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’ position on student politics
2011-09-01

The University of the Free State (UFS) welcomes politics on its campus. It especially invites students to participate in all the political activities on campus, ranging from seminars and debates on national and provincial politics, and organization within party political structures. Earlier the year, in the run-up to the Local Government Elections, a programme was run on campus with all political parties participating in public and radio debates with students on political issues.

A university must be a place for all kinds of ideas and organizations---social, cultural, religious, academic and, yes, political. The perception that the UFS has “banned” politics is simply not true, nor is it possible within a constitutional democracy.
 
The University of the Free State once again invites SASCO and any other political groupings that have not yet registered to participate in campus life, to do so as soon as possible. It is important to the UFS that all student bodies enjoy full participation in campus life, and that there exists a vibrant and exciting political life on the campus alongside academic, social, cultural and religious life.
 
The Student Representative Council (SRC) Elections at the UFS has been constituted on independent candidacy and non-party-political basis. This is a decision crafted and recommended by the Broad Student Transformation Forum, whose members are elected by students, and approved for implementation by the highest authority of the university, the Council. The decisions of the Student Forum entails that all students can nominate individuals for a variety of student leadership positions, which includes nomination for elective portfolios in the SRC elections, but also within nine sub-councils that hold ex-officio seats on the SRC.
 
The old system which restricted student leadership to representation on a party-political basis only (DA, ANC, Freedom Front Plus etc) no longer exists.
 
This decision of the Student Forum ensures that the rights of all students to directly elect their representatives are protected, and that the SRC in fact represents the student body as a whole and not particular interest groups alone. This decision enables ALL students to stand for and participate in campus politics in the SRC elections, though not on a party political ticket. In the 2011 SRC Elections, for example, SASCO members were indeed mandated by its local branch to stand as candidates for various elected positions, as did other political parties such as the DA Student Organisation, a development which the university welcomes. 
 
Most importantly, the UFS insists that all students participate in university life with respect for the rights of all students, irrespective of their social beliefs or political commitments. The UFS insists that no student or student grouping acts to disrupt campus life or insult university staff or denigrate fellow students on grounds of race, religion, language, gender, etc. This is very important to the UFS as it works to build a non-racial culture that respects our common humanity. Our students must learn that democracy and decency go hand in hand, and that part of learning at a university, is to learn to differ without resorting to a language of derision.
 
In short, the University of the Free State warmly welcomes full participation in politics, as in other spheres of student life, on all three its campuses.
