He is ​currently ​Chief Scientist at the Institute of Noetic Sciences (IONS), in Petaluma, California, USA,​ having joined the IONS research staff in 2001. ​Since 2016, ​Radin ​has also been Associated Distinguished Professor of Integral and Transpersonal Psychology at the California Institute of Integral Studies​,​ and ​is ​four-time President of the Parapsychological Association, an elected affiliate of the American Association for the Advancement of Science (AAAS). He ​has served as co-editor-in-chief of the Elsevier journal ​​Explore: The Journal of Science and Healing​ since 2009​.

Radin earned an undergraduate degree in electrical engineering, ​​magna cum laude and with honors in physics, from the University of Massachusetts Amherst, as well as both a Master's degree in electrical engineering and a doctorate in Educational Psychology from the University of Illinois at Urbana-Champaign. After graduation, Radin worked at Bell Labs, and then ​held appointments at Princeton University, GTE Laboratories, University of Edinburgh, University of Nevada, SRI International, and Interval Research Corporation.

Radin has published over 250 articles and scientific ​papers​, well as three books directed to a popular audience: ​​The Conscious Universe (1997), ​​Entangled Minds​ (2006)​, and ​​Supernormal​ (2013)​.

Radin has conducted parapsychological research in several areas, drawing a conclusion that some psychic phenomena exist. ​He has appeared in dozens of documentary films, television and radio shows, and was featured on the BBC's ​​Horizon TV series explaining an experiment he designed that recorded people's emotional response ​before viewing a randomized series of pictures. He believes the results to be evidence of retrocausation, a controversial conclusion supported by leading edge concepts on the nature of time​,​ and presented at two AAAS sympos​ia on the physics ​of ​time. The effect has since been independently ​and successfully ​replicate​d​ some 40 times by researchers around the world.
