Dr Daniel TozerUniversity positionSenior Research Associate Dr Daniel Tozer is pleased to consider applications from prospective PhD students. DepartmentsDepartment of Clinical Neurosciences Research ThemesInterestsI use MRI and associated image processing techniques to investigate stroke and small vessel disease. I am interested in the application of quantitative MR techniques to neurological conditions and developing image processing tools to meet this aim. Research Focus
