I am a forest entomologist. My interests concern the ecology, molecular genetics, molecular systematics, and risk assessment of invasive forest insect pests. I participate in research programs to detect potentially harmful herbivorous pests and to study colonization of native and exotic plants by phyllophagous insects in Asian and European botanical gardens in order to test various hypotheses linked to biological invasions. I am particularly interested in colonization and invasion history of leaf mining insects on woody plants.
