Neural circuit basis of sexually dimorphic and learned behaviours in Drosophila
Group Leader page
We have a variety of interests investigating the circuit logic of innate behaviours, especially sexually dimorphic behaviours dependent on pheromones. We are also interested in how learned behaviours interact with and suppress innate behavioural responses.
On the technical side we also have major efforts in tool development to enable mapping of neural circuits including processing multi-terabyte light microscopy datasets. We are also leading a large collaborative effort using whole brain connectomics with EM data that is opening up many opportunities to map neural circuits at synaptic resolution (see http://www.zoo.cam.ac.uk/departments/connectomics).
Please get in touch to discuss specific project ideas (in these area or indeed any area of our group’s work) that match your own scientific interests. Projects are likely to involve a combination of the techniques in the lab including molecular genetic manipulations, quantitative behaviour, optogenetics and electrophysiology/multiphoton imaging, connectomics and computational neuroanatomy.
Since we have developed (and will continue to develop) a variety of molecular genetic and software tools and imaging and behavioural hardware, we would strongly encourage applications from students with an aptitude for software or hardware development or some background in physical / quantitative sciences as well as a serious interest in brain and behaviour.
