Janina is generally very interested in social evolution of animals and their behavioural ecology. The topics she already had contact with, like social immunity, influence of pathogens and symbionts on their hosts, factors that shape different kinds of behaviour (maternal care, sibling cooperation/conflict, food sharing, pathogen defence) aroused her interest for a career in science and she therefore looked for a PhD in this field. With research on the evolution of sociality in ambrosia beetles she can now dig deeper into the coevolution of sociality and fungiculture.
