Research Interests and Goals:
My research focuses on the mechanics and morphogenesis of plant development. Plant development is known to be controlled by mechanical factors which, in addition to more extensively studied molecular controls, contribute to the diversity of forms and patterns observed in plants. My personal philosophy is that the best way to explain developmental processes is with an approach that combines experimental work with simple computer models. The need for models is especially acute for problems of morphogenesis since they usually involve changes in space and time. I have therefore built a group that includes biologists, experimental physicists, and applied mathematicians to tackle these problems.
Work in the laboratory is divided in three main areas: cell morphogenesis, meristem growth, and the mechanics of fast movements.
Area 1: Cell Morphogenesis:
Area 2: Meristem Growth:
Area 3: Fast Movements:
