Personal profile

Biography

I was born and brought up in Switzerland where I studied biology at the University of Zürich with a focus on Ethology (animal behaviour). At that time I was particularly interested in cognitive and social processes in primates and horses. In 1994 I came to Australia to do my PhD in the Developmental Neurobiology group at the ANU. My project explored the relationship between the structure and function of the tammar wallaby's visual system. The unusual photoreceptor topography I observed in these animals sparked my interest in visual ecology. After the completion of my PhD I joined the Visual Sciences group (ANU) where I began work on the ecology of visual information processing in fiddler crabs. I joined UWA in 2012 to work on the visual control of behaviour in fiddler crabs. The relationship between sensory processing and animal behaviour is the main focus of my research group. Much of our work is highly comparative and involves a range of different animals. We work on ants and crabs to crocodiles, lizards, fish, sharks and dunnarts.

Roles and responsibilities

Roles
- Honours coordinator School of Animal Biology
- Academic editor PLOS ONE
- UWA CMCA's Scientific Advisory Committee member
- Member Editorial Advisory Board Journal of Experimental Biology

Research Techniques
- Analysis of animal behaviour: Field and laboratory work (macaques, wallabies, possums, dunnarts, flies, bees, lizards, ants, crabs)
- Spectrographic imaging and measurements
- Quantitative video film analysis, Multiple camera calibration / alignment
- Immunocytochemistry (retinal wholemounts, tammar wallaby)
- Microspectrophotometry (MSP) (tammar wallaby, spotted quoll)
- Electrophysiology: Electroretinogram recordings (ERG), Visual Evoked Potentials (VEP) and Patch clamp recordings (tammar wallaby), Intracellular recordings (crabs)
- Extensive experience in multivariate statistical analysis and experimental design including: Multiple regression, Generalised linear regression, Generalised Linear Mixed Models, Residual Maximum Likelihood Analysis, Permutation analysis

Major software design
- Digi: A sophisticated C/Matlab based analogue/digital video analysis system. The x-y-position analysis of video sequences includes automated frame by frame tracking of individual objects and their orientation. Includes detailed labelling of behaviours and extensive search capabilities.
- Digilite: A free, simplified, fully Matlab based version of DIGI developed together with Robert Parker.
- C-program (Linux) for the control of an operant conditioning apparatus for visual discrimination experiments.
