Research interests

Broadly speaking, I'm interested in the origins and evolution of biological complexity. Living systems are organized in ways that are fundamentally distinct than non-living ones. But identifying the specific differences is not trivial, and we need to incorporate concepts and knowledge from many disciplines, including philosophy, computation, mathematics, and others.
