Research InterestsResearch Interests
Dr. Hopkins’s research focuses on the study of morphological evolution in the fossil record. She is interested in the quantification and analysis of complex morphology; analysis of within-lineage tempo and mode of evolution; the influence of covariation and ontogenetic variation on the long-term evolution of lineages; the interaction between morphological change and environmental change; and the importance of scale and hierarchy in understanding long-term patterns of evolutionary change and the processes underlying them.
Dr. Hopkins’s taxonomic interest lies with arthropods. Most of her research focuses on the paleobiology and early evolutionary history of trilobites, but she has also studied variation in extant fiddler crabs. Her research makes use of a variety of quantitative methods, including geometric morphometrics, phylogenetic comparative methods, and time series analysis. Many projects are specimen based and rely on the extensive use of museum and new field collections. Other projects have made use of community databases, such as the Paleobiology Database. She is active in field work, particularly the United States and Scandinavia.
