Research Interests

My research focuses on how the brain processes visual information, and how animals use this information to make perceptual decisions. Lab members can gain exposure to many techniques including optogenetics, behavioral tasks, electrophysiology, and computer modelling. We aim to monitor and manipulate targeted components of local and large-scale neural networks to test causal links between neural processing and perception.
