Extinction risk, quantitative biostratigraphy, geographic range, graptolite paleobiology, arthrodire placoderms.
PhD, Graptolite Paleobiology, University at Buffalo – 2018
I am interested in using the fossil record to study patterns of extinction and determining which features of species are most strongly correlated with the risk of extinction. Doing this requires being able to place the timing of events in geologic time precisely and so some of my research involves developing automated biostratigraphic techniques. I am also interested in understanding the paleobiology of arthrodire placoderms, a diverse group of armored fishes which abruptly went extinct at the end of Devonian Period.
