Paul Lewis teaches American literature and writing workshops at Boston College, and he brings a career-long interest in dark humor to the writing of A Is for Asteroids, Z Is for Zombies. A student of gothic and gallows humor, Lewis has written extensively on these strains in U.S. popular culture, most notably in his book Cracking Up: American Humor in a Time of Conflict (UChicago Press, 2006). The neologist who coined the words "Frankenfood" and "lackspertise" in a letter he wrote to the New York Times, Lewis has published op-ed, feature, and humor pieces in leading newspapers.
