Mats J. Olsson's research group

Human olfaction

The overall aims of Mats J. Olssons groups research is to understand how we perceive different odorants, and how these characteristics feed into later cognitive stages of processing, such as memory and metacognition. Moreover, Mats J. Olssons group investigate how exposure to body odor affect our mood, behavior, and physiology.

Research projects

  • How are odorous substances integrated perceptually?
  • What can body odor communicate?
