My research straddles the fields of evolutionary developmental biology, systematics/phylogenetics, and biostratigraphy, and has three major goals:
1. To determine whether and how development constrains morphological diversification, and on what timescale such developmental constraints operate. 2. To improve understanding of the initial radiation of trilobites during the Cambrian, and thus to provide insight into the nature of major evolutionary radiations. 3. To refine the resolution at which biotic and environmental change can be studied within the Cambrian System, a time of exceptional evolutionary significance.
