Profile/About Me
Our lab studies the ecological and evolutionary processes that generate diversity in flowering plants. We're particularly interested in floral adaptation and plasticity in response to changing abiotic and biotic conditions across both space and time. To this end, we study adaptation across latitudinal and altitudinal gradients, and evaluate phenotypic responses to global change using retrospective herbarium-based approaches. We address questions primarily focused on floral pigmentation and plant mating systems, spanning levels of biological organization from populations to large clades.
