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.

Nat Nakasa the inspiration behind UFS academic’s PhD thesis

“I’m interested in alternative ways of approaching things, so I wanted to look at how journalism can be used in an unconventional way to contribute to a developing society.”

This is why Dr Willemien Marais, a lecturer in the Department of Communication Science at the University of the Free State (UFS), decided to title her thesis: Nat Nakasa as existential journalist, describing a form of journalism that places emphasis on the individual’s experiences.

“Existentialism is a philosophy that provides scope for an individual approach to life, and I like Nat Nakasa’s writing because of his excellent sense of humour despite his horrific circumstances as a black journalist during apartheid,” she says.

A practical approach to writing

Dr Marais analysed Nat Nakasa’s approach to journalism through articles he wrote in the early 1960s. She searched for relevant themes of existentialist philosophy in Nakasa’s work in order to prove that he could be read as an existential journalist.

She mentions that in terms of contemporary relevance, Nakasa’s approach to journalism suggests that existentialism could provide the journalist with a practical approach to writing, especially for those journalists working in developing societies.

“The relevance of this approach lies in the fact that any society is always between things – the old and the new – which might require the journalist to operate outside the boundaries of conventional journalism.”

This study was qualitative in nature because of the interpretation required. She mentions that it was basically one of many possible interpretations of Nakasa’s work; with this one using existentialism as a lens.

An intellectually stimulating thesis

Dr Marais quotes French existentialist Jean-Paul Sartre, who said that interpreting someone’s work, especially someone who was no longer alive, was open to “thousands of shimmering, iridescent, relevant meanings”, and her research represents one of these possible meanings of Nakasa’s work as a journalist.

When asked how long she had worked on her thesis, Dr Marais simply answered “too long!” She mentions that her thesis was initially more of an intellectual exercise. Whereas the actual act of writing took about four months, she spent many years thinking about the topic. “Now that all is said and done, I realise I had to grow into the topic. It took me a while to realise that true understanding does not come overnight!”

Dr Marais mentions that other than herself and the work of Nat Nakasa, there were no other roleplayers involved. “For many, many years it was just Nat Nakasa and I. It was frustrating and exhilarating all at the same time.”
