Since he began his career as a science journalist in 1980, Yulsman has written for a variety of major publications, including the New York Times, Washington Post, Denver Post, Discover, Audubon, Earth and Astronomy. His journalistic work currently focuses on the earth and environmental sciences. Prior to joining the journalism school's faculty in 1996, Yulsman was editor-in-chief of Earth magazine. Until it's closure in 1998, Earth was the only consumer magazine dedicated to the science of our planet.
As a science journalist, Yulsman has written one book: Origins: the Quest for Our Cosmic Roots, published by the Institute of Physics in 2003. Other recent works include "Grass is Greener", a feature about the coming biofuels revolution, for Audubon magazine; "Meltdown" a story about glacial retreat in Glacier National Park, for Audubon; and "The Day the Sea Stood Still", an article for the Washington Post about the Late Paleocene Thermal Maximum, one of the most dramatic episodes of global climate change in Earth history.
Yulsman is now moving into multimedia journalism. He recently co-produced a video side bar to accompany his biofuels article on Audubon magazine's website, and more multimedia packages are on the way.
