Dr Kartik Iyer is a postdoctoral researcher at QIMR Berghofer with a biomedical engineering and computational neuroscience background, and nearly a decade of experience in the fields of child development, neurotrauma, and brain mapping. He combines highly multidisciplinary skillsets including biomedical signal/image analysis, machine learning, clinical neuroscience, and brain mapping methods (EEG & MRI) to examine developmental and physiological processes occurring in the brain and body. He has developed several prognostic biomarkers in a range of health and disease settings across the lifespan.
