In the News
A number of our research projects have been picked up by various blogs and news organizations. It's always fun to get the chance to talk to science journalists and through them, to the public. Here are some links to coverage of our work, which might help explain some of the topics we're studying.
Coverage of the FIRE (Feedback in Realistic Environments) simulations
FIRE simulations are also featured in the films "Star Men" (Director Alison E. Rose, 2015) and the symphonic film "Deep Field" (Composer/director Eric Whitacre, 2019). These have played at a variety of film festivals and special screenings, limited theatrical releases, and planetaria throughout the country.
Recently our simulations have also been incorporated into "Stellarscape," an immersive multimedia performance synthesizing music, science, visual art, and technology.
