She often teaches Analytical chemistry courses, including CHEM 30333, Quantitative Chemical Analysis and CHEM 60541, Genomics and Proteomics. In both of these classes, Hummon discusses the state-of-the-art research in chemical measurement science while also describing fundamental theory. Hummon also teaches CHEM 10101, Foundations of Chemistry to non-majors. In this course, Hummon is committed to teaching her students the enormous impact that chemistry has had on human civilization. In each class, she and her students discuss one molecule that changed human history and the implications for mankind, with penicillin, synthetic rubber, and nicotine as examples. The course combines lectures with extensive chemical demonstrations. For her teaching in these three classes, Hummon received the Joyce Award for Excellence in Undergraduate Teaching in 2016.
