Prof Toefy

img bio walker My postgraduate studies were on Foraminifera (masters on taxonomy) and its use as bioindicators for marine pollution mostly that of trace metals (PhD). As such, I have a keen interest in marine pollution studies and have collaborated with other researchers at CPUT on various projects in marine pollution. I also have training in general Marine Ecology and Biodiversity, which has enabled me to co-investigate projects in these topics. I have more recently been involved in aquaculture studies and my interest in this field has grown tremendously as I see this as one of the key industries which will drive food security in this country.
