I am co-leader of the Adaptive Behaviour Research Group, where I focus on computational modeling but interact with, and support, experimental work in human psychophysics, neuroscience and robotics. One of the hallmarks of my research is building models at different levels of description: from individual conductance-based neurons, through microcircuits of reduced neuron models and large scale spiking networks, to population-based (rate-coded) models with robotic embodiment, and abstract mathematical descriptions. Specific areas of interest include:
This has been my main focus for over a decade. I am seeking to answer question such as: how do we ‘decide what to do next’, given the plethora of behavioural demands at any moment, and how do we make perceptual decisions when confronted with noisy, ambiguous stimuli. This work is predicated on the hypothesis that the basal ganglia (BG) play a key role in these processes and my lab has developed several models at many scales of description including: population level models of BG and its loops with cortex – a compartmental model of individual neurons in striatum , a spiking model of the BG , and models of the striatal microcircuit , . The models have also been subject to Bayesian analysis , .
Closely linked with action selection, this work seeks to answer the question: how do we learn new skills and actions and how can we use the resulting knowledge in goal-directed behaviour? The initial focus here was a critique of the role of phasic dopamine in learning . The main ideas have been tested in a large scale model  and a simulated autonomous robot .
This work grew out of work to test our models of action selection in complete, biologically grounded sensorimotor loops – in this case visual perception and gaze control –. I am also interested in understanding the minimal substrate required for aspects of cognitive vision as demonstrated in the honeybee - a topic within the recently awarded Green Brain project.
What principled approaches should we use in building computational models of the brain? How should we integrate models at different scales of description? These are questions addressed in , .
Neuroinformatics and software tool development
Science has often made step changes when the appropriate tools have been invented. I am interested in developing high throughput parameter fitting techniques for conductance-based models , , ) and model description languages .
