Norton’s research focuses on the ecology and evolution of pest organisms and their hosts.
Norton, a member of the graduate degree program in ecology at CSU, studies interactions in biological control systems – arthropods, crop plants, weeds, pathogens and their natural enemies – as well as indirect effects and interaction modification.
Current research projects include the examination of interactions between plant resource availability and the efficacy of weed biological control agents, biological control of and the development of appropriate management strategies for tamarisk (Tamarix spp.), toadflaxes (Linaria vulgaris & L. dalmatica), and pollinator-mediated competition between invasive weeds and native plants.
Norton received his B.A. in biology from the University of California, Santa Cruz, in 1985. He earned his Ph.D. in entomology from the University of California, Berkeley, in 1995.
