I work in environmental education and watershed protection, with a background in chemistry (and to a lesser extent, physics/electronics). I believe in connecting people with ideas, clarifying concepts, and staying true to the purpose of science - to discover, to understand, and to inform public policy. My public involvement in investigating and protecting the environment starts with a community that shares these beliefs, and depends on open access to scientific methods and tools to do the work, and share the results.

Chesapeake Conservation Corps Alumni, 2016 UMBC, 2014, with a Chemistry B.S. and Environmental Science minor.
