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.

A bridge to the future for school leavers

Thousands of learners in the country’s high schools fail to qualify for post-school education and training. Now a unique project funded by the Ford Foundation and being piloted at the University of the Free State (UFS) seeks to provide such learners with a lifeline.

The 2008 Grade 12 results showed once again that the schooling system is – and has been for a long time – in the throes of a severe crisis. The most disturbing feature of this crisis is that the system does not produce learners with the required level of literacy, numeracy and other cognitive skills to further their education or to become part of the country’s workforce.

Clearly this situation is untenable in a developing country such as ours, facing the immense challenges of a severe skills shortage, poverty and unemployment. We cannot afford to have hundreds of thousands of young people walking the streets without any prospect of a decent living and a future of opportunity.

The UFS and partners in the Free State Higher Education Consortium (FSHEC) have devised a unique programme to help underprepared and even unprepared school-leavers who have fallen through the cracks of the school system.

“We are hoping to make a meaningful contribution to the challenging field of creating educational opportunities for post-school study and the world of work through the generous support of the Ford Foundation,” says Ms Merridy Wilson-Strydom, Research Consultant at the Centre for Higher Education Studies and Development at the UFS.

“The Skills for a Changing World Programme is specifically aimed at removing barriers to educational opportunities for school-leavers who are not able to access higher education – mainstream or extended degrees. At the moment there are few, if any, meaningful opportunities for those learners who come through the school system un/underprepared,” she says.

The primary target group for the NQF Level-5 Programme is young people between the ages of 18 and 25 who are currently excluded from post-schooling educational opportunities. The duration of the programme is one year.

According to Ms Wilson-Strydom, the core modules of the activity-driven curriculum are English Literacy and Language Development, Mathematical Literacy, Information and Communication Technology and Your Global Positioning System (YGPS), which focuses on study skills and critical life skills, e.g. dealing with diversity. Students will also be supported to make informed choices about their future study or career directions.

“The development of the core-module materials is almost complete and from the second semester we plan to test the programme by means of a pilot project, which will be conducted on the UFS’s South Campus in Bloemfontein,” says Ms Wilson-Strydom.

“The pilot study will involve a group of 20-50 learners who have finished Grade 12 but do not qualify for the UFS bridging programme known as the Career Preparation Programme or any other higher-education programmes,” says Ms Wilson-Strydom.

Although not yet accredited, the project team aims to have the programme accredited as a Higher Certificate and is also exploring the possibility of registering the programme as a Short Learning Programme.

“One of the challenges with access and bridging programmes in the country is that students do not obtain a formal qualification for their bridging year. Hence those who do not continue with higher-education study (or cannot continue for various reasons such as finances), do not gain the recognition they should get for what they have learnt during their bridging year.”

“Our focus on developing the Skills for a Changing World Programme as a qualification in its own right is a key innovation in the current education and training landscape,” says Ms Wilson-Strydom.
