MARK ALPERT is a contributing editor at Scientific American and an internationally bestselling author of science thrillers. His novels for adults -- "Final Theory," "The Omega Theory," "Extinction," and "The Furies" -- are action-packed page-turners that show the frightening potential of near-future technologies. His latest thriller, "The Orion Plan" (to be published in February 2016), is about an alien invasion of New York City.

Mark also writes science thrillers for young adults. His first YA novel, "The Six," is about six dying teenagers who give up their failing bodies to become U.S. Army robots. The sequel, "The Siege," will be published in July 2016.

A lifelong science geek, Mark attended Stuyvesant High School in New York City and then majored in astrophysics at Princeton University. Working with his advisor, the Princeton theorist J. Richard Gott III, Mark wrote his undergraduate thesis on the application of the theory of relativity to Flatland, a model universe with only two spatial dimensions (length and width, but no depth). The resulting paper, "General Relativity in a (2 + 1)-Dimensional Spacetime," was published in the Journal of General Relativity and Gravitation in 1984 and has been cited in more than 100 physics papers since then. (Scientists who are searching for the Theory of Everything are particularly interested in Flatland because the mathematics gets simpler when one spatial dimension is removed from the equations.)

While at Princeton, Mark also studied creative writing with poets Michael Ryan and James Richardson. After graduation he made the fateful (and perhaps foolhardy) decision to pursue poetry rather than physics. So he entered the M.F.A. writing program at Columbia University, where he took courses taught by Stanley Kunitz, Octavio Paz, Derek Walcott, Susan Sontag and Elizabeth Hardwick. Two years later, when he realized that poetry would never pay the bills, Mark became a journalist. He started as a reporter for the Claremont (N.H.) Eagle Times, writing stories about school-board meetings and photographing traffic accidents with his beloved Nikon FG. Then he moved on to the Montgomery (Ala.) Advertiser, where he learned the history of the civil-rights movement by covering George Wallace's last year as governor.

In 1987 he returned to New York as a reporter for Fortune Magazine and over the next five years he wrote about the computer industry and emerging technologies. During the 1990s Mark worked freelance, contributing articles to Popular Mechanics and writing copy for the talking heads on CNN's Moneyline show. Throughout this period he was also writing novels and short stories, but the only piece of fiction he sold was a short story called "My Life with Joanne Christiansen," which was published in Playboy in 1991.

In 1998 Mark joined the board of editors at Scientific American. With his love for science reawakened, he soon came up with another idea for a novel. While working on a special issue about Albert Einstein, he was intrigued by the story of Einstein's long search for a unified field theory that would explain all the forces of Nature. Mark started writing a thriller about high-energy physics, incorporating many of the real ideas and technologies described in the pages of Scientific American: driverless cars, surveillance robots, virtual-reality combat and so on. The result was "Final Theory," which was published by the Touchstone imprint of Simon & Schuster in 2008. Foreign rights to the novel were sold in 23 countries, and the film rights were optioned by Radar Pictures. Touchstone also published the sequel, "The Omega Theory" (2011), which was about religious fanatics who try to trigger Doomsday by altering the quantum algorithm of the universe.

Mark switched from physics to neuroscience in 2013 when his third novel "Extinction" was published by the Thomas Dunne Books imprint of St. Martin's Press. In this thriller, the technology of brain-computer interfaces leads to the emergence of a new species of deadly man-machine hybrids who share a super-intelligent collective consciousness. Foreign translations of "Extinction" were published in Greece and Taiwan. In 2014 Thomas Dunne published Mark's fourth thriller, "The Furies," which told the story of an ancient clan who share a genetic mutation so shocking that they were persecuted as witches for centuries and forced to flee to the wilderness of America four hundred years ago. And in July 2015 Sourcebooks Fire published Mark's first Young Adult novel, "The Six," a thriller about teens trying to retain their humanity while trapped inside weaponized robots.

Mark lives in Manhattan with his wife and two non-robotic teenagers. He's a proud member of Scientific American's softball team, the Big Bangers. More information about his books is available at his website: www.markalpert.com
