Dan's an award-winning foreign correspondent specializing in "adventure science." Much like George Plimpton spending a season with the Detroit Lions to write about football, Dan's gone into the jungle with biologists in search of rare wildlife—and into the tunnel of the world's largest machine with physicists looking for the Higgs Boson. His articles have appeared in Scientific American, International Wildlife, Audubon, Science, Natural History, Cosmos, and on the BBC. He's a TEDx speaker, and held a Fulbright to Australia. He worked for CERN in Geneva, Switzerland, as editor of an on-line weekly magazine, where his office was 100 yards away from the LHC's "injection point." If the machine made a black hole, he'd have been first to know.
