Norman A. Johnson

Norman A. Johnson is an Adjunct Assistant Professor in the Biology department at the University of Massachusetts Amherst. His research focuses on evolutionary biology, particularly the genetics and evolution of postmating reproductive isolation barriers in insects. He uses Drosophila and Tribolium (flour beetles) as model systems to study hybrid sterility, sperm precedence, and quantitative genetics of hybrid traits.

Education: Ph.D. in 1992 from the University of Rochester. His work bridges empirical and theoretical approaches despite currently being non-experimental, informed by prior experimental studies. He is affiliated with the Organismic and Evolutionary Biology program, with an office at 203 French Hall.

Research interests emphasize biodiversity formation through speciation processes, specifically postzygotic isolation mechanisms. No awards or grants are explicitly listed, though his work contributes to foundational evolutionary biology research.
