Stefan Helmreich received his B.A. from University of California, Los Angeles (Anthropology, 1989) and his M.A. and Ph.D. from Stanford University (Anthropology, 1995). He has worked as a Postdoctoral Associate in Science and Technology Studies at Cornell University, an External Faculty Fellow at the Center for the Critical Analysis of Contemporary Culture at Rutgers University, and as Assistant Professor of Science and Society at New York University. The National Science Foundation and the Wenner-Gren Foundation have funded his research. Helmreich's research examines the works and lives of contemporary biologists puzzling through the conceptual boundaries of “life” as a category of analysis. He has written extensively on Artificial Life, most notably in Silicon Second Nature: Culturing Artificial Life in a Digital World (University of California Press, 1998), which in 2001 won the Diana Forsythe Book Prize from the American Anthropological Association. His latest book, Alien Ocean: Anthropological Voyages in Microbial Seas (University of California Press, 2009), is a study of marine biologists working in realms usually out of sight and reach: the microscopic world, the deep sea, and oceans outside national sovereignty. Working alongside scientists in labs and at sea, Helmreich charts how revolutions in genomics, bioinformatics, and remote sensing press marine biologists to see the sea as animated by its smallest inhabitants: marine microbes, which are being rendered meaningful as pointers to the origin of life, barometers of climate change, raw materials for biotechnology, and analogues for extraterrestrial life.

Alien Ocean immerses readers in worlds being newly explored by marine biologists, worlds usually out of sight and reach: the deep sea, the microscopic realm, and oceans beyond national boundaries. Working alongside scientists at sea and in labs in Monterey Bay, Hawai'i, the Woods Hole Oceanographic Institution, and the Sargasso Sea and at undersea volcanoes in the eastern Pacific, Stefan Helmreich charts how revolutions in genomics, bioinformatics, and remote sensing have ed marine biologists to see the sea as animated by its smallest inhabitants: marine microbes. Thriving in astonishingly extreme conditions, such microbes have become key figures in scientific and public debates about the origin of life, climate change, biotechnology, and even the possibility of life on other worlds.
