    Professor Guy Williams

    University Position
    Professor
    Professor Guy Williams is pleased to consider applications from prospective PhD students.

    Interests

    Our group's research interests lie broadly in nuclear magnetic resonance (NMR). This phenomenon allows data to be collected noninvasively on both the structure and function of the human brain. We research novel acquisition methods to provide contrasts relevant for neuroscience. As a group embedded in the WBIC, the common theme is to translate basic physics research into relevant tools for a range of neuroscience investigations. For example, we are developing and optimising pulse sequences for inferring the diffusion characteristics in the brain. These provide a useful tool for assessing tissue following head trauma and for dementia projects. We also have interests in novel MR acquisitions applied to psychology research areas such as learning and behaviour. Of equal importance is the subsequent processing and analysis of the acquired datasets, including machine learning approaches.
