Research Summary
We are broadly interested in how global events, environmental change and ecological interactions affect long-term evolution (macroevolution) in early vertebrates (half of vertebrate history) and ray-finned fishes (half of vertebrate diversity).
Research Interests
Paleobiology/Paleontology

News
May 11-13, 2015: Lauren has been invited to speak at the Swedish Royal Academy of Sciences 275th Anniversary Symposium, "Palaeontological and Molecular Approaches to Early Vertebrate Evolution," in Uppsala, Sweden.
February 19-21, 2015: Bryan Juarez has been granted a full travel award to attend the 2015 Emerging Researchers National Conference in STEM, to be held in Washington DC. He will present his research on diversification trends in the earliest lobe-finned fishes.
January 12, 2015: High school volunteer Jack Stack's book and research is featured in the Michigan Morning Sun.
December, 2014: We are now official partners in the NERC-funded project "Tetrapod World: early evolution and diversification." This multidisciplinary, multi-institutional effort involves detailed examination of early Carboniferous sections in Scotland and North England in order to determine vertebrate diversity during "Romer's Gap," the recovery interval following the end-Devonian mass extinction.
