He has more than 35 years experience in Radio Intelligence, now more commonly known as Communications Intelligence. He holds a master’s degree in Strategic Intelligence from the National Intelligence University, where he researched and wrote his master's thesis on the On-The-Roof Gang.
Mr. Zullo has published numerous articles on the On-the-Roof Gang on internal work websites, in the Naval Cryptologic Veterans Association's Cryptolog magazine, and on his social media platforms.
