Regal grew up in Newark's Ironbound neighborhood, in a Catholic family. He developed an early interest for science and the mysterious, which he attributes to television series such as Jonny Quest and later In Search of....^[6]

Discouraged from pursuing higher education by a high school guidance counselor ("kids like you don't go to college"), Regal joined the armed forces, serving as a tank commander.^[7]

Going to college after his military career, he graduated with a B.A. in History from Kean University in 1995, then a M.A. in American History and Literature at Drew University (1996) and a Doctorate in Modern History and Literature from Drew University (2001). He teaches at Kean University, where he holds the title of Associate Professor for the History of Science, Technology and Medicine.^[8]

Regal has long been interested on how theories of human evolution have been received by the public and by religious authorities. His first two books, Henry Fairfield Osborn: Race and the Search for the Origins of Man and Human Evolution: A Guide to the Debates, explore that theme.^[9]

In 2005, he realized that Grover Krantz's estate donated his notes and papers to the Smithsonian Institution after his death in 2002, where they remained unread. Within the collection, Regal found a significant amount of source documents on the founding of American cryptozoology. Those documents were the starting point for The Secret History of the Jersey Devil.^[10]

As of 2021, he was working on a book about various alternative theories of Europeans coming to North America before Christopher Columbus and how those theories relate to the sociopolitical context of the period when they appear.^[6][8][10]

He is a member of the history journal Endeavour.^[11]
