Ke Dong




Ke Dong received a B.S. and an M.S. majoring in Entomology from Zhejiang Agricultural and Forestry University and Zhejiang University in China, respectively. She then moved to the US and received her Ph.D. in Entomology from Cornell University in 1993. After a short stay at the University of Kentucky, first as a postdoctoral associate and then research assistant professor, she relocated to Michigan State University (MSU) in 1995. Currently, she is a Professor in the Department of Entomology and in the Genetics and Neuroscience programs at MSU. She has served on the editorial boards of Insect Biochemistry and Molecular Biology and Pesticide Biochemistry and Physiology since 2008.

Over the past two decades, her lab made significant contributions to the understanding of the molecular action of pyrethroid insecticides on sodium channels as well as the molecular mechanism of knockdown resistance (kdr) to pyrethroids. Her current research interests center on the molecular, neuronal and behavioral bases of insect responses (mainly resistance and repellency) to natural and synthetic neuroactive compounds including insecticides.
