Research and Teaching Interests

  • The systematics of minnows and their relatives (Cypriniformes) using phylogenomics

  • The systematics of the South American catfish subfamilies Hypostominae and Ancistrinae (Loricariidae), and their evolutionary ecology
  • Formation of the modern Guyana ichthyofauna
  • Phylogenetics of the North American cavefishes (Amblyopsidae), and revision of the Southern Cavefish (Typhlichthys subterraneus)
