The Hanken Lab studies the evolution of morphology, developmental biology, and systematics. Most work focuses on amphibians but otherwise addresses a wide range of topics, taxa, and methodologies. The latter range from laboratory-based molecular analyses to extensive field surveys. 

Current subjects include the evolution of craniofacial patterning invertebrates; the developmental basis of life-history evolution; systematics, taxonomy and evolution of African frogs and neotropical and Asian salamanders; and amphibian declines and conservation. Active field programs are maintained in Mexico, China and Africa. We also are very active in the Encyclopedia of Life, and especially EOL's Learning + Education group, which is based at MCZ.
