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.

UFS awarded tenders worth R22,5 million for Maths and Science teacher-training
2010-03-17

The Centre for Education Development (CED) at the University of the Free State (UFS) has received tenders worth about R22,5 million over the past two years from four provinces to train Mathematics and Science teachers from underperforming schools.

The CED has received tenders from the following provincial departments of education: Free State, Northern Cape, North West and Mpumalanga.

“The centre has a good reputation for the training of teachers in these disciplines and has been involved with the upgrading of Maths and Science teachers for at least 15 years,” said Prof. Daniella Coetzee, Director of the CED.

It is currently busy with the training of North West teachers after being awarded a R13,5 million tender by the Province as part of its quest to improve pass rates in Mathematics and Natural and Physical Sciences in underperforming schools.

“The tender is for the upgrading of the knowledge and methodology of teachers for Mathematics and Natural and Physical Science, as well as the upgrading of the knowledge of subject specialists in the North West Province,” said Prof. Coetzee.

For this project the centre trains 1 000 teachers and 90 subject specialists from underperforming schools over a period of three years.

The programme commenced in February this year with a baseline assessment of the teachers to determine knowledge and methodology gaps upon which to focus in the training.

“After the programme has been completed we will also do a post-assessment to see if there had been progress,” she said.

The training is offered only on Saturdays at Vryburg, Klerksdorp, Makapanstad, Brits and Zeerust and is presented by lecturers from the CED as well as selected and trained tutors from the North West province.

“We have successfully completed another Maths, Science and Technology project for the North West Department of Education. We have also completed similar projects for the Northern Cape and one for the Free State Department of Education,” she said.

These completed projects entailed formal qualifications (Advanced Certificate in Education) in Maths, Science and Technology and were worth in excess of R5 million.

The CED has just been recently awarded yet another tender in excess of R4 million over a period of two years by the Mpumalanga Department of Education.

Prof. Coetzee had the following to say about the CED being the preferred choice of these provincial Departments of Education: “It has to do with the fact that the CED has been performing well with the upgrading of teachers. It has proven itself as a leader in the in-service training of Maths and Science teachers in South Africa.”
