Taxonomic Focus: Crabs



The Crandall Lab performs research in population genetics, evolutionary biology, systematics, and bioinformatics. We perform both methodological studies of phylogenetic and population genetic techniques as well as software development of methods for such inferences. We also apply these methods to ask questions concerning the conservation, evolution, and systematics of various organisms focusing on the Crustacea. We also apply such methods to the study of infectious diseases with an emphasis on HIV and Neisseria.
