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.

The UFS Debate Society is definitely not all talk and no action. They ranked 10th at the Southern African Development Community (SADC) Debate Open held in Gaborone, Botswana, from 14 – 16 November 2014.

Kovsie students Lehakoe Masedi (second-year BCom Law) and Matlhodi Leteane (first-year LLB Law) teamed up to represent our university at the prestigious SADC event hosted by the University of Botswana Speaking Union. Eight Southern African countries were represented as well as six universities from South Africa.

“Attending a tournament focused on the debating of regional issues and solutions was a great reward and we wish to take part in more of these tournaments in future,” says Lehakoe.

Out of a pool of 40 of the best individual speakers in Southern Africa, Lehakoe and Matlhodi were jointly awarded 18th place.

“Debate continues to help the growth of the student community and the attendance of such debate tournaments lends a lot of help to the internal growth of not only our partnership but our debate society as a whole,” says Lehakoe. “We take great pride in our performance, especially as first-year *British Parliamentary speakers. We wish to improve and grow as we progress further in our debate careers.”

*British Parliametary speaking is the style of debating used by university institutions.
