Joshua R. Widhalm studies how plants make and use specialized chemical compounds, particularly naphthoquinones like juglone (a compound produced by black walnut trees that can be toxic to other organisms). His work examines the biosynthesis pathways, transport, and biological roles of these plant chemicals, including their effects on microbes, fungi, and neighboring plants, as well as potential agricultural applications.
