From 1966 to 1970, he was on the research staff of the Institute of Parapsychology (formerly the Foundation for Research on the Nature of Man) in Durham, North Carolina, where he worked on such books as Parapsychology Today and Test Your ESP.

He served as chairman of the philosophy department from 1981 to 1996 and has also served as the director of the National Endowment for the Humanities' "Egyptology Today" program. He was appointed Senior Research Fellow at LIU Post in 2004. In addition to his career at Long Island University, Brier has taught ancient Egyptian at The New School and Egyptology at Webb Institute for many years. Brier has conducted research in mummification practices worldwide. He has investigated well-known mummies such as Tutankhamen, Ramses the Great, Vladimir Lenin, Eva Perón (more commonly known as Evita), and the Medici family. In 1994, Brier and a colleague, Ronald Wade, director of the State Anatomy Board of Maryland, claimed to be the first people in 2,000 years to mummify a human cadaver using ancient Egyptian techniques. This research earned Brier the affectionate nickname "Mr. Mummy" and was also the subject of the National Geographic television special of the same name, which made him a household name. He is also the host of several television programmes for the TLC Network including The Great Egyptians, Pyramids, Mummies and Tombs, and Mummy Detective. His research has been featured in Archaeology Magazine, The New York Times, CNN, 60 Minutes and 20/20. In 1999, Brier gave a series of 48 specially-prepared lectures entitled "The History of Ancient Egypt" for The Teaching Company. He later did another series of 12 lectures for them, focusing on "Great Pharaohs of Ancient Egypt". Brier is a recipient of Long Island University's David Newton award for Teaching Excellence. He leads tours to Egypt for Far Horizons Archaeological and Cultural trips.
