Interfacial flows in evaporating liquid droplets can form remarkably rich and complex deposition patterns of suspended microparticles or polymers. In this PhD project we will unravel how the flows inside an evaporating multi-component droplet cause the spontaneous aggregation of the biopolymer collagen into beautifully hierarchically ordered patterns. To this end, we will employ a combination of theoretical and numerical modelling, both on the molecular and the continuum scale. We will complement the modelling approach by laboratory experiments, using state-of-the-art imaging techniques. The output of the project will be a detailed understanding of collagen pattern formation in evaporating drops, and a practical method to generate a library of well-controlled collagen patterns. In collaboration with researchers at the department of Biomedical Engineering, we will use these collagen platforms to study the behavior of cells in healthy and pathological settings and exploit their use for tissue engineering applications.

The project will be carried out in the team of Dr. Hanneke Gelderblom, assistant professor in the Fluids and Flows group at the department of Applied Physics. The team focusses on the physics of interfacial flow phenomena. The PhD project will be embedded within the Immuno-engineering program of the Institute of Complex Molecular Systems (ICMS). Within the project you will closely collaborate with the Soft Matter and Biological Physics group within the department of Applied Physics and with researchers from Orthopaedic Biomechanics group in the department of Biomedical Engineering. You will also contribute to education in the Applied Physics department. Apart from supervising BSc and MSc students in their research projects, other assistance in education, e.g. in bachelor courses, is usually limited to about 5% of your contract time.
