Gavin Dollman
Gavin Dollman is involved in virtual prospecting for fossils using a drone.

Gavin Dollman is one of the young researchers selected for the international research programme funded through the US-SA Higher Education Network. This prestigious programme is aimed at giving PhD candidates and their supervisors the opportunity to regularly travel to the USA and spend time at participating US universities where their co-promoters will be based.

“The University Staff Doctoral Programme (USDP) has allowed me to bring my idea of collaborative science to fruition. It’s an exciting opportunity,” Dollman said.

Dollman added that his PhD studies would focus on the machine and deep learning for prospecting for palaeontology. He is studying with the Appalachian State University. Other participating universities are Montana and Colorado State.

He has also had the privilege to work alongside a team of Geologists and Paleontologists from the universities of Birmingham, Zurich and Oxford in a project under the auspices of the University of the Witwatersrand’s Evolution Studies Institute (ESI) on a site in rural Eastern Cape.

“My role within this massive project is to perform a detailed survey of the sites and the surrounding area for later analysis. I used a drone known as the DJI Phantom 3 Pro with which I took hundreds of pictures that were later put together to create a detailed map,” he said.

“The maps allowed for virtual prospecting by the team and will in the long term serve as the basis for a predictive fossil model for the area.”

Dollman is a lecturer in the Department of Computer Science and Informatics on the Qwaqwa Campus.

The impact of personal care products on water resources in the Free State

Water is of the utmost importance in personal hygiene. Most people can hardly have a day go by without taking a shower in the morning and at night. However, it is this very habit that is increasingly polluting the water resources in South Africa.

Contaminants found in pharmaceutical and personal care products have been accumulating in water masses in recent years. These contaminants especially refer to hormones in medication, as well as colouring agents and fragrances used in soap, shampoo and body lotions.

“Little information and data are available on the prevalence of these contaminants, and on how high the level of pollution really is,” says Jou-an Chen, researcher in the Department of Microbial, Biochemical and Food Biotechnology at the UFS.

Her research particularly focuses on the prevalence and impact of those contaminants.

“Because these substances have not been properly investigated, we are not sure how widely it occurs and whether it is harmful to the environment. It was precisely the lack of information that has inspired me to investigate further.”

“If we could identify the contaminants and what it is doing to the environment, it could make a valuable contribution to directives on water quality standards.”
