From 2007 to 2011, Greg blogged for the UFO and paranormal site Ufomystic. His 2017 book "It Defies Language" anthologized entries from that blog along with new material. In 2017, he contributed an essay entitled “The Co-Creation Hypothesis” for the anthology "UFOs: Reframing the Debate." In 2019, he co-authored "A Is For Adamski," an encyclopedic overview of the UFO contact movement. His long-running podcast can be heard at radiomisterioso.com. His latest project is a tarot deck based on the history of UFO research entitled the Ufology Tarot.
He has appeared in many documentaries, such as Fields of Fear (about the cattle mutilation phenomenon) and Mirage Men (based on his book Project Beta), and in the Travel Channel series Mysteries at the National Parks and the History Channel series Unidentified. He also served as guest and subject consultant for the TNN series The Conspiracy Zone with Kevin Nealon. For nearly two decades, he has lectured extensively at conferences, conventions and colleges and universities.

Evidence of his historical research is his acclaimed book, "Triangular UFOs: An Estimate of the Situation." Here, he has provided a comprehensive analysis of triangular UFOs. He has collected, collated, and analyzed hundreds of reports. In the process, he has created a detailed profile of these objects and written a rich narrative of their history. David’s perpetual work in this field was recently recognized by him being awarded the 2022 UFO Congress Lifetime Achievement Award.
In November of 2020, he became the curator of the world’s single-largest historical collection of UFO case files in the world. These files include the historic NICAP and CUFOS case files in addition to Dr. Hynek’s original Project Blue Book files. He was offered the rare invitation of serving as a full Board Member with Dr. J. Allen Hynek’s Center for UFO Studies (or CUFOS). David willing accepted this invitation and now serves in the role as their official Archivist.
David has one of the largest historical UFO archives of books, journals, magazines, newspapers, microfilms, audio recordings, and case files from around the world that covers the last 75+ years. Due to this and additional UFO collections being donated to him, in November of 2022, David and his colleagues launched the National UFO Historical Records Center in the Albuquerque, NM area. This non-profit organization will serve as the largest U.S. UFO/UAP historical archive where David serves as the Executive Director. Work is currently underway to secure a building and donations to make this vision a reality.
