Research Interests

Computations in Neural Circuits

We are interested in how the external world is represented by the brain. To address this question we focus on how sensory information is transformed by neural circuits in the early sensory pathways. What computations do these circuits perform and how they are implemented by the neural hardware? 

We use a range of cutting edge techniques to explore how neural circuits operate, including: electrophysiology, 2-photon imaging, computational modelling and optogenetics. See my lab page for more details
