Francine H Mejia

I am an aquatic ecologist at the U.S. Geological Survey. I am interested in pairing biological and physical sciences to understand the structure and function of streams and rivers.

My research focuses on aquatic productivity, water quality, and habitat restoration. I am stationed in Usk, Washington and partner with the Kalispel Tribe of Indians to help them monitor and restore culturally important aquatic habitats. These projects range from reach scale monitoring to global analyses.
