KTH Royal Institute of Technology in Stockholm has grown to become one of Europe's leading technical and engineering universities, as well as a key centre of intellectual talent and innovation. We are Sweden's largest technical research and learning institution and home to students, researchers and faculty from around the world. Our research and education covers a wide area including natural sciences and all branches of engineering, as well as in architecture, industrial management, urban planning, history and philosophy.

INTERFACE is a newly established multidisciplinary research environment financed by the Swedish Research Council (VR) after a highly competitive selection process. The environment merges the competence of three existing centers; Linné FLOW Centre , Swedish e-Science Research Centre (SeRC) and Wallenberg Wood Science Centre (WWSC). The aim is to educate a new generation of PhD students with a more pronounced multidisciplinary background and build the basis for future excellence research in Sweden.

Job description

The INTERFACE research group led by associate professors Berk Hess and Shervin Bagheri aims to create the next generation tools to model flow transport phenomena occurring at fluid/solid interfaces. The tools will enable us to predict properties of flows over complex slippery surfaces, and design robust multi-functional surface coatings to control fluid flows.

You will combine physical modeling of surfaces using statistical thermodynamics with computational modelling of fluid flows across multiple length scales. The models will be used to create a fundamental understanding of how a fluid flowing over a surface is altered by the underlying mesoscopic texture (e.g roughness, patterns) and the microscopic molecular details of the surface. The tools and the associated understanding from this project, will in turn be used by other research projects to design robust and efficient surfaces that can interact with flowing fluids in a favorable way, for example to reduce fluid friction, increase heat transfer or fluid mixing.

More specifically, we are looking for a physicist, ideally with a background in thermodynamics, to investigate the stability of phase boundaries under shear flows. You will be working in a collaborative environment that encompasses the range from atomistic (molecular dynamics) to computational fluid dynamics (CFD) at the macro scale. Your role is to develop models for stability of phase boundary configurations obtained from CFD. If needed, molecular dynamics can be used to test the validity of these models, as well as for obtaining parameters.

You will work in close connection with other projects in INTERFACE involving novel biomaterials and nano-patterned surfaces for heat transfer. You will also interact with projects involving experiments on textured, porous and superhydrophobic surface at KTH.


We are looking for you who:
  • Have an Engineering or Master's Degree in physics with specialization in statistical thermodynamics, computational physics or fluids.
  • Have a sound foundation in numerical analysis, physics and programming.
  • Have good academic results in particularly relevant topics for this project.
  • Are able to communicate well verbally and in writing, in English.  

It will be considered an advantage if you have additional knowledge in the relevant subject acquired through, for example, your thesis or course work at other universities.

As a person, you are problem solving and self-motivated. You act with certainty despite limited knowledge and experience, and dare to try new ideas and go beyond your comfort zone. You take great responsibility in your work and we find it important that you find creative solutions while being critical in your analysis. You will be part of a larger research group and you are expected to build contacts both within and outside your group so it is important that you are good at communicating and building relationships. We will place great emphasis on personal qualities.
