Prof Felicity Burt is a passionate virologist with more than 25 years of research on medically significant viruses that cycle in nature and are transmitted to humans via mosquitoes, ticks, or animals.

Prof Felicity Burt, an expert in arbovirology in the Division of Virology, has been leading the University of the Free State (UFS) COVID-19 Task Team over the past five months. Prof Burt is a passionate virologist with more than 25 years of research on medically significant viruses that cycle in nature and are transmitted to humans via mosquitoes, ticks, or animals.

As the UFS is celebrating its champion women this Women’s Month, Prof Burt gives us some insight into who she is. 

Please tell us about yourself

I am an arbovirologist from the Division of Virology in the Faculty of Health Sciences, and the National Health Laboratory Service. Who am I? I am a mum, a wife, a daughter, a sister, a sister-in-law, a friend, a scientist, a colleague, a professor.  I am passionate about my work and have spent more than 25 years researching medically significant viruses that cycle in nature and are transmitted to humans via mosquitoes, ticks, or animals. 
My research group investigates the various mechanisms that viruses use to cause disease, and I am particularly interested in how our bodies respond to infection that can help us develop vaccines or therapies. Raising awareness of these viruses, profiling disease associated with different viruses, and developing tools for surveillance programmes all contribute towards understanding pathogens and the public-health implications. I am so grateful for the opportunities my career has provided me, which includes travelling all over the world for conferences and meetings and participating in outbreak responses in Africa.   
   
Is there a woman who inspires you and who you would like to celebrate this Women’s Month, and why?

I am inspired by all women who set goals and work to achieve them. The goals may vary, but they are important and challenging to each individual.  Hence, I would like us to acknowledge and celebrate all women who achieve their goals through hard work, dedication, and of course, plenty of passion. 

What are some of the challenges you’ve faced in your life that have made you a better woman?

I have always been quite a shy person and still find it challenging to stand up in front of an audience. I was born in Zimbabwe and when I finished school, I moved to South Africa to study at the University of the Witwatersrand. Moving on my own to Johannesburg at the age of 18 was definitely a challenge for a quiet, reserved girl from Harare. Compared to home, Johannesburg was a mammoth city; however, I absolutely loved university life, met people who became lifelong friends, and pursued a career in science. I try to learn from my many mistakes and treat others how I would like to be treated, especially with kindness. 

What advice would you give to the 15-year-old you?

Dream on girl, and it doesn’t matter if they don’t all come true; life isn’t going to turn out as expected, but as long as you enjoy the journey. You don’t have to be the best, but you have to do your best – with passion of course. 

What would you say makes you a champion woman [of the UFS]?

To be honest, I wouldn’t call myself a champion, but I am quite proud of what I have established at the UFS. With hard work and passion, contributions from colleagues, support from management, and never forgetting a whole bunch of wonderfully enthusiastic students, we have built an active postgraduate research group, graduated multiple students, published scientific articles in international journals, presented our research at conferences, contributed to community engagement, had fun, and still have plenty more to achieve!

Einstein's gravitational waves as creative as Bach's music, says UFS physicist

Profile of the gravitational waves of the colliding black holes.

Prof Pieter Meintjes, Affiliated Researcher in the Department of Physics at the University of the Free State, welcomed the work done by the Laser Interferometer Gravitational-Wave Observatory (LIGO) science team.
 
For the first time, researchers from two of the American Ligo centres, in Washington and Louisiana respectively, observed gravitational waves directly, 100 years after Albert Einstein said they existed. "My study field in astrophysics involves relativistic systems. Therefore, Einstein's view of gravity is crucial to me. I consider the theory as the highest form of human creativity - just like the music of JS Bach. Over the past 100 years, the theory has been tested through various experiments and in different ways.
 
“The discovery of gravitational waves was the last hurdle to overcome in making this absolutely unfaltering. I am therefore thrilled by the discovery. It is absolutely astounding to imagine that the equations used to make the predictions about the gravitational-wave emissions when two gravitational whirlpools collide - as discovered on 14 September 2015 by LIGO - are basically Einstein's original equations that were published way back in 1916 - in other words, 100 years ago.
 
“The LIGO detectors have been operational since the early 1990s, but they had to undergo several stages of upgrades before being sensitive enough to make detections. LIGO is currently in its final stage, and is expected to function at optimal sensitivity only within a year or two. To be able to conduct the measurements at this stage is therefore a fantastic achievement, since much more funding will certainly be deposited in the project,” Prof Meintjes says.

The search for gravitational waves by means of the Square Kilometre Array (SKA) is one of the focus points in research by both Prof Meintjes and PhD student, Jacques Maritz. This involves the study of radio signals from pulsars that might show signs of effects by gravitational waves. They are looking for signs of gravitational waves. The gravitational waves discovered and studied in this manner would naturally vary much more slowly than the signal discovered from the two colliding gravitational waves.
 
The discovery will definitely provide renewed impetus to the Square Kilometre Array (SKA) Project to use the dispersion of pulsar signals, and to search for the impact of gravitational waves on signals as they travel through the universe. According to Prof Meintjes, the SKA will definitely contribute fundamentally to the Frontier research, which will provide a good deal of publicity for the UFS and South Africa, if significant contributions are made by local researchers in this field.
