Research
I am a marine evolutionary ecologist with research interests in global change ecology, biological oceanography, and sustainable fisheries. I combine theory and modeling with observations and field experiments to understand how ecological systems function. To predict how these complex systems will respond to a rapidly changing world, we need to uncover the underlying mechanisms that drive them. My research focuses on building this understanding and developing stronger tools for ecological prediction.
