I am currently a postdoc researcher working with the Human Brain Project (EU Flagship project for brain research, cognitive neuroscience, and other brain-inspired sciences) and the UK7T Network (a collaborative network of all 7T MRI sites in the UK). I am interested in what predictive and contextual information channels exist within cortex, and how these channels interact with feedforward sensory input channels to create coherent perception. We approach this problem by experimentally isolating feedback signals while measuring brain activity using high-resolution, ultra high-field functional MRI. We then compare fMRI activity and models to understand what types of information are transmitted via feedback. After graduating in 2009 from the University of Southern California (Los Angeles, CA, USA) with a BA in Neuroscience, I worked in the Laboratory of Molecular Neuroimaging (UCLA), under Prof. Edythe London. In 2013, I moved to Glasgow to pursue my MSc and PhD under Prof. Lars Muckli.
