Hihi chicks

My research focus is on adaptation and the ecological, genetic and evolutionary consequences of conservation interventions and management of species under anthropogenic threat. To do this I apply genetic, quantitative genetic and genomic techniques to wild and captive-bred populations of threatened birds. I collaborate closely with government bodies, NGOs/charities and community groups, which enables me to successfully apply my research.
More recently, I have been developing a program of research on emergent threats to wildlife looking specifically at the impact of air pollution from vehicle emissions on wildlife genetic health using the invasive Eastern grey squirrel as a model system.
