Welcome

Welcome to the Wojciechowski lab in the School of Life Sciences at Arizona State University in Tempe.  We study the phylogenetics and the evolution of flowering plants, with a particular emphasis on legumes (family Fabaceae or Leguminosae) and cacti (family Cactaceae).  Our primary areas of interest include the phylogenetic systematics of papilionoid legumes, the genomics of legumes and cacti, and plant community ecology and floristics of western North America.  Our goal is to understand patterns and processes at the macroevolutionary level (e.g., ecology and biogeography, rates of molecular evolution and taxonomic diversification) by integrating empirical data with comparative and phylogenetic methods to infer relationships and evolutionary histories.
