California

I have been studying white sharks (Carcharodon carcharias) in California for over 15 years. My research focus spans population modeling, physiology, movements, and behavior. My initial research looked at abundance and population dynamics in white sharks off of central California. More recently my work has been to develop cutting-edge technologies to study the movements, behavior and physiology of white sharks.

My work in California has been the focus of popular media including the Discovery Channel shows 'Great White Highway' and ‘Blue Serengeti’.

Biologging tags, like this orange one here, can provide insights into shark physiology, movements and behaviors.

South Africa

In South Africa I began deploying the first biologging camera tags on white sharks near Dyer Island in 2013. My continued work here is focuses on understanding the kinematics of these amazing predators. By attaching non-invasive fin-mounted biologging tags, which record tri-axial movement data as well as video and environmental data, we can reconstruct the hidden lives of these amazing predators.

This camera tag on a 3.4m white shark showed us new hunting strategies in white sharks in Gansbaai, South Africa.

 

Oregon

At OSU, while continuing projects in California and South Africa, I am studying the movements and responses of apex predators to changing ocean conditions and their expanding roles in coastal ecosystems. Specifically I will continue work on white, salmon, mako and thresher sharks.
