Staff profile

Phil Stephens graduated in Zoology from Bristol, took an MSc. in Conservation Biology at the Durrell Institute of Conservation and Ecology and gained his PhD in population ecology from the University of East Anglia (2002).  His principal interests are in how evolved traits shape the fates of individuals and how those fates sum to determine the dynamics of populations.  These interests inform research on evolution, behaviour and conservation more broadly.
