Sara Cathey

Biological Sciences

Sara is studying the response of stream insect metacommunities in a river network to landscape disturbance as part of Dr. Bryan Brown’s lab.

She earned a Bachelor’s of Science in Marine and Freshwater Biology from The University of Texas at Austin. As a student, she worked at the university’s Biodiversity Collections, cataloging specimens and processing samples for the Ichthyology collection. After graduation, she worked as a research assistant testing the keystone community concept. She then moved to Maine to work as a research assistant on a microplastic study, examining the global distribution of microplastic in the world’s surface waters.


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