Dr Jonathan Godfrey BBS, BSc, MInfSc, PhD

Senior Lecturer

Institute of Fundamental Sciences

Jonathan's research is focused on the needs of the thousands of blind people around the world who need additional tools to make the visual elements of statistical thinking and practice less of a barrier. He also engages with staff and postgraduate students on campus who need statistical advice, which then involves linking the client with a postgraduate student from Statistics.
