    Professor Roger Barker

    (he/him/his)
    University Position
    Professor
    Professor Roger Barker is pleased to consider applications from prospective PhD students.

    Interests

    I work on: Clinical aspects of Parkinson's and Huntington's disease including the study of disease heterogeneity using cognitive testing, functional imaging and genetic biomarkers. Examining the value of different biomarkers to assess disease onset and progression. Evaluating and developing novel therapies for these conditions including ATMPs and especially stem cell therapies for Parkinson's Disease.. Studying the cell biology of neurodegenerative disorders.
