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.

“Our education system needs quality teacher education.”

This was the message from Prof Jean Baxen, Deputy Dean of Research at Rhodes University in Grahamstown. She delivered the Education Public Lecture on ‘The lives of children, citizenship and teacher education: challenges and opportunities’ at the University of the Free State’s Bloemfontein Campus.

Growing up in White River, the rural areas of Eastern Transvaal (as it was previously known), Prof Baxen took the audience on a journey of the imagination. She shared stories of how she and fellow learners walked miles to get to school and how her son found himself in a situation of being unsure about his own racial identity, questioning what it meant to be ‘coloured’. She also related stories of how teachers are not sufficiently prepared to mediate information on HIV/Aids.

These stories revealed how little teachers cared, and also how difficult and challenging it is for learners to cope in such teaching and learning environments – thus calling for quality teacher education.

She stressed the fact that quality teacher education is needed in South Africa to assist in curbing the challenges children and fellow citizens come across in our broader society. “It is important that, as teacher educators, we should groom teachers to find and understand their identity, sexuality, and also the world they live in. There is an urgent need for us to hold ourselves and others accountable and to not distance ourselves and make it someone else’s responsibility – it is our joint responsibility as citizens,” she said.

We need a pedagogy that would navigate and start formulating a language that we could use to face these challenges, she proposed.
