Dr. Johnson has been associated with Samford University since 1967 -- first as an undergraduate, then as a Masters student, then as a visiting professor during two missionary sabbaticals, and most recently (since Fall 2008) as a full-time faculty member. Prior to this final appointment, he spent nearly twenty years as a teaching missionary at Seinan Gakuin University in Fukuoka, Japan.

Dr. Johnson's expertise is genetics and molecular biology, so at Samford he handles Genetics, Experimental Genetics, and Cell & Molecular Biology. In his Experimental Genetics class likes his students to get "hands on" experience and so they perform a variety of exercises including karyotyping, fruit fly crosses, gene cloning, and DNA sequencing.

Dr. Johnson's research interests are in several fields of genetics and molecular biology, using DNA to investigate problems from honeybee parasites to molecular identification of local single-celled organisms to the diet of the invasive kudzu bug.

Dr. Johnson and his wife, Robin, have two grown children and two grandchildren. They enjoy entertaining students at their annual Halloween and St. Patrick's Day parties.
