Steph is interested in diet and trophic position of extinct marine invertebrates. She is designing projects to investigate the relationship between environmental change, ecological interactions, and trophic position.

Dan is applying stable isotope sclerochronology to reconstruct bivalve physiology. Projects include testing for photosymbiosis in the Jurassic bivalve Lithiotis and conservation paleobiology (growth, longevity, and symbiosis) of Pleistocene, Holocene, and Recent giant clams.


For the 2018-19 academic year, I'm unfortunately not able to admit new students. Sorry! For upcoming years, I am likely only able to consider prospective students who would be strong candidates for external funding (such as the NSF Graduate Research Fellowship) or for our campus-wide fellowships (including one for students who have overcome hardship). I'm happy to help with applications, but note that deadlines for external fellowships are earlier than our internal application deadline. Please contact me ahead of time to discuss research ideas for fellowship proposals!

I'm looking for motivated and passionate students who are interested in developing innovative methods of assessing physiological and ecological traits in extinct taxa and testing their importance during ancient global change events. My admission decisions are strongly influenced by evidence for creativity, resilience, scientific curiosity, and other important characteristics, for example from letters of recommendation, prior research experience, and applicants' personal statements. I strongly support students from diverse backgrounds and I don't consider the prestige of your undergraduate institution when I am recruiting students. I prefer students with a broad coursework experience, but I do not rely heavily on numeric grades. Likewise, our department requires GRE scores but I place almost no weight in them for admission decisions.
