Research interests:
Patterns on Plants:
Plyllotaxis, namely the arrangement of phylla (leaves, florets, etc) has intrigued natural scientists for over four hundred years. Current theories and models of the formation of phyllotactic patterns at the plant apical meristem focus on either transport of the growth hormone auxin or the mechanical buckling of the plant tunica. Each of the mechanisms alone can give rise to an instability that leads to patterned states. However, it is known that the two mechanisms interact with each other instead of acting independently. We (Alan C Newell, Patrick D Shipman and I) develop a model that incorporates the coupling of biochemistry and mechanics.
Front propagation and synchronization:
This new research direction is closely related to the dynamical growth process of plants, whereas it has a broader variety of other applications.
