Cognitive psychologist / neuroscientist with a passion for computational modelling and behavioral research. I’m interested in how we make sense of the world using visual perception as a model. How do we perceive things that have varying features, such as color or orientation, how do we decide which features belong to which object, and what do we do after we make such decisions?
