Research interests:

Study organisms: free-living birds

Approaches: field observation and experiment, lab experiment, phylogenetic comparison


(1) life history–physiology nexus

- life-history traits: growth, reproduction, survival and lifespan, as well as costly phenotypic traits that are linked to fitness (e.g. brain size)

- physiology: oxidative stress, immunity and insulin-like growth factor 1, as well as parasite infestation (e.g. coccidiosis)

(2) physiology of animal personalities

(3) plumage, moult, wing morphology and flight

- plumage: feather quality, feather structure and colouration

- wing morphology: wing loading, aspect ratio
