Research Interests

The major topics of my research include image analysis, graph theory and statistics. I work on automated, computational frameworks to analyze microscopy images by quantifying certain processes in plants. These frameworks include the automated extraction and analysis of cytoskeletal components, such as actin filaments, by representing them as networks. The extracted networks can then be used for quantitative analysis of actin in time series, between different conditions or for the testing against random networks.

Furthermore, I work on the development of a framework to describe the complex shape of pavement cells in the upper epidermis of plant leaves. Due to their shape complexity, pavement cell shapes are hard to describe in a quantitative manner. We developed a network-based framework to quantify, compare and classify cell shapes by analyzing global and local shape features.
