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.

Names are not enough: a molecular-based information system is the answer

South Africa is the second-largest exporter of citrus in the world, producing 60% of all citrus grown in the Southern Hemisphere. It exports more than 70 % of its citrus crop to the European Union and USA. Not being able to manage fungal pathogens effectively can have a serious impact on the global trade in not only citrus but also other food and fibre crops, such as bananas, coffee, and cacao.
The Department of Plant Sciences at the University of the Free State (UFS) hosted a public lecture by Prof Pedro W. Crous entitled “Fungal Pathogens Impact Trade in Food and Fibre: The Need to Move Beyond Linnaeus” on the Bloemfontein Campus.
Prof Crous is Director of the world’s largest fungal Biological Resource Centre, the Centraalbureau voor Schimmelcultures (CBS), in the Netherlands. He is also one of the top mycologists in the world.
Since the topic of his lecture was very pertinent to food security and food safety worldwide, it was co-hosted by the Collaborative Consortium for Broadening the Food Base, a multi-institutional research programme managed by Prof Wijnand Swart in the Department of Plant Sciences.
Reconsider the manner in which pathogens are identified
Prof Crous stressed that, because international trade in products from agricultural crops will expand, the introduction of fungal pathogens to new regions will increase. “There is therefore an urgent need to reconsider the manner in which these pathogens are identified and treated,” he said.
According to Prof Crous, the older Linnaean system for naming living organisms cannot deal with future trade-related challenges involving pests and pathogens. A system, able to identify fungi based on their DNA and genetic coding, will equip scientists with the knowledge to know what they are dealing with, and whether it is a friendly or harmful fungus.

Embrace the molecular-based information system
Prof Crous said that, as a consequence, scientists must embrace new technologies, such as the molecular-based information system for fungi, in order to provide the required knowledge.
He presented this very exciting system which will govern the manner in which fungal pathogens linked to world trade are described. This system ensures that people from different countries will know with which pathogen they are dealing. Further, it will assist with the management of pathogens, ensuring that harmful pathogens do not spread from one country to another.
More about Prof Pedro Crous
Prof Crous is an Affiliated Professor at six international universities, including the UFS, where he is associated with the Department of Plant Sciences. He has initiated several major activities to facilitate global research on fungal biodiversity, and has published more than 600 scientific papers, many in high impact journals, and authored or edited more than 20 books.
