Prof Carlien Pohl-Albertyn, a successful scientist, is living her dream job, as she gets to pursue her passion for microbiology; a career she wanted to pursue ever since Grade 10.

Prof Carlien Pohl-Albertyn, a professor of Microbiology in the Department of Microbiology and Biochemistry, is the holder of the SARChI Chair in Pathogenic Yeasts at the University of the Free State (UFS). She is leading the Pathogenic Yeast Research Group, studying pathogenic yeast infections and necessary treatment options and bringing hope to many immunosuppressed patients battling HIV/Aids, cancer, diabetics, and other diseases. She also recently co-authored an article on the incidence of fungal infections in COVID-19 patients. 

“This is my dream job, as I get to pursue my passion for microbiology,” says Prof Pohl-Albertyn, who already knew as early as Grade 10 that she wanted to become a microbiologist. “I have always been fascinated by the natural world and have known since childhood that I would become a scientist,” she says. 

An interview with Prof Pohl-Albertyn reveals more about the persons who inspired her, her view on the development of women, and how she approaches her work. 

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

“The first woman who instilled a love for the biological sciences in me was Miss Steyn, my high school Biology teacher. She had a passion for teaching that inspired me to become a microbiologist.”

Prof Pohl-Albertyn, however, states that there were many other women who constantly inspired her to be a better person. 

“My mother inspires me to take responsibility for my choices; my mother-in-law inspires me to be kinder to others; and my best friends’ mothers inspire me to persevere, even when things are difficult.”

“I am also inspired by my female friends, Ezelle van den Heever, who has shown me that there is always a plan to be made to solve a problem; Trudi O’Neill, who manages to balance high-level research, teaching, and administration with her home life; Alicia Sherriff, from whom I am learning to be more emotionally intelligent; and Janine Allen, who has expanded my horizons and regularly shows me how to look at the world in a completely different way.”

What is your response to current challenges faced by women and available platforms for women development?

“Coming from a fairly male-dominated cultural background, I realise that I have been very privileged to not experience challenges just because I am a woman. I have been able to study and work in a field that values women and men equally and have chosen a very capable and extremely supportive husband, who sees me as an equal.”

She, however, realises that this is not the case for many women, and understands that there are women who were not able to follow their dreams and make their own life choices.

Prof Pohl-Albertyn believes that any opportunity for women to overcome challenges should be encouraged, as a society will ultimately be better if everyone is able to fulfil their greatest potential.

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

This successful scientist, spouse, mother of two sons, daughter, friend, and mentor to many, says that she will advise her 15-year-old self to do everything the way that she has been doing it. “I do not regret anything and would not change my life in any way,” she says. 

What would you say makes you a woman of quality, impact, and care?

“I am a person of quality because of my integrity, work ethic, and commitment to my responsibilities – something that is easy if you enjoy what you do every day.”

“I am a person of impact because of the influence I have on my colleagues, who I always treat with respect, and my students, who I teach to the best of my abilities, and which I hope will serve them well in their careers.”

“I am a person of care because I value the contributions of my colleagues and students to my own growth and development,” remarks Prof Pohl-Albertyn.

Her advice to farmers is that they should make sure they are aware of the total cost (investment and operating costs) of an irrigation system. In most cases the investment cost is low, but the operating cost over the lifetime of the system is high.

“It is very important to have a look at the total cost and to install the most economic system,” says Marcill Venter, lecturer at the University of the Free State (UFS), who has done research on the economic sustainability of water-pipe systems.

Irrigation systems important components for farming
This research comes at a time when many farmers are relying on their irrigation systems due to persistent drought and low rainfall during 2016. South Africa has also experienced an abnormal increase in electricity tariffs in recent years. Due to tariff increases which threaten the future profitability of irrigation producers, the Water Research Commission (WRC) has launched and financed a project on the sustainable management of irrigation farming systems. “I had the opportunity to work on the project as a researcher,” says Venter.

The heart of every irrigation system is the water pipes that bring life to crops and livestock, and this is what Venter’s research is about. “Water pipes are part of the whole design of irrigation systems. The design of the system impact certain factors which determine the investment and operating costs,” she says.

Mathematical system to help farmers
Venter and Professor Bennie Grové, also from the Department of Agricultural Economics at the UFS, designed the Soil Water Irrigation Planning and Energy Management (SWIP-E) programming model as part of the WRC’s project, as well as for her master’s degree. “The model determines irrigation pump hours through a daily groundwater budget, while also taking into account the time-of-use electricity tariff structure and change in kilowatt requirements arising from the main-line design,” says Venter. The model is a non-linear programming model programmed in General Algebraic Modeling System (GAMS).

Design of irrigation system important for sustainability

The main outcome of the study is that the time-of-use electricity tariff structure (Ruraflex) is always more profitable than the flat-rate structure (Landrate). The interaction between the management and design of a system is crucial, as it determines the investment and operating costs. Irrigation designers should take the investment and operating cost of a system into account during the design process. The standards set by the South African Irrigation Institute (SAII) should also be controlled and revised.

Water-pipe thickness plays major role in cost cuts
There is interaction between water-pipe thickness, investment and operating costs. When thinner water pipes are installed, it increases the friction in the system as well as the kilowatt usage. A high kilowatt increases the operating cost, but the use of thinner water pipes lowers the investment cost. Thicker water pipes therefore lower the friction and the kilowatt requirements, which leads to lower operating costs, but thicker pipes have a higher investment cost. “It is thus crucial to look at the total cost (operating and investment cost) when investing in a new system. Farmers should invest in the system with the lowest total cost,” says Venter.
