Associate Professor Sheri Johnson

Associate Professor Sheri Johnson is a reproductive ecologist, based at the Centre for Reproduction & Genomics and the Department of Anatomy at the University of Otago.

Born and raised in Canada, Sheri graduated with a BSc (Hons) at Dalhousie University, before moving on to the University of Maine to complete her PhD in 2007. Sheri was a postdoctoral fellow at the University of Florida before taking up her current position at Otago.

Sheri has broad interests in ecology, evolution and behaviour. Sheri uses an integrative approach (molecular, field ecology, reproductive biology and behavioural analysis) to understand the factors that affect reproductive success and mate choice in fish and marine invertebrates.
