Postdoctoral Research Fellow, Hopkins Marine Station


I am a postdoc in the Goldbogen lab at Hopkins Marine Station studying biomechanics and energetics in filter feeding fish. Our research uses a range of approaches, including respirometry, swim tunnels and hi-speed video to examine energy use and kinematics in sardines and anchovies. These forage fish, which are vital important components of the Monterey Bay ecosystem, switch between different feeding modes with different energetic requirements depending on the food source available. Of particular interest, they ram filter feed, that is swim with their mouths open filtering particulate food and smaller organisms from the water, a highly energetically costly swimming mode in the dense aquatic environment where minimizing hydrodynamic drag is usually a priority. Previous to my position at Hopkins, I studied metabolic rates and body-size mediated responses of sea urchins to warming and ocean acidification at the University of Sydney, as a postdoc in the lab of Prof. Maria Byrne. My PhD completed at Queen's University Belfast studies metabolic scaling relationships in chitons and echinoderms. My ongoing research interests include metabolic allometry, body size, and responses of marine species to climate change.
