Welcome to our lab group! We study the interplay between evolutionary and ecological processes in shaping biodiversity. Our current research focuses on freshwater fish and lake food webs in New Zealand including Rēkohu/ Chatham Island. Our interests include intraspecific niche variation, life history evolution, phylogenetic comparative methods, and the effects of salinisation and altered connectivity on populations and food webs.

We are located at the University of Otago (Ōtākou Whakaihu Waka), in Ōtepoti Dunedin on the South Island of Aotearoa New Zealand. Our home is the Department of Zoology (Te Tari Mātai Kararehe), and our field sites include lakes, streams and wetlands throughout Rēkohu and the South Island.
