Jim has a B.Sc. in Engineering Physics from Queen’s University, Kingston, Ontario, Canada and a Ph.D. in experimental Nuclear Physics from McMaster University, Hamilton, Ontario Canada (under Dr M.W. (Martin) Johns, then Head of the Physics Department).

After a year on the faculty of the Physics Department at the University of Windsor, Windsor, Ontario, Canada immediately following completion of his Ph.D. studies, he took a job with one of Canada’s major defence electronics system integration companies where he worked for 37 years. The first 20 years he spent developing passive and active sonar systems for shipborne, airborne and fixed applications that are in use with the Canadian, Portuguese, Belgian, Swedish and US Navies. The subsequent 17 years he spent developing integrated, secure, digital voice and data ground mobile tactical communications systems that are used by the Canadian and British armies. During his career, Jim held positions in software engineering, system engineering, program management and line management, including VP Engineering and Chief Technology Officer responsible for research and development. He served for several years on the company’s Executive Committee.

Jim grew up attending church regularly in a mainline Protestant denomination, reaching high school graduation without ever hearing the message of salvation and left the church and the faith when he took Geology 101 in first year engineering. Although he and his family resumed church attendance (in another mainline Protestant denomination) because he and his wife thought it would be good for their two young girls, it wasn’t until almost his 40th birthday that he heard the message of salvation when attending an evangelical church in response to the invitation of a friend and neighbour and subsequently accepted Christ.

However, Jim was initially what might be called a bi-polar Christian, believing in the salvation provided by Jesus but also believing in the evolutionary account of origins, the big bang, etc. It wasn’t until he attended a weekend seminar conducted by young-earth creation scientists where he saw that science and scripture were completely coherent. Since that time, largely as a result of information available from CMI, he has become increasingly amazed at how the truth of scripture is confirmed in every area of science and become increasingly concerned about how evolution is used as a means to avoid confronting the claims of Jesus.

Since retiring, he has felt called to use his scientific background to show others that the Bible is believable from first verse to last. Before joining CMI, he gave presentations on the creation-evolution issue to the College and Career groups at two local churches and facilitated a multi-week discussion group on the topic at the church he attends.

Dr Mason’s hobbies include skiing (downhill and cross-country), gardening/landscaping, renovations, and spending time with his two grandchildren. He and his wife Rosemary have three children and reside just outside Lakefield, Ontario near their two granddaughters.
