physics or similar
  • experience in the planning, execution and evaluation of laboratory experiments, especially in the generation and evaluation of fluid mechanical data
  • knowledge and experience with programming languages (especially R/Matlab) and corresponding statistics
  • general enjoyment of working with PCs and persistence in solving problems
  • knowledge and experience with the model organism Daphnia is helpful
  • experience in the creation of scientific figures and texts is an advantage

Our offerings:

  • challenging and varied tasks with a high degree of personal responsibility

The Ruhr-Universität Bochum is one of Germany’s leading research universities, addressing the whole range of academic disciplines. A highly dynamic setting enables researchers and students to work across the traditional boundaries of academic subjects and faculties. To create knowledge networks within and beyond the university is RUB’s declared aim.

The Ruhr-Universität Bochum stands for diversity and equal opportunities. For this reason, we favour a working environment composed of heterogeneous teams, and seek to promote the careers of individuals who are underrepresented in our respective professional areas. The Ruhr-Universität Bochum expressly requests job applications from women. In areas in which they are underrepresented they will be given preference in the case of equivalent qualifications with male candidates. Applications from individuals with disabilities are most welcome.
