# Bill S. Hansson

Bill S. Hansson (born 1959) is a Swedish neuroethologist. From June 2014 until June 2020, he was vice president of the Max Planck Society.

## 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, until he was appointed Director and Scientific Member at the Max Planck Institute for Chemical Ecology in Jena, Germany in 2006. He is head of the Department of Evolutionary Neuroethology. In 2010 the Friedrich Schiller University in Jena appointed him Honorary Professor.
Hansson's research focuses on neuroethological aspects of insect-insect and insect-plant interactions. He is mainly studying insect olfaction, 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? He also compares these systems to other land-living arthropods, as the giant robber crab on Christmas Island.
