Read about the advertisement and apply for the job here: PhD Research Fellow in Experimental Fluid Mechanics: Tunable hairy surfaces for droplet flow control (280936) | University of Oslo
Deadline: 9 June 2025
About the position
A PhD Research Fellowship is available at the Department of Mathematics in the research group of Prof. Andreas Carlson at the University of Oslo (UiO).
No one can be appointed for more than one PhD Research Fellowship period at the University of Oslo.
Starting date as soon as possible and preferably by October 1st, 2025.
The fellowship period is 3 years.
The position is part of the HAIRY project funded by the Research Council of Norway.
The project aims to provide a fundamental understanding of the physical processes involved as droplets interact with soft, hairy surfaces. Essential to the project is the development of a new understanding of elastocapillary flow, which refers to the interaction between capillary forces and the elastic deformations of the soft, hair-like structures covering surfaces.
The PhD research fellow will conduct fluid mechanics experiments and develop methodologies for manufacturing soft, hairy surfaces.
Surfaces densely covered with soft, slender fibers, akin to a shag carpet, that come into contact with a liquid interface are abundant in biology and relevant for a wide range of engineering processes. These hairy surfaces exhibit unique properties and can: enable the removal of particles and pathogens when raindrops slide on plant leaves, produce cilia-driven liquid or cellular transport in our bodies, facilitate drinking in animals, assist in the removal of water drops on insects, provide liquid and thermal transport on feathers, and give fur drag-reducing properties, to name just a few examples.
The project aspires to generate a new fundamental understanding of droplet flow on hairy surfaces and create pathways for engineering these surfaces for droplet flow control, both through passive designs and active surface reorganization.
You will work with
The PhD student will:
- Develop droplet flow experiments
- Develop a methodology for making soft hairy surfaces
- Be directly involved in integrating experiments and theoretical prediction
- Develop independence and be self-driven to advance with their research project
- Work in an interdisciplinary team with expertise in mechanics, complex fluids, physics and biophysics and sustainability thinking
- Follow our PhD program that include an educational component
This is the right position if you are highly motivated about fundamental science and excited about questions related to fluid flows, droplets, wetting and interfacial fluid mechanics.
The PhD research fellow will join an international and interdisciplinary research group lead by Prof. Andreas Carlson.
