Jason's research focuses on evolutionary investigations of phytophagous (plant-feeding) insects in the hemipteran suborder Auchenorrhyncha; he is specifically interested in planthoppers (superfamily Fulgoroidea), spittlebugs and froghoppers (Cercopoidea), and treehoppers (Membracidae). He uses DNA nucleotide sequencing and comparative morphology to reconstruct the evolutionary history of these diverse and charismatic insects; using those results, Jason evaluates alternative theories of the evolution of insect anatomy, behavior, and biogeographical distribution. Many of the insect species included in his research projects are of worldwide economic and agricultural importance (including pests of rice, corn, and sugarcane), and so results of these projects may have broader implications for studies on the control of such insects.
