Area(s) of Research

My areas of research include the conservation and population genetics of marine teleosts and elasmobranchs. The bulk of my research involves the assessment of both the historical and contemporary genetic connectivity of populations of marine species across their distribution. I am also particularly interested in evaluating the impacts of overfishing on the genetic diversity of heavily exploited species.
