Our podcast guest
Prof Jeandrew Brink holds the post of Associate Professor in the Department of Mathematics and Applied
Mathematics within the Faculty of Natural and Agricultural Sciences at the University of the Free State. Her areas of interest include an analytical interest in Einstein field equations, dynamical systems, algorithms for testing general relativity
and the no-hair theorems, black holes, and gravitational waves. Prof Brink registered for a Bachelor of Sciences in 1998, continued with honours studies in 1999, and completed her master’s degree in 2000. Prof Brink’s research is on various
theoretical aspects of testing general relativity. She is a member of the MeerKAT telescope team that times and detect pulsars. She is also working with members of the Laser Interferometer Gravitational-Wave Observatory (LIGO) to find ways of using
gravitational waves to test Einstein’s theory.
Prof Brink was involved in the compilation of a video of geodesic orbits around a Manko-Novikov singularity, selected to be part of a Starmus 3 concert, the proceeds of which went towards promoting the Stephen Hawking Medal for Science Communication and
to support the charitable activities of the Stephen Hawking Foundation. It could also be part of a subsequent documentary.

François van Schalkwyk and Keenan Carelse,
UFS alumni leading the university’s United
Kingdom Alumni Chapter, have put their voices together to produce and direct the podcast series. Intended to reconnect alumni with the university and their university experience, the podcasts will be featured on the first Monday of every month,
ending in November 2021. Our featured alumni share and reflect on their experiences at the UFS, how it has shaped their lives, and relate why their ongoing association with the UFS is still relevant and important. The podcasts are authentic
conversations – they provide an opportunity for the university to understand and learn about the experiences of its alumni and to celebrate the diversity and touchpoints that unite them.

“Life is too short to abandon what sets you on fire. Find your passion, work hard at it and be great. You will never look back and wish otherwise.” These are the words that postgraduate student Charissa Worthmann lives by, and which have encouraged her to pursue her dream of being a gymnast.
Humble beginnings
After undergoing heart surgery earlier this year, Charissa bounced back stronger than ever. She went on to win five regional gold medals at the Free State Gymnastics Championships in February 2017 and was also crowned Free State Victrix Ludorum. In October 2016 she won a gold medal for her apparatus routine at the South African GymnasticsChampionships.
Charissa, who is currently doing her honours in Biokinetics at the University of the Free State (UFS), said coming from a small town was not always an advantage. “I come from a small town in KwaZulu-Natal where there are not many opportunities. Therefore there was no gymnastics. I found my natural talent, but never had the opportunity to develop it before coming to the UFS.”
Inspired by lecturer
Charissa’s inspiration is Prof Liesl van As, Associate Professor from the Department of Zoology and Entomology. She is also completing her undergraduate Zoology modules to later complete her postgraduate studies in Zoology. “As a student, our lecturers don’t often realise it, but they shape us to aim higher in life.”
According to Charissa, Prof van As is a woman of pure brilliance who has aspects that every woman should aspire to: Beauty, intelligence and a drive to succeed. “I owe a vast majority of my success to her, because even though she may not realise it, her motivational attitude and success in life drove me to succeed in areas of my life.”
