Paul Gilster – Director at large

gilsterPaul Gilster is a full-time writer who focuses on space technology and its implications. He is one of the founders of the Tau Zero Foundation, an organization that grew out of work begun in NASA’s Breakthrough Propulsion Physics program and now supports research into advanced propulsion for interstellar missions. Gilster is the author of seven books, including Digital Literacy (John Wiley & Sons, 1997) and Centauri Dreams: Imagining and Planning for Interstellar Flight (Copernicus, 2004), a study of the technologies that may one day make it possible to send a probe to the nearest star. He tracks ongoing developments in interstellar research from propulsion to exoplanet studies on his Centauri Dreams Web site (www.centauri-dreams.org). In past years, Gilster has contributed to numerous technology and business magazines, and has published essays, feature stories, reviews and fiction in a wide range of publications both in and out of the space and technology arena. He is a graduate of Grinnell College (IA)​ who performed graduate work in medieval literature at UNC-Chapel Hill before going into commercial aviation​ (flight instructor specializing in instrument and commercial training)​. He turned to full-time technology writing in 1985.


Douglas Loss – Director at large

lossDoug is originally from central Pennsylvania; he has worked in the IT field, principally in network administration and security, for the past 30 years. He organized and ran an international internet organization called SEUL/edu, which fostered and promoted the development and use of Open Source software in schools around the world. He handed operation of that organization off when its focus became less IT and more education (this change in focus was intended and encouraged from the beginning), as he wasn’t an educator.

From 1977 until the early 2000s he attended and eventually organized The Asimov Seminar, a yearly, four-day-long retreat at a conference center in upstate New York. Isaac Asimov, the noted science fiction author, was the star of the Seminar and its main draw until his death in 1992. Each year the Seminar would explore a different topic, always with some (sometimes vague) connection to science fiction. The topics were always approached interactively, with the Seminar attendees assuming roles that would allow them to examine the questions associated with that year’s topic on a personal basis. Doug currently lives in Maryville, TN with his wife Ruby.
