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.

With the recent procurement of SAB by Anheuser-Busch InBev SA/NV (AB InBev), a Belgian transnational beverage and brewing company, the 500L educational brewery located at the SAB Cyril Ramaphosa World of Learning, became available for donation. After an initial shortlisting of three universities, the SAB World of Learning Brewery was awarded to the University of the Free State (UFS) to be managed by Kovsie Brewing.

Prof Corli Witthuhn, Vice-Rector: Research at the UFS, approved the application for a micro-manufacturing liquor licence right in the middle of campus, which effectively put the UFS bid in a class of its own. It is part of her vision that entrepreneurial activities must be visible on campus”

Sixteen universities were approached to obtain the brewery for their respective campuses.

Kovsie Brewing is an initiative started by postgraduate students at the UFS Department of Microbial, Biochemical and Food Biotechnology in 2012. The main objective of this initiative was to expose BSc students to brewing as a practical application of the scientific fields presented at the department.

Kovsie Brewery entered into
the yearly  SAB Intervarsity
Brewing Competition. Kovsie
Brewing has won the best label
competition in 2013, 2014 and 2015
and was placed in the top three in
2016 and 2017.


First brewing and fermentation school
Dr Errol Cason, project leader at Kovsie Brewery, said: “Over the past five years the small-scale experimental brewery has steadily grown to the point where we obtained institutional support to establish the first Brewing and Fermentation School at the university.

Dr Cason explains that the primary role of Kovsie Brewing is to establish an accredited fermentation-based curriculum at the UFS to educate undergraduate and postgraduate students in the scientific process involved in the production of beer. “In addition, the donation enables Kovsie Brewing to provide practical job-related training and skills development on industrial grade equipment,” he said.

Emphasis on entrepreneurship
The secondary role is for Kovsie Brewing to function as a multi-disciplinary platform to stimulate the interaction between students from various fields of study. Currently Kovsie Brewing has well-established cooperative projects with both Marketing and Entrepreneurship programmes.

“In the future, Kovsie Brewing will expand on these multi-disciplinary interactions by incorporating other departments of the UFS with the focus on product development, logistics, as well as the legal aspects concerned with brewing,” Dr Jan-G Vermeulen from the Kovsie Brewery team said.

Corporate social investment representatives from AB InBev recently visited the university. Among others they met Drs Vermeulen and Cason. During their visit they also looked at other university projects, including the Department of Paediatric and Child Health and the Universitas Hospital, the Engineering Sciences Department and the Naval Hill Planetarium.

Khosi Mogotsi from AB InBev said: “It was wonderful to experience the passion with which UFS staff do their work.”
