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.

Renowned forensic scientist speaks at the UFS

It is necessary for more research to be done in the field of forensic science in South Africa. This is according to Dr David Klatzow, well-known forensic scientist, during a lecture delivered at the University of the Free State (UFS) last week.

The university is offering, for the first time this year, a BSc degree in Forensic Science in the Department of Genetics. This three-year degree is, among others, directed at people working for the South African Police Service on crime scenes and on criminal cases in forensic laboratories. Students can also study up to PhD level, specialising in various forensic fields.

There is no accredited forensic laboratory in South Africa. “It is time to look differently at forensic science, and to deliver research papers on the subject. In light of the manner in which science is applied, we have to look differently at everything,” Dr Klatzow said.

Dr Klatzow praised the university for its chemistry-based course. “Chemistry is a strong basis for forensic science,” he said.

A paradigm shift in terms of forensic science is needed. Micro scratches on bullets, fingerprints, DNA, bite marks – all of these are forensic evidence that in the past led to people being wrongfully hanged. This evidence is not necessarily the alpha and omega of forensic science today. DNA, which seems to be the golden rule, can produce problems in itself. Because a person leaves DNA in his fingerprint, it is possible that DNA is transferred from one crime scene to another by forensic experts dusting for fingerprints. According to Dr Klatzow, this is only one of the problems that could be experienced with DNA evidence.

“No single set of forensic evidence is 100% effective or without problems. Rather approach the crime scene through a combination of evidence, by collecting fingerprints, DNA, etc. It is also very important to look at the context in which the events happened.

“A person sees what he expects to see. This causes huge problems in terms of forensic science. For example, if a criminal fits the profile of the perpetrator, it doesn’t follow that this specific criminal is the culprit. It isn’t what we don’t know that gives us trouble, it’s what we know that isn’t so,” Dr Klatzow said.
