Liezel Rudolph believes opportunities do not fall into your lap, but you cross them when you do what you love, and you do it well.

On more than one occasion, Liezel Rudolph set foot on the SA Agulhas II, travelling the oceans to Marion Island in her quest to research climate change. She focuses her research on reconstructing the past climate of Marion Island. 

As Lecturer in Process Geomorphology in the Department of Geography Rudolph is involved in research on glacial and peri-glacial landforms, trying to understand the links between climate and the processes that shape these landforms.

An interview with her reveals more about this scientist, adventurer, and teacher who sees pursuing one’s research interests and teaching others about it as a dream come true.

 

“Part of being a woman is to know when to be strong and to speak up, and when to be humble and listen.” – Liezel Rudolph

Is there a woman who inspires you, who you would like to celebrate this Women’s Month?

“I would like to celebrate my mother who does everything to the full. She celebrates the little things; she dreams big and she does not fear the future. She values discipline, but nurtures growth and has always encouraged (me) to be the best version of me and not to compare myself to others.”

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

“I don’t like being criticised and I don’t like failing. It has taken me several years to learn that not all criticism is negative and that not all failures are final. And that is OK. I have learned to be easier on myself, and on others when I (or they) don’t meet certain expectations.”

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

“When I was 15 years old, I had no idea what life would be after school – and it scared me. I now know that by following my passion and doing what I am good at, I am doing myself and the world a favour. There is no point in making loads of money if you hate going to work every day. Opportunities do not fall into your lap, but you cross them when you do what you love, and you do it well.”

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

“I would not say that I am a champion woman, yet. But I would like to think that I am a woman who does her job well, and who does ‘woman’ well, too. This means bringing what I have to the table, and not comparing, criticising, or competing with anyone about what else is on the table. I still have to grow a lot in this regard.”

Extending new discoveries in the deep subsurface – UFS paper published in Nature Communications
2015-11-30



Scanning electron microscopy of some of the Eukarya recovered from two different mines. (a) Dochmiotrema sp. (Plathyelminthes), (b) A. hemprichi (Annelida), (c) Mylonchulus brachyurus (Nematoda), (d) Amphiascoides (Arthropoda). Scale bar, 50 µm (a,b), 100 µm (c), 20 µm (d).

Following the discovery of the first Eukarya in the deep subsurface (Nature, 2010) by a research group from the Department of Microbial, Biochemical, and Food Biotechnology at the University of the Free State (UFS) and their international collaborators, intense interest has developed in understanding the diversity of more complex organisms living in these extreme environments.

Prof Gaetan Borgonie from Extreme Life Isyensya, together with a group of UFS researchers, took this research further, resulting in a paper on this research released in Nature Communications – impact factor 11.47.  This paper is an extension of the first reports of more complex life at great depths, and their abilities to survive these harsh conditions.

Ten authors from the UFS contributed with the array of expertise needed to define this discovery. The group was supported by staff from the different mining groups, long-term leading collaborators from the USA and Canada, and the idea specialist driver of the paper, Prof Borganie.

“After a sampling campaign that lasted more than two years, we identified that Platyhelminthes, Rotifera, Annelida and Arthropoda are thriving at 1.4 km depths in fissure water up to 12,000-years old in the South African mines of Driefontein and Kopanang,” said Prof Borgonie, who was appointed as associated researcher in the Department of Microbial, Biochemical, and Food Biotechnology.

This paper really opens a “can of worms” so to speak. According to Prof Esta van Heerden from the Department of Microbial, Biochemical and Food Biotechnology at the UFS they extended to define protozoa and fungi. “However, they are present in low numbers,” she said.

Characterisation of the different species reveals that many are opportunistic organisms. In house-adapted video equipment was used to film inside the fissure for the home of the organisms.

This is the first-known study to demonstrate the in situ distribution of biofilms on fissure rock faces using video documentation. Calculations suggest that food, not dissolved oxygen, is the limiting factor for population growth. The discovery of a group of complex multicellular organisms in the underground has important implications for the search for life on other planets in our solar system.
