My name is Doug Pruden, but I publish under my initials, D.M.Pruden. I currently write science fiction, but I spent 35 years as a professional geophysicist in the Canadian petroleum industry. For most of my life I've been plagued with stories banging around inside my head that demanded to be let out into the world. I currently spend my time as an empty nester in Calgary, Alberta, Canada with my long suffering wife of 34 years, Colleen. When I'm not writing science fiction stories, I enjoy playing with my granddaughters and working on improving my golf handicap. I will also do geophysical work when requested.
