Tom Campbell began researching altered states of consciousness with Bob Monroe at Monroe Laboratories in the early 1970s where he and a few others were instrumental in getting Monroe's laboratory for the study of consciousness up and running. These early drug-free consciousness pioneers helped design experiments, developed the technology for creating specific altered states, and were the main subjects of study (guinea pigs) all at the same time. Campbell has been experimenting with, and exploring the subjective and objective mind ever since.
For the past thirty years, he has been focused on scientifically exploring the properties, boundaries, and abilities of consciousness. During that same time period, he has excelled as a working scientist, a professional physicist dedicated to pushing back the frontiers of cutting edge technology, large-system simulation, technology development and integration, and complex system vulnerability and risk analysis. Presently, and for the past 20 years, he has been at the heart of developing US missile defense systems.
