PhD Position Experimental Fluid Dynamics of Microalgae Suspensions

Published Deadline Location
15 Mar 26 Apr Delft
Are you interested in new problems at the interface between fluid dynamics and biology? Are you excited about hands-on experimental work in a multidisciplinary environment? We are looking for an enthusiastic PhD candidate to develop new experiments to track microbial life in flows.

Job description

Photosynthetic microalgae hold promise for the sustainable production of high-value products, bioplastics, biofuels, and future engineering living materials. Flowing suspensions of living microalgae cells represent a new kind of living fluid that physiologically responds to the environment and flow conditions. New insight into the flow dynamics of these living microalgae suspensions is crucial to model algae blooms or develop new flow technologies for bioreactors.

The Ph.D. position is available within the project “Flow4Algae”. This experimental project aims to understand the multiscale fluid dynamics of living microalgae suspensions. We are particularly interested in the interplay between flow conditions, cell physiology, and cell growth. Each different project will focus on flow conditions ranging from linear shear flows in microfluidics to weak turbulence. In this project, you will design new multiscale experiments and analytical tools for the different flow regimes. These studies will be conducted in the BioFluids Laboratory in TU Delft and will use the infrastructure in the laboratory, including advanced flow diagnostics (Particle Image Velocimetry, Particle Tracking Velocimetry, and Laser Induced Fluorescence), microscopy (3D tracking multi-view microscopy and Fluorescence), rheology tools, microfluidics, and existing flow dynamics setups.

As a Ph.D., you will be part of a vibrant team of researchers working on the project Flow4Algae, with diverse backgrounds and expertise. The group is part of the Process & Energy Department, which thrives to conduct world-class research & education focusing on process & energy technologies for sustainable development.
