As a botanist and evolutionary biologist, I am fascinated by biological diversity. 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 diversification. I combine bioinformatics, comparative genomics, phylogenetics, and developmental biology to investigate how genetic networks and pathways modify and evolve to produce diverse phenotypes. For my doctoral work, I studied the genomics of floral diversification in the genus Achimenes (Gesneriaceae) and worked to develop this group into a new model system for understanding flower evolution. My postdoctoral research will focus on phylogenomics of the diatom order Thalassiosirales, a model diatom lineage that spans the marine-freshwater salinity gradient and exhibits substantial genome size variation.
