I am a systems engineer and technologist by profession, with a longstanding interest in steamships and sailing vessels, the study of naval architecture, and the practice of celestial and coastal navigation. I have been involved with the study of Titanic for many years, and I am the principal author of: 'Report Into the Loss of the SS Titanic – A Centennial Reappraisal' (The History Press, 2011), principal author of: 'The Sting of the Hawke: Collision in the Solent' (printed by CreateSpace, an Amazon.com company; January 2015) that was co-authored with Mark Chirnside, author of: 'Strangers on the Horizon: Titanic and Californian – A Forensic Approach' (printed by Amazon Kindle Direct Publishing, 2019), and co-author of 'Titanic: Solving the Mysteries' (Blurb Books, 2019) with J. Kent Layton, et.al. I also have written numerous research articles for the Titanic Historical Society’s: The Titanic Commutator, the British Titanic Society’s: Atlantic Daily Bulletin, the Irish Titanic Historical Society’s: White Star Journal, and the Titanic International Society’s: Voyage. I have also published a number of online articles at: Encyclopedia Titanica, Great Lakes Titanic Society, Titanic Research and Modeling Association, Mark Chirnside’s Reception Room, and on my own Titanicology website. In addition to the above, I have conducted an in-depth analysis and report into the 1956 collision between Stockholm and Andrea Doria that was presented at the Maine Maritime Academy in 2008, and is currently available on my Titanicology website. I also hold a private pilot’s certificate for single-engine land aircraft, and was a yachtsman’s mate and coastal navigator on a Catalina 25 in the 1980s, spending many weekends cruising the waters off Staten Island, Sandy Hook and Lower New York Bay.
