Bronson joined the faculty in 1982 as a fungal geneticist. Her primary interest is on the genetics of Cohilobolus heterostrophus and its overall pathogenicity to maize. She teaches the course in Genetics and Epidemiology. She was on faculty improvement leave at Stanford University in 1986 and later in Japan. She rapidly became an authority in her field. A perfectionist in her work, quality rather than quantity is her trademark.
