Predictability of flower color genetics in Petunieae

We are studying Petunieae as a model for understanding the predictability of genetic changes associated with flower color evolution at a phylogenetic scale.

Molecular systematics of Solanaceae

A long-standing goal of our research program to elucidate the evolutionary history and biodiversity of the tomato family, Solanaceae. This work incorporates taxonomy, phylogenetics, and biogeography.

Mechanisms of convergent evolution above and below the species level

We are studying how white-flowered morphs evolve within populations and comparing the genetic basis for this intraspecific variation to the changes involved in transitions to white flowers at the species level in the Iochrominae clade (Solanaceae).

Evolution and diversification of red flowers

This project uses a combination of phylogenetics, comparative methods, biochemistry, and anatomy to trace the many origins of red flowers in the Solanaceae and test why this flower color remains so rare.

Pollinators and floral evolution

We study pollination ecology on a macroevolutionary scale to understand how interactions with pollinators shape the evolution of floral differences.

Evolution of the anthocyanin pathway

We are interested in how evolution of the enzymes and transcription factors of the anthocyanin pigment pathway contribute听to the origin of听new flower colors.
