Research Interests

My laboratory has the goal of understanding the mechanisms of plant development, using both experimental and computational methods to test hypotheses. We concentrate on the shoot apical meristem and its derivative structures (primarily flowers), because this meristem is responsible for the development of the entire above-ground part of the mature plant, and utilizes a number of different pattern-forming processes that are as yet poorly understood. Our experimental organism is predominantly Arabidopsis thaliana, because of the ease with which genetic and molecular biological studies can be done using that model system. We also use other plant species in the laboratory when they offer an experimental advantage. Our method of study is what we have termed Computational Morphodynamics – the combination of real-time live imaging to capture the dynamics of plant development, couching our hypotheses as mathematical models (so as to be absolutely explicit about assumptions and parameters), and then testing them computationally and experimentally. We concentrate on three processes in plant development - the development of flowers, the growth of shoots, and the de novo generation of shoot meristems during regeneration.
