David Denlinger received his undergraduate degree in zoology from the Pennsylvania State University and his Ph.D. in entomology from the University of Illinois. He received a postdoctoral fellowship from the Agricultural University, Wageningen, the Netherlands, an NIH postdoctoral fellowship for work at the International Centre of Insect Physiology and Ecology in Nairobi, Kenya, and then returned to the US as a Research Scientist at Harvard before joining the faculty of Ohio State University, where he advanced from the rank of Assistant Professor to Distinguished University Professor and served as Chair of the Department of Entomology for 11 years. Dr. Denlinger's research focuses on the molecular physiology of insect development, especially the mechanisms used by insects to enter dormancy (diapause) to survive adverse seasons such as winter or tropical dry seasons. His interests range from an ecological understanding of seasonal development, to mechanisms of photoperiodism, to the downstream gene pathways that result in the manifestation of dormancy. His interests in overwintering include probing cold hardiness physiology, experiments that examine the molecules that enable low temperature survival in temperate latitude winters as well as in Antarctica. He has also maintained an active interest in the reproductive physiology of the tsetse fly, vector of African sleeping sickness. He has authored over 300 scientific publications, several books, and has been supported by grants from NIH, NSF and USDA. He is the recipient of numerous awards including election to the National Academy of Sciences, recipient of the Gregor Mendel Medal from the Czech Academy of Sciences; Outstanding Alumnus Award from Penn State; Honorary Fellow of the Royal Entomological Society; Recognition Award in Insect Physiology, Biochemistry and Toxicology, Founders Memorial Award, C.V. Riley Achievement Award, and Fellow of the Entomological Society of America; Antarctic Service Medal; Fellow of the American Association for the Advancement of Science; Honorary Professor of Chinese Academy of Sciences. He served as editor of the Journal of Insect Physiology for 20 years, currently edits Current Opinion in Insect Science, and serves on the editorial boards of seven additional journals.
