Karen research techniques can be broadly categorized into those that rely on acute cross-sectional experiments and those which rely on data collected from longitudinal studies. Her experimental work combines techniques from clinical neuropsychology and cognitive neuroscience. She was trained in Canada by Prof. Otfried Spreen, arguably Canada's leading Neuropsychologist. She is proficient in functional Magnetic Resonance Imaging, electroencephalography and diffusion tensor imaging techniques. Her intensive involvement with 3 National longitudinal studies (Dunedin Multidisciplinary Health & Development Study; Auckland Birthweight Collaborative study; Growing Up in New Zealand) reflects my interest in life-span development as well as the precursors and determinants of neurodevelopmental disorders and problem behaviour.
The development of cognitive subsystems within the brain, including language and executive functioning. Of particular interest is atypical functioning of these subsystems in the case of dyslexia and Attention Deficit Hyperactivity Disorder.
