Research Interests

My work has two main goals. The first is to use a comparative approach to help determine the basic mechanisms of auxin mediated patterning. The second is to determine to what extent changes in auxin mediated patterning have had a role in morphological evolution. To these ends I am using phylogenetic analyses of the major auxin transport protein families combined with comparative imaging in both Arabidopsis and the new model grass Brachypodium distachyon to try and relate changes in gene family structure, protein expression domain, and protein function to the differences between monocot and eudicot patterning.
