Lecturer

Paleobiology

My research is centered on understanding the paleobiology of extinct echinoderms (starfish and their allies). My research tends to be phylogenetically oriented and echinoderms lend themselves to a phylogenetic approach because their intricate morphology, coupled with a high degree of morphological disparity, allow for the coding of robust datasets for phylogenetic analysis. At present I am focusing on three fundamental questions:

  1. What is the nature of the Cambrian-Ordovician explosive radiation of echinoderm body plans?
  2. How can phylogeny and development be used to answer paleontological questions?
  3. How is the collection of fossils and consequently our understanding of the fossil record biased by geography, time, and facies?
