Andrew Alverson is an evolutionary biologist whose research combines phylogenetic, experimental, and evolutionary genomic approaches to identify the ecological and genomic factors driving the diversification of diatoms. He received his B.S. in Biology from Grand Valley State University in 1997, an M.S. from Iowa State University in 2000, and a Ph.D. from The University of Texas at Austin in 2006. For his Ph.D. research, Andrew studied the patterns and consequences of marine–freshwater transitions by diatoms, a diverse lineage of microalgae that produce some 20% of the earth’s oxygen. From there he went on to Indiana University where he worked on the evolution of mitochondrial genome size in flowering plants with funding from a NIH NRSA Postdoctoral Fellowship. Andrew became an Assistant Professor in the Department of Biological Sciences at the University of Arkansas in 2011.
