John Schenk

Our lab is interested in understanding the evolutionary processes that have generated such a remarkable amount of morphological forms and diversity in plants. We apply a macroevolutionary approach that takes advantage of traditional anatomical and morphological methods, phylogenetic comparative methods, ecology, and genomics to better understand how forms have evolved through time.
