William I. Ausich studies fossil echinoderms, especially crinoids (sea lilies), examining their evolutionary history, classification, functional shapes, and the environments in which they lived from the Ordovician through Permian periods (roughly 480 to 250 million years ago). His work combines detailed descriptions of new fossil species with broader questions about how ancient marine communities were structured and how these organisms adapted over deep time.
Publication output has been fairly steady over the last decade, peaking around 2019 with 13 papers and settling to a somewhat lower but consistent pace of about 6-8 papers per year in recent years.
