I am a senior researcher based at the Evolutionary Studies Institute, University of the Witwatersrand with previous employment as a Scientist at the Council for Geoscience. Additionally, I am a stratigrapher with the South African Committee for Stratigraphy and an associate stratigrapher with the Subcommission for Devonian Stratigraphy (International Union for Stratigraphy) where I am the South African representative. My research interests are focused towards understanding palaeoenvironments, palaeoecology and palaeogeography of Devonian high latitude (subpolar-polar) regions, as well as the proxies for palaeoenvironmental and palaeoecological change through time in these regions. As such, I am specialised in sedimentology, invertebrate palaeontology, lithostratigraphy, biostratigraphy, sequence stratigraphy, ichnology, tectonics and geochronology. I also "dabble" in historical geology with focus on documentation of pre- and early-colonial interest in fossils from the Cape Supergroup as well as promotion of geo- and palaeoheritage of the Cederberg.
