Jeffrey Kluger joined TIME Magazine as a contributor in 1996, and was named a Senior Writer in 1998.

He is most recently the author of Splendid Solution: Jonas Salk and the Conquest of Polio. He is also the co-author, along with astronaut Jim Lovell, of Lost Moon: The Perilous Voyage of Apollo 13 (retitled Apollo 13 in paperback), which served as the basis of the "Apollo 13" movie released in 1995. He later wrote Journey Beyond Selene, a book about the unmanned exploration of the solar system. At TIME, he has written a number of cover stories, including reports on the connection between sex and health, the Mars Pathfinder landing, the loss of the shuttle Columbia and the collision aboard the Mir space station.

In 2002, Kluger along with two other colleagues won First Place in the Overseas Press Club of America's Whitman Bassow Award for the best reporting in any medium on international environmental issues for their "Global Warming" cover package (April 9, 2001).

Prior to joining TIME, Kluger was a staff writer for Discover magazine, where he wrote the Light Elements humor column, and was also a writer and editor for New York Times Business World Magazine, Family Circle and Science Digest.

Kluger is also a licensed attorney, and intermittently taught science journalism at New York University.
