Doctoral Student

I have been interested in vision ecology and its relation to behaviour and anatomy since I started studying biology. Already during my second year I studied the contrast vision budgerigars (Melopsittacus undulatus) as a summer project in collaboration with my current supervisors prof. Almut Kelber and dr Olle Lind. My interest in bird vision led me to do my bachelors project for prof. Almut as well, this time studying the retinal ganglion cell topography of Bourke’s parrot (Neopsiphotus bourkii). For my master project I stayed in the Vision Group but shifted my attention towards the tropical nocturnal bee Megalopta genalis and its ability to use the dorsal visual field, where I worked in collaboration with prof. Eric Warrant.

The budgerigar is often used as a model organism for avian vision. My PhD project aims at further investigate their visual abilities using predominately behavioural experiments but also anatomical studies on various bird species. Birds are highly visual animals and we know that their eye morphology, optics and visual abilities often reflect their ecology. One of my main interests is how their visuals systems have adapted to different ecological niches and how this is reflected in anatomy and behaviour.
