Gretchen Ernster Henderson
Facilitator
Interdisciplinary Arts Fellow Gretchen Ernster Henderson (MFA, PhD) is a body of water indebted to many bodies of water: from the Pacific to Atlantic Oceans, Chesapeake to San Francisco Bays, Missouri to Charles Rivers, Icicle to Rock Creeks. She is an intermedia writer, artist, scholar, and educator of ecological and community-engaged practices. Her fifth book, Life in the Tar Seeps: A Spiraling Ecology from a Dying Sea (Trinity University Press 2023), has been melting from Great Salt Lake into the public invitation of Dear Body of Water (in collaboration with the University of Arizona Poetry Center and Kent State University’s Wick Poetry Center): to write love letters to bodies of water to grow a global poem concurrent with communal stewardship around WaterWays. A musician by training, Gretchen is interested in acoustic ecologies and communal practices of listening, meditation, and processes that sound the gaps of cultural and institutional histories, to facilitate participatory spaces for exchanging knowledges and renewing ways of knowing to collectively support our human and more-than-human world.Alisha Bretzman
