Research Interests

Study of fossil mollusks and what the fossil record shows about the origins and early evolution of the classes of mollusks. Studies mostly concerned with pelecypods (bivalves), chitons, and the extinct class Rostroconchia from Cambrian and Ordovician rocks. In addition to evolution and phylogeny, my studies deal with paleoecology and biostratigraphy.
