Alycia Stigall

 

Alycia, a 2001-2005 Self Fellow, is an assistant professor in the Department of Geological Sciences at Ohio University. Alycia completed her Ph.D. in geology with honors at KU in 2004. She received a B.S. (1999) summa cum laude in geological sciences and biology, with honors in the liberal arts, and with distinction in geology from the Ohio State University and a M.S. (2001) in geology with honors from KU. Alycia's research focuses on analyzing biogeographic and evolutionary patterns of Paleozoic marine invertebrates to determine some of the processes that drive mass extinction. This work represents the first use of GIS to analyze biogeographic ranges of Paleozoic fossils. In particular, she is examining the role of invasive species and geographic range expansion on speciation and extinction rates during the Late Devonian and Late Ordovician biodiversity crises to help predict the long term effects of invasive species in the modern ecosystem. Although her primary research involves fossil brachiopods and bivalves, she also studies the evolutionary patterns of arthropod groups such as crayfish, phyllocarids, and bradoriids. While a Self Fellow, Alycia also traveled to Antarctica to collect fossil specimens of Jurassic freshwater crustaceans to examine the processes of fossilization in high latitude lake systems.
