Bill S. Hansson (born 1959) is a Swedish neuroethologist. From June 2014 until June 2020, he was vice president of the Max Planck Society.The team around Martin Stratmann MPG Info, June 5, 2014
Scientific career Hansson studied biology at Lund University where he received a Bachelor of Science degree in biology in 1982. In 1988 he defended his PhD thesis in Ecology. From 1989 to 1990 he worked as postdoc at the University of Arizona and returned 1990 to a junior professorship in Lund. In 1992 he became Associate Professor and from 2000 until 2001 he was a Professor for Chemical Ecology at Lund University (2000). From 2001 he was Professor and Head of the Chemical Ecology department at the Swedish University of Agricultural Sciences (SLU) in Alnarp, Sweden. He also served as vice dean for the Faculty of Landscape Planning, Horticulture, and Agriculture from 2003, until he was appointed Director and Scientific Member at the Max Planck Institute for Chemical Ecology in Jena, Germany in 2006. He was head of the Department of Evolutionary Neuroethology.MPI for Chemical Ecology Website until his retirement in 2025. Between 2014 and 2020 Hansson also served as Vice President of the Max Planck Society. He is now emeritus Director at the Jena institute. In 2025 he took up the position as Distinguished Professor at the Agricultural Genomics Institute in Shenzhen, Chinese Academy of Agricultural Sciences. He also holds positions as Honorary Professor at the University of Jena, at the Nanjing Agricultural University and at Hainan University, and as emeritus Professor at SLU.
Hansson's research focuses on neuroethological aspects of insect-insect and insect-plant interactions. He is mainly studying insect olfaction,Olfactory Research Is a Precision Business MaxPlanckResearch Magazine 3 /2009 where his central questions are: How is semiochemical information (odors) detected by the antenna and processed in the insect brain, how did these detection and processing systems evolve, and how does olfaction guide insect behavior?Molecular messages from the antennae MPG News, April 15, 2011Fruit Fly Nose Says Steer Clear Of Deadly Food National Public Radio USA, Dec. 6, 2012 He also compares these systems to other land-living arthropods, as the giant robber crab on Christmas Island.A Nose for Survival Science Now, Jan. 26, 2005
