Allan Larson's research combines natural history and molecular biology to evaluate patterns and processes of evolution at multiple levels of biological complexity. Molecular phylogenetic approaches are used to study historical biogeography, genomic evolution, developmental and morphological evolution, and the genetic structures of natural populations. Salamanders and lizards constitute his main study systems. Procedures used include amplification and sequencing of mitochodrial and nuclear DNA. He offers courses and seminars at the graduate level in molecular evolution, macroevolution, and the history of evolutionary theory. His research and teaching feature interactions with Drs. Garland Allen, Jonathan Losos, Alan Templeton, and their associates.
