Theory and Simulation of Soft Matter, Hydrodynamics, and Biophysics Joost de Graaf

Researcher Profile Joost de Graaf

Currently, I hold an assistant-professor position at the Insitute for Theoretical Physics of Utrecht University. Here, I lead a small group that investigates the influence of (non-Newtonian) hydrodynamics on the behavior of colloidal particles and biophysical systems using analytic theory and numerical methods.

I was previously employed as a Marie Skłodowska-Curie fellow in the group of Prof. Dr. D. Marenduzzo at the University of Edinburgh. There, I worked on understanding the mechanism of self-propulsion of chemically propelled swimmers, as well as the behavior of colloidal gels when incorporating hydrodynamic interactions.

Prior to that, I was a group leader and NWO Rubicon postdoctoral researcher in the Institute for Computational Physics lead by Prof. Dr. C. Holm at the University of Stuttgart. There, my students and I developed lattice-Boltzmann methods for simulating active, self-propelled particles and electrokinetic phenomena.

I started my research career at Utrecht University, where I obtained my PhD in the group of Prof. Dr. M. Dijkstra. My PhD Thesis touched upon predicting crystal structures for faceted and shape-anisotropic particles, the adsorption of such particles to liquid-liquid interfaces, electrostatic screening of Janus particles, and the self-assembly of octapod-shaped nanocrystals. My earliest research was performed under the supervision of Prof. Dr. R. van Roij, with whom I investigated the charging of oil-in-water droplets and the isotropic-nematic phase transition of liquid crystals in an external dipolar field.

Simulating Cilia in the Lung Meike Bos

Meike is funded by a NWO Start-Up grant and falls under my supervision. Meike will study the interaction between cilia and mucus in the lung and how this impacts the airway's antifouling abilities.

Hydrodynamics and Friction for Colloidal Gelation Kim William Torre

William is funded by a NWO Klein (currently M1) grant and falls under my supervision. He will consider the development of a frictional model for interaction between attractive colloids that accounts for rotational and translational immobilization.

Dynamics and Interactions in Growing Bacterial Colonies Jeroen Roberts

Jeroen is a PhD student in my group and also interacts with the group of Farshid Jafarour, a biophysics tenure-track assistant professor at the ITF. He will consider the development a model for growing and interacting bacterial colonies with a specific focus on mechanointeractions.
