Dr. Johnson is an analytical chemist who has been teaching at USC Lancaster since 2004. Before joining USCL, she worked as a research chemist in the chemical industry for five years. She teaches courses in Introductory, general, forensic, and analytical chemistry at USCL. Her research interests are in applying the tools of analytical chemistry to solve problems in chemistry and biology. Recent work has involved determining the identity and distribution of volatile organic scent compounds emanating from flowers, floral nectar, and nectar inhabiting microorganisms. She also develops novel teaching experiments that engage students and incorporate modern laboratory instrumentation at all levels. Dr. Johnson is involved with community outreach projects to enhance science education and participation amongst K-12 and undergraduate students.
