Research Interests
I am interested in
the diversity of flower and fruit forms and on the molecular and
morphological
processes that
produce them. I’m particularly interested in how, during angiosperm
evolution, changes in these mechanisms produced novel structures
and architectures. I aim to combine morphological and molecular techniques
to try to uncover these links between molecular and morphological
changes.
Current projects fall into three categories. The first includes
projects that use a comparative phylogenetic approach to studying
plant development and evolution. In one such project, Dr.
Vivian Irish and I are using morphologic, genomic, and molecular techniques
to identify genes involved in the evolution of fleshy fruits in Solanaceae.
A second area of research involves the evolution of the MADS-box
gene family. One project focuses on the functional evolution of the
APETALA1 gene lineage. This gene is crucial for flowering in model
species such as Arabidopsis, but evidence suggests its role has not
been constant during angiosperm evolution. I am investigating the
role of changes in conserved sequence motifs in the functional evolution
of this gene lineage. I am also continuing my work on floral morphology
of Vochysiaceae. This tropical family is known for its beautiful
and unusual flowers, which have a reduced number of organs (one fertile
stamen and often only one petal) and in some cases no symmetry.
