Research

My research is in the field of systems biology, more specifically pattern formation in plant development. I use mathematical and computational methods to analyze biological systems based on experimental data. My goal is to further understand the mechanisms that lead to the patterns that are observed in various plant structures, such as leaves and roots. The available data are used to construct mathematical models. The predictions of the following simulations are tested against real data and possibly the model improved. By cooperating with biologists, the mathematical modeling is tightly linked to up-to-date research in experimental biology.

My research at CBBP focuses on the plant root, and it involves mathematical models for different aspects of auxin transport and the development of root hairs. I am part of the group of Prof. Dr. Henrik Jönsson [link]. This work is in collaboration with Prof. Dr. Markus Grebe at Umeå University [link] and embedded in the ShapeSystems project that is funded by the Knut and Alice Wallenberg Foundation.

Previously, I have worked as a scientific assistant and PhD student in the group of Prof. Dr. Jens Timmer at the Center for Biological Systems Analysis (ZBSA) of the University of Freiburg in Germany [link]. My research was supervised by Dr. Christian Fleck [link], it has been on the formation of trichomes (plant hairs) on leaves of the model plant Arabidopsis thaliana. This work was in collaboration with the group of Prof. Dr. Martin Hülskamp at the Universität zu Köln in Germany [link]. For the image analysis we also collaborated with the group of Junior-Prof. Dr.-Ing. Olaf Ronneberger at the Universität Freiburg [link].



Academic Education & Employment

I have studied Biomathematics at the Universität Greifswald in Germany with longer study visits in New Zealand (2003) and Canada (2004 and 2005). In 2006, I obtained my Diplom degree and started working as a scientific assitant and PhD student at the Universität Freiburg in Germany, mainly in the Center for Biosystems Analysis (ZBSA). I obtained my PhD in 2012 and moved to Sweden as a postdoc at Lunds Universitet.
