Sara joined the Department of Biological Sciences in 2017 as a student in Dr. Bryan Brown’s lab. Sara focuses her research effort on patterns of biodiversity and community assembly and stability in freshwater ecosystems. Her current work investigates the role of dispersal in community response to disturbance and how this response varies across a stream network.
Throughout her research career, Sara has centered her work on drivers of global change. This has included the habitat preference of a disease causing algae, Gambierdiscus; examining invasive species policy; testing the effects of community removal on network diversity and stability; and the distribution and sources of microplastic pollution.

Freshwater systems are facing multiple stressors, all of which could affect stream biodiversity and ecosystem functioning. As a Fellow in the Interfaces of Global Change program, Sara hopes to gain a more thorough understanding of how global change will continue to threaten freshwater systems, so that she can help find solutions to mitigating the effects.
