Profile
I am a South African citizen based in George, South Africa. I have received forestry qualifications from the Nelson Mandela Metropolitan University (N. Dip Forestry), University of Stellenbosch (BSc Forest Science) and the University of Pretoria (MSc Forest Science). I am currently completing my PhD at the University of Florence.
Research interests
I have a specific interest in harvesting machine technology used in forest growing plantation forestry. At a more focused level, this can be narrowed to the technology used to cost-effectively harvest Eucalyptus pulpwood, including coppiced stands. Further interests include productivity research in the harvesting fields.
