Particle sorting and separation

• Sorting and separating particles based on their intrinsic properties (e.g. size or deformability) is important for the diagnosis of diseases. My PhD students and I use computer simulations to better understand those separation mechanisms.
• Recent publication: Breakdown of deterministic lateral displacement efficiency for non-dilute suspensions: a numerical study

Blood flow and blood cell dynamics

• Blood is clearly one of the most important fluids in the human body. It transports oxygen and nutrients to all cells in the body. It is also related to a number of diseases, such as malaria or blood clotting disorders. Understanding how red blood cells deform and how platelets initiate the clotting process is key to the development of novel disease diagnostics and treatments.
• Recent publication: Effect of tube diameter and capillary number on platelet margination and near-wall dynamics

Suspension rheology

• The rheology of dense suspensions strongly depends on the particle properties, volume fraction and confinement. I am interested in understanding the mechanisms affecting the viscosity of dense suspensions.
• Recent publication: Fluctuations and diffusion in athermal suspensions of deformable particles

Lattice-Boltzmann method

• The lattice-Boltzmann method is a relatively new approach to solve the Navier-Stokes equation; but it can do much more than that. There is still an active research interest and method development, and the number of applications where the lattice-Boltzmann method plays a role is constantly increasing.
• Recent publication: A Ternary Free Energy Lattice Boltzmann Model with Tunable Surface Tensions and Contact Angles
