As a botanist and evolutionary biologist, I am fascinated by the enormous diversity of plant forms and flower morphology. Understanding diversification at the macro- and microevolutionary scales has long been a central goal of evolutionary biology. My research aims to understand the patterns and processes of diversfication. I combine bioinformatics, comparative genomics, phylogenetics, and developmental biology to investigate how underlying genetic networks and pathways have evolved to produce diverse phenotypes. I am particularly interested in the evolution of floral form in the genus Achimenes (Gesneriaceae), a colorful and diverse genus native to Mexico and Central America.
