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 takes 70 first-year students to the USA

The University of the Free State (UFS) has announced the names of the first ever group of 70 first-year students that will travel to the United States of America (USA) as part of the university’s Student Leadership Development Programme.

This group of students will spend two weeks at universities in the USA to experience student life and learn about leadership and diversity at these universities.

“This is a first for not only the UFS, but also for South Africa and we are incredibly proud. The programme is unique to any other student leadership development programme in the country. We are leading the way and are taking students to live and learn amongst students at various universities across the USA,” said Mr Rudi Buys, Dean of Student Affairs at the UFS.

The programme was one of the goals of Prof. Jonathan Jansen, Rector and Vice-Chancellor of the UFS, which he aimed to realise when he was appointed by the UFS in 2009.

“With the programme we want to develop participants’ thinking and capacity to lead in the contexts of diversity and change and we hope to direct them to programmes leading change in student life in general upon their return,” Mr Buys said.

The 70 students will leave for the USA on 22 September 2010. After spending some time there and learning more about their American peers’ lives and culture, they will return to the UFS on 7 October 2010.

“We took great care in selecting the 70 participants. They are representative of all our students, as well as students from our Qwaqwa Campus,” said Mr Buys.

A rigorous selection process was followed, which focused on the students’ academic excellence, their participation in student- and residence-life programmes and their interest in growing in the areas of, amongst others, leadership, diversity and citizenship. Each candidate had to undergo a pre-selection process, followed by a panel interview consisting of staff from various faculties and divisions at the UFS.

The students will stay in groups of about ten at the various universities, which include universities such as Cornell University, New York University, the University of Massachusetts, the Appalachian State University and Virginia Polytechnic University. “These universities will provide our students with accommodation and will present various academic and cultural programmes which our students will participate in and learn from,” said Mr Buys.

“We have also put a programme in place to prepare our students thoroughly for the trip. Because some of them have never travelled on an aeroplane, let alone travelled to a foreign country, we have made arrangements with the Department of Home Affairs for assistance with travel documentation, as well as special arrangements with the USA Embassy for assistance with visas. They will also be attending workshops focusing on, amongst others, research, leadership and diversity before their departure on 22 September 2010.

“Upon their arrival in the USA the group of students will firstly be taken to Washington DC where they will be briefed about American customs, etc. From there they will be placed at the various universities,” said Mr Buys.

Upon their return the students must be involved in student-life programmes on campus, establish volunteer programmes and initiate and establish mentoring programmes for their fellow students. “We want them to give back what they have learnt and experienced,” said Mr Buys.

“We are planning on implementing the Student Leadership Development Programme as an annual programme and are looking forward to this incredible programme through which this group of first-year students will have the opportunity of a lifetime to be true ambassadors of South Africa and, in particular, the UFS, as they leave for the USA,” he said.
