Pat Reilly has been conducting bioelectromagnetics research for over 50 years, with over 160 published works, including 4 major text books. He first studied radar propagation at the Johns Hopkins University Applied Physics Laboratory beginning in 1965 when he was in graduate school. In the mid 70’s, he started to investigate electrical influence on environment and people, and was a principle advisor to the Maryland State Department of Natural Resources providing biologically-based assessment of the electromagnetic effects of transmission lines across the electromagnetic spectrum. Since the early 80’s, Pat Reilly has concentrated his focus on human sensitivity to electrical stimulation by contact currents and by induction from exposure to electric and magnetic fields. More recently he has been providing consulting work on the safety and effectiveness of electrical stun devices and electrical effects on astronauts during extravehicular activities.
