One of the central questions in developmental biology is how organs form in the correct positions in order to create a functional mature organism. Plant leaves offer an easily observable example of organ positioning, with species-specific motifs for...

What dynamic processes are responsible for the development of complex body plans? I will approach this from a chemical perspective, looking at what types of dynamics can form spatial concentration patterns. I will discuss two areas in which we are...

The growth regulator auxin plays a central role in development across plants. Auxin spatial patterning is critical in the phyllotactic arrangement of leaves along a stem, the shapes of the leaves themselves, and venation within leaves. These patterns...
