Research focus

In my group, we study development of roots and communication with their physical and biological environments at the single-cell level. We use genomics and state-of-the-art fluorescence-based microscopy in combination with near-native physiological set-ups that involve precise control of nutrient and light availability. Our platform is flipped 90 degrees to allow long-term root imaging and is equipped with LED light illumination and fluidic media exchange systems.
