Biography

Dr Petronella Nel has received from the University of Melbourne:  a BSc (Honours), PhD (Chemistry), and MA (Cultural Materials Conservation).

Dr Petronella Nel is a lecturer and researcher at the Grimwade Centre for Cultural Materials Conservation. She is involved with the teaching and research programs at the Centre. Her research interests include the non-invasive analysis of artefacts, and the development of scientific techniques to conservation problems. More specifically her current research involves:  the analysis and assessment of adhesives used to repair archaeological pottery; conserving polymer based materials (like plastics and film) in museum collections; the elemental and mineralogical characterisation of ochre-earth pigments using PIXE, XRF, XRD and NAA; and the development of the Chemistry Collection at the University of Melbourne.
