C. E. Berger is a scientist and author of speculative fiction. She studied film production and philosophy at Boston University and spent a few years working in Hollywood before returning to school to pursue science. She got another bachelor’s degree in physics from the Ohio State University and a PhD in computational physics from UNC Chapel Hill a few years later. Since school is obviously her natural habitat, she now works as a professor at Smith College, where she encourages the next generation of brilliant scientists.
