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.

The Council of the University of the Free State (UFS) approved the appointment of Prof Prakash Naidoo as Vice-Rector: Operations, during its quarterly meeting held on the South Campus in Bloemfontein on 8 September 2017.

Prof Naidoo is a former Deputy Vice-Chancellor: Resources and Planning at the Vaal University of Technology (VUT). He has also been the Executive Dean: Faculty of Management Sciences at VUT. Prior to this, he was a lecturer in the Department of Accounting at the Durban University of Technology (DUT), and Vice-Dean and Acting Dean of the Faculty of Commerce at DUT.
“Prof Naidoo is a seasoned senior manager and an excellent appointment in this vital position. He understands the higher-education sector, and the Council is satisfied by the quality and extent of experience which he will bring to the position,” said Mr Willem Louw, Chairperson of the UFS Council. 

He holds a PhD in Management Accounting, MComm in Management Accounting, Honours in Accounting, Honours in Economics, BComm (Acc), and a University Diploma in Education.

Prof Naidoo is a registered professional accountant with the South African Institute of Professional Accountants (SAIPA), an associate of the Chartered Institute of Business Management (CIBM), and an Internationally Certified Fraud Examiner (ACFE). He was also an international associate of the American Institute of Certified Public Accountants (AICPA).
He served as member and chairperson on various boards and forums, including the Investment Committee of the National Tertiary Retirement Fund (NTRF); Audit Committee of the National Institute on Higher Education in Mpumalanga (NIHE); Audit Committee of the Higher Education Purchasing Consortium (PURCO), and other task teams in higher education. He also served as a former director of ACFE (SA Chapter), where he received a commendation for his work in fighting fraud and corruption in the country. He has written and published numerous papers, supervised research, presented papers at conferences, and published one book.
Prof Naidoo is currently the Campus Principal of the university’s Qwaqwa Campus. He will start in the new position as from 1 January 2018, following the subsequent retirement of Prof Nicky Morgan, current Vice-Rector: Operations at the end of December 2017.
