His work is acknowledged by several prizes, documented by the choice and election in international scientific organizations, and through the prestigious Humboldt foundation.
Understanding the cellular mechanisms that direct organ growth in response to internal and environmental cues is a major challenge for plant biology. Although numerous studies have provided insight into the regulatory networks that direct organ growth and shape, surprisingly little is known about how cells and organs develop in three-dimensional space. To understand the cellular mechanisms that direct organ growth of plants in response to internal and environmental cues, large-scale methods have been developed for a quantitative analysis of cells and organs in situ. An advanced fully robotized imaging pipeline allows us to accurately visualize how single cells reprogram and differentiate into tissues and organs. An intrinsic root coordinate system enables a direct quantitative comparison between root tips at single cell resolution. Even subtle changes in cell division patterns within the root apical meristem can be monitored.
