Pierrick is a philosopher of biology at Macquarie University, in Australia, with a background in evolutionary biology and ecology. Pierrick works mainly on conceptual issues related to evolutionary theory, the concept of biological individuality, and major transitions in evolution. He also has interests in the philosophy of causation and cognitive science.
Pierrick has recently published a short book at Cambridge University Press in which he explores the status of units and levels of selection in evolutionary theory. He proposes a suite of criteria to distinguish genuine from arbitrary or conventional units and levels of selection.
