Your Job:
This work will be performed as part of an agile team unified by a common goal:
An Industry partner from semen production provides fresh sperm cells and pre-analysis. A second industry partner from data sciences provides data management and AI based Image analysis, an internal experimental group, and an internal simulation-sciences group (You+Supervisor+support by lab). These collaborations enable practically relevant and breakthrough results.
This team goal requires a quantitative model describing and predicting sperm motility under various conditions. You will develop the digital twin of sperm motility, and utilize it to develop a separation method. Your tasks will include:
- Performing computer simulations and matching them to experimental data
- Very close collaboration with experiments, including occasional wet lab work
- Merging experimental results, simulations, and literature for optimal conditions inducing movement differences, in collaboration with the team.
- Participation in conferences in Germany and abroad (incl. presenting your research results)
- Travel to industry partners to learn and set up on-site research
- Preparing scientific publications and project reports
Your Profile:
- Strong motivation for an interdisciplinary project that combines physics and biology together with simulation and data science and practical relevance
- A master`s degree or diploma and subsequent PhD in biophysics, biology, biochemistry, or other relevant discipline
- Excellent written and spoken English skills
- High degree of independence and commitment
- Good knowledge of python and C++
- Experience in relevant work tasks are advantageous but not mandatory:
Simulation sciences, ideally modelling microswimmers, Wet-Lab work, Different forms of microscopy
