Kyla Dooley, runner-up in this year’s Three-minute thesis competition, wants to pursue a career working alongside police enforcement, using her knowledge of forensics to solve criminal cases and convict perpetrators.

When rapes and sexual assaults are committed, DNA evidence can play a large role in convicting the offenders. DNA evidence collected from sexual crimes can, according to Kyla Dooley, often be tricky to analyse.

Kyla has just completed her master’s degree, specialising in Forensic Genetics, at the University of the Free State (UFS). She not only thrives in this field – graduating at the top of the Faculty of Natural and Agricultural Sciences in 2018 when she was awarded the Dean’s Medal – but her work also brought her the runner-up position in this year’s Three-minute thesis competition. 

She talked about her research on the use of male-specific DNA in the analysis of DNA evidence collected after crimes of a sexual nature have been committed.

Explaining her research, Kyla elaborates: “In most cases, the victim is female, while the offender is male. Therefore, the evidence is often a mixture of male and female DNA and this can make it difficult to analyse the male DNA and match it to a male suspect.”

She believes the solution to this is to target male-specific DNA in analysis. “This eliminates all female DNA and simplifies the process,” says Kyla.

“Unfortunately, male-specific DNA technology is not currently used in South Africa, because the DNA regions tested to date haven’t shown much success in distinguishing between males in our population,” Kyla points out.

“The goal is now to use DNA evidence, to match it to a suspect, and have the confidence that it came from him and only him. Or else defence lawyers could argue that it came from someone else in the population,” she says.

Improving DNA evidence

Therefore, Kyla’s research focused on evaluating a new group of male-specific DNA regions, which are to be tested yet, to see if it would be a viable option for use in South Africa. 

“I achieved this by collecting DNA samples from men on campus, processing them to obtain DNA profiles, and then determining how well these regions can distinguish between the men. The results of my research demonstrate the potential of these DNA regions to improve the use of DNA evidence when investigating sexual assaults in South Africa,” says Kyla.

She believes her study can play a role in increasing the conviction rate of sexual offenders, which could lead to a reduction in South Africa’s alarmingly high rape statistic. 

“Everyone in South Africa is affected by this horrific crime in some way or another, so the benefits of this would be widespread,” she says.

Solving crimes

Although Kyla will one day pursue further studies, she is ready for the next stage in her life. “I am in the process of applying for jobs and getting ready to dive into the real world. I’ll definitely be pursuing a career working alongside police enforcement to solve criminal cases and convict perpetrators of such crimes. Working for the NYPD in the USA or Scotland Yard in the UK is the ultimate dream job,” she says.

“I chose my field not only because the forensics world absolutely fascinates me, but also because I want to make a difference. I want to play a role in getting justice for those affected by violent crimes. One simple process in a forensic scientist’s everyday routine could be a life changer for a victim of crime,” believes Kyla.

New schools, restructuring part of streamlined Faculty of Health Sciences

Numerous developments, such as the creation of two new schools and one newly restructured School of Medicine in the Faculty of Health Sciences at the University of the Free State (UFS), will catapult this renowned faculty to even greater heights.

Five-school structure to increase access
 
A five-school structure was proposed at the annual Faculty Management retreat in July 2016. The previous three-school model included the Schools of Medicine, Nursing, and Allied Health Professions.

The current School of Medicine has been restructured and will henceforth be known as the School of Clinical Medicine. The Schools of Pathology and Biomedical Sciences have been added to the faculty. “So, three new schools were in fact created within the faculty,” said Prof Gert van Zyl, Dean of the faculty.   

“There was also a request from the National Health Laboratory Services to group academics that is rendering services in pathology into a new School of Pathology.” This is what motivated the faculty management to create two new schools.

Esteemed academics appointed 

With the creation of the new schools, there were also new appointments within the Faculty of Health Sciences. Dr Jocelyn Naicker has been appointed as the new part-time Head of the School of Pathology, Prof Chris Viljoen was appointed as the part-time Head of the School of Biomedical Sciences, and Prof Nathaniel Mofolo as the new Head of the School of Clinical Medicine. Prof Santie van Vuuren remains Head of the School of Allied Health Professions, and Prof Magda Mulder as the head of the School of Nursing. 

Research outputs to remain as usual
The addition of the new schools will not impact research output. “In the past, research was done across departmental boundaries between all the departments in the faculty,” Prof Van Zyl said. The advantages of adding two additional schools are that the workload will be distributed among the five schools. The heads of schools will work within their respective disciplines and related areas, and will eliminate the duplication of administrative functions.
