Profile

I joined the Information Resources Group, HEDS in April 2015 and my role is currently focused on information retrieval for systematic reviews.

After completing an MSc in Information Management at the ±¬ÁÏTV’s , I specialised as an academic liaison librarian supporting nursing and allied health; originally at the School of Nursing and Midwifery, before moving on to Sheffield Hallam University and the University of Leeds. In 2012 I completed a teaching qualification leading to accreditation as an Associate of the Higher Education Academy.

I enjoy teaching and my role at ScHARR allows me to continue this alongside a greater involvement in research.
