Emily Underwood grew up on the American River in Coloma, CA, the lucky daughter of die-hard environmentalists. She completed her mouthful of a major, "Representing Science in Language and Culture," at Brown University in May 2007, satisfying her insatiable and sometimes problematic need to study everything at once. After studying the interior world of neuroscience, her attention has returned to the environment upon which all our brains depend. She is now in Santa Barbara, teaching writing at Santa Barbara City College, leading kayaking trips around the Channel Islands, and spreading her fledgling writer's wings.
