Who We Are

Signe Bray, PhD

Signe Bray uses functional and structural magnetic resonance imaging (MRI) to study learning and cognition with a focus on understanding typical and atypical cognitive development and the effects of neurodevelopmental disorders on the brain. She has a BASc in Computer Engineering from the University of Waterloo, a PhD in Computation and Neural Systems at the California Institute of Technology and completed a post-doctoral fellowship at the Center for Interdisciplinary Brain Sciences Research at Stanford University.

Bray is currently seeking students and fellows with interests in 1) the development of advanced techniques for analysis of functional neuroimaging data, 2) structural and functional brain development, and 3) the study of learning and plasticity in neurodevelopmental disorders such as autism spectrum disorders.

Catherine Lebel, PhD

Catherine Lebel specializes in the use of magnetic resonance imaging (MRI) to study brain structure and function in kids. Much of her work has used diffusion tensor imaging (DTI), an advanced MRI technique, to assess white matter microstructure. Specifically, her research interests include brain plasticity in response to learning, treatment or intervention, and brain maturation in children with developmental disorders such as fetal alcohol spectrum disorder (FASD) and autism spectrum disorder (ASD). 

Her primary objective is to provide a better understanding of brain structure, function, and plasticity with the hope of improving, delivering, and monitoring treatment for kids with learning and behavioural challenges. She is currently recruiting students and fellows interested in studying brain development in pediatric populations.

Ashley Harris, PhD

Ashley Harris develops magnetic resonance imaging and spectroscopy methods for clinical and neurosciences research.  She is interested in using MR to understand brain neurochemistry, function and structure, as measured using different MR modalities.  Further, she wants to understand the relationship between these measures in both healthy brain function and clinical conditions including developmental disorders, neurodegeneration, injury and chronic pain.

Frank MacMaster, PhD

Frank MacMaster's research interest focuses on the neurobiology of mental health in children and adolescents, with a core focus on mood disorders. Previously, Dr. MacMaster has found changes in brain structure and function, particularly in the prefrontal cortex and hippocampus, in adolescents with major depression as compared to healthy controls.

MacMaster's aim at this next stage of research is to examine the neurobiology of emotional regulation and the interplay with stress in these populations. Investigative tools include functional magnetic resonance imaging (fMRI), magnetic resonance spectroscopy (MRS - proton and phosphorus), anatomical MRI, diffusion tensor imaging and cortisol concentration.
