Now Recruiting Paleobiology/Macroevolution Graduate Students for 2016

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
Macroevolution, Macroecology,
Early Vertebrates, Ichthyology 
Mass Extinction, Phylogenetics
Biomechanics, Evo-Devo

Listen to a Palaeocast interview about our research on early vertebrate macroevolution and paleobiology

November 13, 2015: Our paper on body size trends ("global shrinkage") after mass extinction is out in Science, with a Perspective by Pete Wagner. Press Coverage in the New York Times, Discovery News, ScienceNow, DailyMail, Penn News, and many more (see Press Page), including video and Science Podcast. 

November 1-4, 2015: Lauren, John, Erynn and Jack presented at the GSA Annual Meeting in Baltimore, MD. Erynn was featured in the Paleontological Society's twitter feed and Jack represented the Society on social media.

October 17, 2015: Our paper on Bandringa has won the Taylor & Francis Award for Best Paper in Journal of Vertebrate Paleontology, second place.

August 28, 2015: Jack Stack has been named a Student Ambassador for the Paleontological Society. He will represent the Society at GSA in Baltimore and on social media. Congratulations, Jack!

August 7, 2015: Lauren received the Stensio Award for top early career researcher at the 13th International Symposium on Early Vertebrates/Lower Vertebrates in Melbourne, Australia!
