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.

Open Day attracts thousands

“It is easier to pass Grade 12 today because we don’t have a standard. However, at the University of the Free State, standards are important.”

This was Prof. Jonathan Jansen, Vice-Chancellor and Rector of the UFS’ message when he addressed a packed Callie Human Centre on the Bloemfontein Campus during this year’s Open Day.

“This university is the jewel of the country. Here at Kovsies we take academic standards seriously. You must know who you are in a place where academic standards are extremely important. Anyone can obtain a degree, but here you can get more than a degree. You get an education,” he said to the more than 5 000 learners and parents from across the country.

“It is not only important that you study here in South Africa, but also in other countries. That is why our students study all over the world. You must think out of your comfort zone, have a big heart, achieve great heights and show everyone that you are a Kovsie.

But, it is not all about studying – it is also about being human and reaching out to others. When you come to this university, you will also do other things that will make you proud of being a Kovsie.

Quality looks for quality. Therefore, work hard and study hard because you need to be at a good university,” he said.

The programme consisted of, among others, a spectacular laser show, a performance by Bobby van Jaarsveld and special messages from DW Bester and Sannah Mokone, Rhodes Scholars currently studying at Oxford University in the United Kingdom.

In a pre-recorded message DW, a Ph.D. student in Mathematical Statistics, encouraged prospective students to work hard and persevere. Sannah, doing a Master’s degree in African Studies, said she believes in the future of the African continent. “I believe in our future students and know you can make it.”

Prof. Jansen also introduced some of the university’s recent student achievers such as Jurie Swart, regional winner of the Corobrik Architectural Student of the Year Award; Farzana Samuel, named by the Association of South African Quantity Surveyors (ASAQS) as the most outstanding student in quantity surveying for 2012; and Sibusiso Tshabalala, one of Google’s Top 10 Young Minds.

Richard Chemaly, President of the Central Student Representative Council (CSRC), said that, by coming to Kovsies, prospective students would become the best person they can be. “We have over 70 student organisations to help you take part in student life activities. So, make use of these opportunities,” he said.

The programme concluded with an introduction to the seven faculties by the respective deans.

The estimated 7 000 prospective students and their parents also had the opportunity to visit faculties and the stalls of residences.
