David L. Denlinger is one of the world's leading researchers on insect diapause. He is a Distinguished University Professor, and Professor Emeritus of Entomology, at the Ohio State University, USA. He is a member of the National Academy of Sciences, a Fellow of the Entomological Society of America and an Honorary Fellow of the Royal Entomological Society. Professor Denlinger's current laboratory research focuses primarily on molecular mechanisms involved in insect overwintering. His interests range from the use of clock genes to perceive environmental signals through the endocrine and molecular events that result in expression of the diapause phenotype. He has received numerous awards for his research including the Gregor Mendel Medal from the Czech Academy of Sciences (2006), the Antarctic Service Medal (2006), and the ICIPE Achievement Award (2020).
