About

My lab is focused on ecology, evolution and conservation of plants. 

  * Is evolution predictable? Does it proceed in repeated directions across the tree of life?

  * What is the molecular basis for convergent evolution?

  * How often do polymorphisms transcend the speciation process?

  * How does pleiotropy constrain the genes involved in adaptation and speciation?

Currently, I am looking for directional trends in flower color evolution, focusing on the most widespread secondary plant pigments, anthocyanins. Anthocyanins are essential for pollinator attraction, yet are constrained by their roles in plant defense, UV protection and other metabolic functions. The six core genes in the linear pathway are conserved across angiosperms allowing for broad comparative studies on the degree of molecular convergence and constraint during plant evolution. We us a combination of spectrophotometry, digital imagery, biochemistry, transcriptomes and whole genomes to discern patterns of flower color ecology & evolution. When coupled with quantitative field experiments to discern the selective agents, my lab hopes to reveal predictable patterns underlying plant diversification. In answering these questions, I strive to develop creative avenues for our diverse undergraduate students to make meaningful contributions to real scientific discoveries.
