The research team under the supervision of RNDr. Šárka Kaňková, Ph.D., focuses mainly on evolutionary psychology, especially in relation to reproduction. One of their main research topics is pregnancy, in various interdisciplinary contexts. The areas of focus include hormonal, immunological, parasitological, behavioral and psychological factors and their interactions. The aim of the team’s research is also to observe the effects of these variables on the development and health of the child. Specific topics that the team focuses on include e.g. the adaptive function of the behavioral immune system and its affective part - disgust, the effect of toxoplasmosis on reproduction, the study of nausea and vomiting in pregnancy and related changes in the composition of gut microbiome.
