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.

Department of Oncology provides hyperbaric chamber to cancer patients – a first in the Free State

Thanks to the Department of Oncology at the University of the Free State (UFS), cancer patients now have access to a hyperbaric chamber – a medical treatment that enhances the body’s healing process through the inhalation of oxygen.

In order to realise this tremendous addition to the treatment of cancer patients, the Department of Oncology established collaboration between the UFS School of Medicine, the Free State Department of Health, and a group of private donors. Currently the only one in the Free State, the hyperbaric chamber has been installed at the Oncology ward at National Hospital in Bloemfontein and will benefit not only patients from the Free State, but also the North West province and the Northern Cape.

While lying down in the chamber, the patient’s body absorbs more oxygen as a result of the high levels of air pressure. This process stimulates the healing of cancer wounds and various other injuries, including sports injuries.

Dr Alicia Sherriff, Head of the Department of Oncology (UFS), says her team is passionate about enhancing the quality of their patients’ lives, even when facing difficult circumstances. “I believe that the hyperbaric chamber is just one way of achieving this, since it helps decrease the harm done by certain medical conditions on the human body,” Dr Sherriff says.
