My research explores the role of within-species morphological variation in the evolution of arthropods, both extant and fossil. My interest in this area extends to many aspects of paleobiology, including species concepts, phylogenetic analysis, geographic variation, ontogenetic variation, species longevity and biostratigraphy.
