Main research focus:

We study the interactions between plants and herbivore insects. Five major research themes include (1) the physiology of plant antiherbivore defenses, (2) the ecology of plant-insect interactions, (3) the evolution of plant-insect interactions, (4) the influence of abiotic factors on plant-insect interactions, (5) agricultural/ecological application of plant-insect interactions. We welcome students and early-career scientists interested in insect herbivores and plants to join our lab.
