Ph.D. positions

Simulations and theoretical work in the area of soft matter systems

The Institute for Computational Physics works in the fields of research of simulations and theory of soft matter and biophysical systems, e.g. subjects like nucleation, ionic systems, ferrofluids, hydrogels, as well as colloids, polymers or biomolecules.

At present we have one open position in the group of Christian Holm, see below. However, we can support applications of exceptionally good candidates for funding in other projects. These positions would be in the groups of Maria Fyta, Jens Smiatek, Axel Arnold and Christian Holm.

Common to all applicants should be a strong background in statistical physics and MD or MC simulation strategies, and knowledge of basic soft matter background (polymers, colloids) or knowledge in atomistic modelling (biomolecules, proteins). The simulations will be performed using the software package ESPResSo, GROMACS, or self-written codes. We are also active in the field of algorithm and code development, in particular for electrostatic and hydrodynamic interactions.

There will be ample opportunity to interact with other researchers at Stuttgart, the Max Planck Institute for metals research, the Max-Planck-Institut für Polymerforschung (MPI-P) in Mainz, and the University of Stuttgart.

All positions are initially for one year, renewable upon mutual agreement. Candidates should have the relevant background in a quantitative discipline (see above) and a keen interest in several of the lab's research areas. Applicants should submit:

  • resume (including date of birth, grades, awards, publications),
  • statement of research interests (up to 2 pages),
  • names and email addresses of 2-3 references
  • links to their thesis and/or publications

Positions will remain open until filled. Please send applications via email to, or if you are located in Stuttgart, simply drop by our institute.

PhD Position: Active Matter

We have an immediate opening for a PhD student to study collective behavior in active matter using computer simulations. The system of interest is comprised of shape-anisotropic catalytically driven self-propelled colloids.

Project Description

In this project the PhD candidate will examine the effect of hydrodynamic interactions and fuel depletion in dense systems of anisotropic self-propelled particles using lattice-Boltzmann + Chemical Reaction (LB+CR) simulations. These simulations are to be performed using the in-house simulation package ESPResSo, which the candidate is required to master and extend.

Total mass flux around a catalytically driven self-propelled cylinder.

An integral part of the project is incorporating moving boundary conditions in the LB+CR code that is currently implemented on the GPU level, to enable the study of collective behavior. The candidate will also examine the various propulsion mechanisms that are proposed for catalytically driven colloids, e.g., self-diffusiophoresis and self-electrophoresis. Using the simulations the relevance of these two mechanisms for the experimentally observed self-propulsion is to be clarified.

Funding is secured for a 3 year period, the length of a typical PhD in Germany, but an extension could be granted based on the success of the candidate.

PhD Requirements

We are looking for a candidate who has finished or is close to finishing a Master's in Physics (or associated field) and has a strong background in physics and MC/MD simulations; since the project involves CUDA programming, experience with CUDA would be an asset but is not a requirement, however, the candidate must be knowledgeable on C (or C++/FORTRAN) programming.

Casual inquiries are welcome, if you would like to know more please do not hesitate to contact Dr. J. de Graaf (jgraaf _ at _


Applicants should submit

  • a resume (including date of birth, grades, awards),
  • a brief statement of research interests (max. 2A4 pages, 12 pt. font, incl. figures),
  • a publication list with links to their thesis and publications (if any),
  • contact information for 2 to 3 references (not letters of recommendation),
