My research focuses on responses of marine animal behaviour to biological and physical forcing across a range of temporal and spatial scales. Simultaneous quantification of biological and physical properties of the ocean is key to understanding the behavior of marine organisms. I am particularly interested in small-scale variability behaviour, distributions, and predator-prey interactions of fish and zooplankton communities – and how this drives population and ecosystem dynamics. In order to address problems across a range of temporal/spatial scales, I use hydroacoustics in different platforms (vessels, moorings, cabled observatories) combined with net sampling and physical measurements.
