Something scenicI am a Senior Research Scientist in the School of Biology at Georgia Tech. My current research focuses on questions related to the evolution of multicellularity.
My PhD from the University of Arizona focused on evolutionary transitions in individuality (ETIs) generally, and specifically in the transition from unicellular to differentiated multicellular life in the volvocine green algae. I was co-advised by Rick Michod and Régis Ferrière. My PhD research incorporated theoretical, empirical, and comparative approaches to explore the selective pressures that may have driven this transition.
