Sylvia Fallon, Senior Scientist, Washington, DC

Sylvia Fallon

My interest in the natural world led me to study ecology and evolutionary biology, but after all my schooling I found myself confined to the laboratory studying the arguably inconsequential minutia of blood parasites in birds.  Seeking to use my scientific background for something a little more relevant to the world, I was fortunate to be offered a position with NRDC working on endangered species issues.  Having tried my hand with a biotech company, the National Park Service and even the Environmental Protection Agency, I have a special appreciation for the type of good work done here by my colleagues at NRDC.
