Research Interests

We study how the brain extracts visual information to guide behaviour. From the 2D input that is generated by our photoreceptors, we are somehow able to identify objects, separate them from the background, and determine their motion direction. These fundamental computations happen already in our retina, before the visual information is even sent to the brain. The focus of our laboratory is to understand how visual circuits carry out these computations and how the brain assembles complex percepts from elementary features. 

We use the fruit fly, Drosophila melanogaster, as a model organism utilizing its rich repertoire of visually guided behaviours, powerful genetic tools, and complete electron microscopy connectome datasets. By combining electrophysiology with behavioural analysis and modern Drosophila tools to trace and manipulate neural circuits, we aim to uncover single-neuron computations within the context of brain-wide networks.
