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.

NBT tests compulsory for all prospective students of the Faculty of Health Sciences at the UFS
2010-05-21

All prospective students who apply for study in the Faculty of Health Sciences (excluding Nursing) at the University of the Free State in 2011, must undergo die National Benchmark Tests (NBT) on 17 July 2010 or 31 July 2010.

Students who do not have an NBT test result will not be considered for selection at the Faculty of Health Sciences. The Health Sciences Placement Tests (HSPT) has been replaced by the NBT.

Applications for selection for 2011 close on 28 May 2010. A student who has not undergone the test will not be considered for selection and no exceptions will be allowed. If a student therefore does not undergo the test on 17 July 2010 or 31 July 2010, the university will not have the results in September 2010 before the preliminary selection takes place.

Prospective students who have undergone the test before 2010 will have to write the test again. Only students who have undergone the NBT in 2010 needn’t write the test again, but they have to fax their NBT reference number to 051 401 3226.

Prospective students have to register at www.nbt.ac.za  themselves and undergo the test. The cost of writing the test is R110.

The NBT is used by all universities in South Africa to improve the quality of education and learning in order to enhance the performance of students.

Students may visit the www.nbt.ac.za  web page for any further enquiries. Enquiries about applications en selection to the Faculty of Health Sciences at the UFS may be directed at AdminFHS@ufs.ac.za  or feel free to visit the UFS web page at www.ufs.ac.za/HealthSelection  . Students are requested to read the question-and-answer section regarding selection.
