Jim Segala is an American physicist and engineer who studies the physical and medical effects people report after close encounters with anomalous phenomena. He was part of the main cast of the first season of History's The Secret of Skinwalker Ranch, which premiered in March 2020, and he now leads MUPAS, a citizen-science project that places sensors in the homes of people who report UAP experiences.
His speaker biographies describe him as holding a doctorate in physics and advanced degrees in engineering, with more than thirty years designing experimental systems and more than nine years as a researcher at the Institute for Advanced Studies at Austin, working on quantum entanglement, quantum optics, vacuum polarization and neurobiology. Matt Ford of The Good Trouble Show has reported that Segala studied under Hal Puthoff, who sent him to Skinwalker Ranch after people there were injured. Segala has said he worked on the property early alongside medical doctors examining visitors' symptoms, and he was billed on the series as the ranch's chief scientist. He told Ford he left after the first season because the show would not let him prove what he believed was happening.
According to Segala, the monitoring equipment he began designing around 2015 became the Modular Unidentified Phenomena Alert System. Its devices record electromagnetic energy, gamma radiation, motion disturbances and biometric data around the clock, while participants keep journals without seeing the readings. Segala says the first phase ran for three years with 36 participants and reached 4.5 sigma statistical significance, that the network has grown past 400 homes, and that his experiencer group shows axonal microbleeds resembling published Havana Syndrome findings. He has said methodology papers are being prepared with two universities.
In 2026 Segala became a regular voice on these questions. He discussed his work at Skinwalker and Blind Frog ranches with George Noory in an interview Coast to Coast AM featured in May, and in September he told The Good Trouble Show that Utah's Uinta Basin is "chock full of the exact same type of thing." On October 4 he and Paul Hynek answered questions from the Anomalous Coalition subreddits in a livestream hosted by Leslie Kean. His significance lies in taking the injury reports that drew scientists to Skinwalker Ranch and turning them into a long-running home sensor study of experiencers.

Last year I attended Carbondalien Fest in Carbondale PA -- a small festival celebrating our area's UFO history and the infamous 1974 sighting. If you haven't heard of it, we can get into that. The fest was a little cheesy (which is to be expected) but honestly a lot of fun between the local theatre involvement, vendors, speakers, and just how everyone got into it. I own a video production company here in NEPA and have always wanted to produce some UFO-related content. Been sorta looking for t...

Im lucky I got out with just hyperintense T2 brain lesions, a "third heartbeat" and a heart that keeps "misfiring" according to the echocardiogram after a decade of experimentation. But my daughter whom I so foolishly included is permanently disabled for however long of a life she has left. @dwpasulka is correct to warn people that we dont know what we're dealing with here. Id hopes that @JimSegala_Mupa...

I’m currently conducting an important field investigation in California that could corroborate some of David Grusch’s claims from last week. More on that later. [Quoted] My good friend and Reddit guru Andrea O from the Anomalous Coalition is holding an event today, starting in half an hour. Jim Segala is doing fantastic work, and Paul Hynek is a legend.

[Retweeted] 🚨 TODAY, 1 PM ET / 10 AM PT Physicist Dr. Jim Segala and Paul Hynek (son of J. Allen Hynek) take questions from Reddit's six largest UAP communities, live. Hosted by Leslie Kean. Measuring what happens in experiencers' homes. Verifiable evidence from contact. Citizen science that doesn't wait on the government. Streamed live here on X in my profile @TheAnomalousC ▶️ https://t.co/z1sI2ZRCBM Also on Twitch.
