My research interests focus on understanding what the dimensions of human cognition are, how they relate to brain function, how we can best measure them, and how they are affected in clinical populations. This research involves a combination of large scale cognitive testing, functional and structural brain imaging, experimental psychology, psychometrics, computational modelling and machine learning methods. A popular product of this work is the Cognitron, a flexible online platform that my collaborators and I have developed to enable a wide variety of cognitive studies to be conducted at very large population scale, with repeat assessment timepoints and for minimal cost.
