Dr Milton Mogotsi
Dr Milton Mogotsi graduated on Thursday with the degree Doctor of Philosophy with specialisation in Virology during the Faculty of Health Sciences at the University of the Free State (UFS) autumn graduation ceremonies.

A pilot study for his master’s degree not only ignited Dr Milton Mogotsi’s passion but he was also inspired by the fact that this was a newly emerging field of research in the discipline of virology at the time. This eventually led to him pursuing a PhD and ing on his research.

Dr Mogotsi graduated on Thursday (18 April) with the degree Doctor of Philosophy with specialisation in Virology during the Faculty of Health Sciences at the University of the Free State (UFS) autumn graduation ceremonies. Prof Martin Nyaga, Head of the Next Generation Sequencing Unit (UFS-NGS) and an associate professor in the Division of Virology, was his promotor and Prof Trudi O’Neill from the Department of Microbiology and Biochemistry his co-promotor.

“It feels great! It was exhausting and overwhelming at times, but that light at the end of the tunnel will start to be brighter. I feel so proud of myself and very free. Nothing beats that liberating feeling that I have successfully completed a doctoral degree and now a new chapter of my life begins. I believe this post-PhD period is an excellent time for reflecting on my attributes and revising my CV, and with a PhD degree under my belt, I look forward to an abundance of opportunities that will soon open up,” says Dr Mogotsi after graduating.

Research

According to him, he was first introduced into this research concept when he was doing his master’s degree in microbiology. “Although it was more of a pilot study aiming to assess the feasibility of conducting this type of research on a larger scale, we made some interesting findings which we published in an international journal.

“I obtained my degree with distinction, receiving an award for Best Master’s Dissertation in Microbiology. The findings of this research really ignited my passion, and I was also inspired by the fact that this was a newly emerging field of research in the discipline of virology at the time, and of course in my master’s research there were some gaps and limitations which needed to be addressed. I then took a decision to pursue a PhD and expand on that research, and working with new-born babies is always enjoyable,” says Dr Mogotsi. 

With his thesis titled “Longitudinal characterisation of the enteric virome of infants from the Free State, South Africa, using viral metagenomics”, Dr Mogotsi’s research aimed to characterise the total assemblage of all viruses that colonise the gastrointestinal tract of newborns, often referred to as the gut virome, using metagenomics.

“We know that the human gut undergoes some changes as the new-born baby becomes exposed to the numerous microorganisms, such as viruses, from the immediate environment. This once-in-a-lifetime occurrence can have life-long effects on the health and disease state of humans. Viral intestinal infections are among the leading causes of childhood hospitalisations and deaths, especially in Africa, and infants are at a greater risk of suffering severe illnesses due to their immature immune system,” he explains.

According to him, previous research had focused more on the investigating the population of bacteria present in the gut of new-borns, therefore, there’s a huge knowledge gap about viruses colonising this part of the human body. In South Africa, more attention has been on assessing the effectiveness of currently available vaccines and surveillance of specific disease-causing viruses such as rotavirus.

The research he was conducting, he continues, therefore, sought to characterise all intestinal viruses in healthy new-borns individuals, their source of origin, the changes in diversity and composition occurring over time, as well as their potential implications on the health of infants. “The findings of my study have provided more insights into what is known or new viruses are colonising the infants’ gut, as well as their evolution over time”, he adds.

PhD journey

Even though he had to put his PhD on hold for a year due to COVID-19, but with the resilience, persistence, and his ability to clear the roadblocks that were in his way, he managed to complete it. He also credits his supportive mentors and a community of colleagues and friends for their unwavering support throughout his academic journey.

“After a year-long delay, I was able to go ahead with the project and everything went well from sample collection and sample processing in the lab. The challenging part was analysing and interpreting the data as this involved advanced bioinformatics, but in the end, I was able to find solutions and make sense out of the results I got. The study was a great success with two publications in peer-reviewed international journals emanating from this study.

“Furthermore, I had an opportunity to present my research in local and international conferences. I have been to Ghana, Nigeria and Indonesia. Locally, I presented in a conference in Johannesburg and in Cape Town. More exciting was participating in the Three Minute Thesis (3MT) competition in which I emerged victorious, winning the National 3MT competition. The other award I received was from the Faculty of Health Sciences Research Forum, winning the Dr Lehlohonolo Mathengtheng Trophy for best PhD presentation”, says Dr Mogotsi.

Motivation

Dr Mogotsi says the fact that he comes from the township and received his secondary education from a township school always kept him motivated. He is well aware that there are many who look up to him, who are also inspired by what he has achieved.

“More importantly, my supervisor, Prof Nyaga, was very supportive and he is very active in his research field with genuine interest in student projects, while making time to provide adequate supervision and mentorship. His high standards of ensuring that students graduate with a strong publication record is commendable.”

As a coordinator of wet lab activities at the UFS-NGS Unit, Dr Mogotsi is currently involved in several projects as the unit is a World Health Organisation Collaborating Center for Vaccine Preventable Diseases and Pathogen Genomics. They are doing collaborative projects with several partners across the continent on the genomic surveillance of enteric viruses such as rotavirus, norovirus, sapovirus, astrovirus and adenoviruses.

“You cannot let your legacy stop here. Use your qualifications to change the life of others.”

This was the call from Dr Muavia Gallie, a guest speaker at one of the Autumn Graduations on the Bloemfontein Campus of the University of the Free State (UFS). He is a School-Turnaround strategist and educational activist.

He was the speaker on 12 April 2016 at the Faculty of Education graduation ceremony in the Callie Human Centre. According to Dr Gallie and other speakers at the graduations, graduates need to use their qualifications for the good of South Africa.

A diverse group of graduates

A total of 3681 qualifications were conferred in seven faculties between 12 and 15 April 2016, the week of ceremonies comprising eight sessions. It was four days of festivities with friends and families gathering to celebrate with graduates.

The large number of graduates consisted of a diverse group. According to Dr Khotso Mokhele, Chancellor of the UFS, the group passing with distinctions was also much more diverse than in past years, especially in the number of female students.

Prof Jonathan Jansen, Vice-Chancellor and Rector of the UFS, said graduation ceremonies remain the most special days on the UFS calendar.

A total of 22 students from the Center for Universal Access and Disability Support also graduated during the week.

Work for next generation

Sello Hatang, the speaker on 12 April 2016 at the Faculties of Health Sciences, Law, and Theology ceremony, echoed Dr Gallie’s sentiments; “As you leave this university, your work begins for the next generation; to serve the people you care about in any way possible,” said Hatang, the Chief Executive of the Nelson Mandela Foundation.

Other speakers included Dawie Roodt, the most referenced economist in the media in 2015, at the ceremony of the Faculty of Economic and Management Sciences on 14 April 2016. The speaker on 15 April 2016 at the ceremony of the Faculty of Humanities was Nikiwe Bikitsha, one of South Africa’s leading journalists and broadcasters.

Achievers

In the Faculty of Natural and Agricultural Sciences, Madri Brink (Baccalaureus Scientiae Agriculture) received a Senate Medal for the best four-year Baccalaureus degree, while Kyla Hayter (Baccalaureus Scientiae Honores) won the Senate Medal for the best Honours student at the UFS. Willem Carel Brink from the Faculty of Humanities received a Senate Medal for the best three-year Baccalaureus Degree.
