PostDoc - Quantitative modelling of Sperm Dynamics

Post Doc – Quantitative Modelling of Sperm Dynamics

The Post Doc in Quantitative Modelling of Sperm Dynamics will work at Forschungszentrum Jülich and will develop a digital twin of sperm motility, integrating computational simulations with experimental data to create a separation method for advanced semen production.
