I am a paleontologist and marine ecologist who studies invertebrate animals, that is, most of the different kinds of animals that have ever lived on Earth. I see my research as comparative:
- describing and explaining the history of life that actually can be observed as patterns in the fossil record, such as the changing forms of skeletons through time, or long-term trends in biodiversity,
- jointly studying processes that can only be inferred from fossils, such as the mechanisms of actual biological interactions, or the evolution of complexity that occurs at the different levels of organism and community, and
- comparing these with patterns and processes that can be seen in the living world, such as the development and life cycles of organisms, and the ecological processes of communities.
