I am an evolutionary biologist and a former Senior Research Scientist at Georgia Tech. My recent research focuses on questions related to the evolution of multicellularity. My curriculum vitae is here. I am currently serving as a Program Director in the Evolutionary Processes Cluster in the National Science Foundation’s Division of Environmental Biology. Anything I post here or on social media reflects only my personal views and does not necessarily represent the views of my employer or the United States.

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.

You can also find me on Google Scholar and ResearchGate. My ORCID is 0000-0002-9578-0972. On Bluesky, I am @matthewherron.bsky.social.
