- I am broadly interested in social relationships and social evolution, trying to understand the “hows and whys” of health and fitness benefits of strong affiliative relationships and social integration. I am particularly interested in the links between sociality, health and physiology and the mechanisms by which social interactions can impact health, e.g. exposure and susceptibility to pathogens. For my Ph.D., I am investigating those links in semi free-ranging Barbary macaques at Affenberg Salem, Southwest Germany, working on the effect of social network position, social relationships and physiology on gastrointestinal parasite infection.
Working on parasite infections, I also developed a strong interest in host-parasite interactions and disease ecology as well as immunology – and, by extension, health monitoring using non-invasive markers, as for instance neopterin, and a deep scientific curiosity for animal personalities and the physiology of aging, particularly in combination with relationships and health.
