Research Interests: Research in my lab focuses on the evolution, paleoecology, and preservation of animals during their initial radiation of the Ediacaran and Cambrian Periods (ca. 635- 488 million years ago). Known popularly as the “Cambrian explosion,” this radiation is one of the most critical events in the history of life on Earth, with complex animals evolving for the first time, radiating throughout the world’s oceans, and diversifying into most of the major animal groups that we still see today. An increasingly complex web of ecological interactions was a fundamental part of this radiation. We find the first evidence for macropredation, extensive skeletonization, deep burrowing in the seafloor, and macroscopic sense organ development during this event.
