The focus of my work is the evolutionary ecology of developmental plasticity in plants. Developmental plasticity can be defined as the ability to execute morphogenetical decisions based on perceived information. Developmental plasticity plays a major role in the adaptation of both animals and plants to heterogeneous environments and is thought to be of particular importance in plants because of their limited motility. In my research I am trying to bridge the gulf between physiological, ecological and evolutionary approaches. Though the emphasis of my research is on adaptations and behaviors of individual plants, I am also studying the consequences of developmental plasticity at higher organizational levels. The premise is that an interdisciplinary and multi-hierarchical approach can advance our understanding of plant adaptation to changing environments.
