I am interested in the the molecular mechanisms that lead to developmental phase transitions in plants. In my PhD I looked into signalling mechanisms stimulating cell proliferation to initiate secondary growth in Arabidopsis roots, a process that can be used to model secondary growth in trees. More recently I have become more interested in advanced imaging tools and using these not only to characterise phenotypes but also to quantify dynamically the underlying cellular processes. Here at UZH I will use such tools to quantify chromatin structural changes that are involved in the transition from dark- to light-growth.
