Scientific interest:
My main research interest lies in investigating cellular growth dynamics in plant cells. I mostly work on Arabidopsis thaliana pollen tubes as models, as they are single cells and elongate uni-directionally. Growing plant cells require continuous monitoring of their cell wall integrity and coordination of the latter with their internal growth machinery. In pollen tubes, the cell wall integrity pathway is governed by two redundant receptor-like kinases of the CrRLK1L- subfamily, named ANXUR1/2. In my project, I focus on two putative downstream members of the ANXUR-dependent pathway, the protein phosphatases ATUNIS1/2, and investigate their function in pollen tube growth.

Outside of the lab, I like bouldering, Rugby, running and music, as well as brewing and tasting beer =)
