Habitat loss or alteration is one of the main drivers behind global declines in biodiversity. As a result, I am broadly interested in the fundamental connections between a species and its habitat. Recently, I completed work focused on coastal wetlands, using remote sensing and modeling to determine how habitat will respond to predicted changes in water levels. Working in aquatic habitat peaked my interest in fish movement. To this end, I looked at habitat selection by fishes in and among coastal wetlands. Moving forward, I am increasingly curious about the mechanisms behind fish habitat selection and the factors that drive their movement.

My earlier work was focused more at the landscape level and I hope to learn more about fish movement, fish physiology, and telemetry during my time in the Cooke Lab. I am excited to be involved in multiple projects. In early March, I had the opportunity to travel to Denmark to start a study looking at the impact of stress on the out-migration of brown trout. We will hopefully get data for this study in late May or early June.  In Watt’s Creek we have started a study to determine how the fish community will respond following habitat restoration. We will also look at habitat selection and movement of fish species in the creek. Some other projects are in the pipe, so I will update the website once things get finalized.
