Short presentation
I study the diversity and variability of animal mating patterns and parental care patterns, in terms of evolutionary behavioural ecology. In particular I enjoy to study the amazing reproductive ecology of pipefishes with multiple matings, predominant female mating competition and male pregnancy. I am also dedicated to teaching of evolution, organismal diversity, the scientific method, marine and behavioural ecology as well as gender perspectives in biology.
