PhD position is proposed in the framework of the International Research Training Group (IRTG) “Soft Matter Science”, a joint PhD program of the Universities of Strasbourg/France and Freiburg/Germany. The primary workplace will be at the Charles Sadron Institute in Strasbourg (~70%). The secondary workplace will be at the Botanical Garden of the University of Freiburg (~30%). Expected starting date is November 1, 2014.
This International Research Training Group brings together chemists, physicists and engineers from all over the world aiming to develop concepts for the design of innovative materials with a high level of functionality.

Project description
In many applications, the adhesive and frictional properties of polymer surfaces represent key features controlling performance and durability. For example, it is often crucial to fine-tune the adhesive properties and a possible solution to this problem is micro-texturation of the polymer surfaces. The present project intends to integrate these considerations in a larger study which addresses not only adhesive but also frictional properties of micro-patterned polymer surfaces directly inspired by plant surfaces. Through these considerations, the aim of this project is an enhanced understanding of the natural system and a transfer into the soft matter general case: it consists in identifying and understanding how topography in terms of shape and scale influences adhesive and frictional properties.

The approach consists of three parts:
1. Fabrication and microscopic characterisation of bio-inspired microstructured polymer surfaces (Freiburg)
2. Friction and adhesion experiments on the fabricated surfaces (Strasbourg)
3. Numerical modelling for validation of the experimental interpretations (Strasbourg/Freiburg)

We offer
- Comprehensive, interdisciplinary research in soft matter science
- Supportive mentoring by at least two advisors
- Exchange with PhD students of the participating laboratories in Germany, France and Switzerland

Training through
- Introductory and advanced courses in the research field of the IRTG
- Specialised workshops and training camps
- Wide spectrum of further qualification measures

Requirements
We are looking for highly qualified and motivated graduates holding a master's degree (or equivalent) in mechanics, engineering, material science, biology, physics or related areas with excellent grades. Particular interest in experimental work and Finite Element Modelling skills will be highly appreciated. Applicants should be strongly interested to expand their horizon beyond the specific field of their major and should have excellent proficiency in English as all teaching will be in English. We particularly encourage women to apply.

For the format and the documents required for the application please refer to our website www.softmattergraduate.uni-freiburg.de. Applications must be sent by e-mail tosoftmattergraduate@uni-freiburg.de (deadline: October 15, 2014).
