2007- 2012 PhD thesis on the territorial behaviour and its relation to testosterone in the black redstart. Supervised by Wolfgang Goymann (MPI for Ornithology, Germany)
2002- 2007 Ludwig-Maximilians-Universität (LMU), Munich, Germany. Diploma thesis on behavioural and hormonal effects of social isolation and neophobia in a flocking bird species, the starling (MPI for Ornithology and LMU).

Research interest

The main aim of my work is to understand basic relationships between behaviour, hormones and reproductive success and how these relationships vary on a seasonal basis and in different environments. I am using birds as model systems to study the role of the steroid hormones testosterone and corticosterone as mediators of reproductive behaviours (e.g. territorial behaviour, song and parental care). My study sites lie in tropical East Africa and in temperate Europe. In particular, I currently study how life history variation has shaped variation in behaviour and physiology in stonechats and how habitat fragmentation and degradation affects behaviour, physiology and fitness of an East African cloud forest bird species.
