Witness filmmaker Christi Cooper grew up in Boulder, Colorado, where she was fortunate to be surrounded by people who helped her develop a strong connection to nature and the outdoors. Her passion for science resulted in a M.S. in microbiology from Colorado State University and a Ph.D. in neuroscience from the University of Regensburg, Germany. After spending years in research, she followed her dream of documentary filmmaking by pursuing an M.F.A. in the Science and Nature Filmmaking program at Montana State University. She is the co-director of iMatters Trust: Calling for Climate Recovery (Mountainfilm 2012) documentary series that features young climate change activists from across the U.S. Cooper continued her focus on youth activism in her latest film, Youth v Gov (Mountainfilm 2021).
