Dr Lisa Rothmann, a plant disease epidemiologist from the University of the Free State (UFS), has been nominated in the TW Kambule-NSTF Award: Emerging Researcher category for this year’s NSTF-South32 Awards.

Dr Lisa Rothmann, a plant disease epidemiologist from the University of the Free State (UFS) who was nominated in the TW Kambule-NSTF Award: Emerging Researcher category for this year’s NSTF-South32 Awards, says that the nomination is a reminder that service through science matters.

“I am humbled by the nomination. For me, it reflects not just individual recognition, but also the shared effort of the team of postgraduate academics, research assistants, partners, and farmers with whom I've had the privilege to work with. It is affirming to see plant pathology and field-based research recognised in this way; it highlights the consistent (hard) work we do to make a meaningful contribution to agriculture and to serve the grain industry and farmers,” says Dr Rothmann. 

She was nominated by Grain South Africa (Grain SA), with whom she has been working closely since 2018 to contribute research that aligns with the organisation’s mission to strengthen the grain sector. They play a key role in supporting sustainable grain production and farmer development. 

Dr Rothmann, who is one of eight UFS researchers and a research team nominated for the NSTF-South32 Awards – also known as the ‘Science Oscars’ – is nominated for her contribution to interdisciplinary, team-based research to develop practical solutions for plant diseases in order to protect crops and empower communities. 

 

Motivation to keep growing

The Senior Lecturer in the Department of Plant Sciences within the Faculty of Natural and Agricultural Sciences (NAS) says that while she is proud of the work she has done, she sees this recognition as a team effort. Says Dr Rothmann: “It motivates me to keep growing as a researcher, rooted in impact and integrity. I’m not a prolific peer-reviewed publisher; my academic record includes 10 journal articles and one book chapter, but I have written around 50 popular articles – often as a solo author, in collaboration with postgraduates and peers.” 

“These pieces translate plant pathology topics such as the Sclerotinia life cycle, disease surveillance, and management into accessible information for producers and the public. To me, this nomination is a symbol that making a meaningful impact doesn't only come from journal impact factors. This nomination has reminded me that building a career in academia is a relay, not a race, and that lasting impact comes from investing in others.”

As a plant disease epidemiologist, she specialises in field pathology – an area of plant pathology that explores how disease epidemics in crops develop, spread, and can be effectively managed within agricultural systems. Their work centres on understanding and managing Sclerotinia diseases in oilseed and protein crops such as canola, soybean, and sunflower, as well as disease surveillance in key grain crops including dry bean, sorghum, and sunflower.

 

New research

After participating in the US-based National Sclerotinia Initiative in 2017, she was inspired to establish a South African Sclerotinia Research Network with the support of Grain SA, creating a platform for researcher collaboration, farmer engagement, and the development of on-farm management strategies. Over time, explains Dr Rothmann, their research has expanded to include cultivar screening, national disease surveys, fungicide registration trials, and the development of disease-assessment tools. More recently, they have embedded sociological surveys into sorghum disease work to better understand farmers’ knowledge and needs, ensuring that research remains practical and co-created with producers.

According to Dr Rothmann, they have been privileged to work in a space that supports producers and protects crops through applied plant disease management strategies. While high-value crops often attract attention due to export markets, the grain that feed the nation forms the backbone of food security. As part of their new research, Dr Rothman and the research team are currently contributing to the Sorghum Cluster Initiative's pre-breeding programme, where they have screened 160 accessions for diseases to support future cultivar development. 

They are also going to explore how both emerging and commercial farmers will adopt these new cultivars. She is actively seeking collaborators in sociology/psychology or similar fields to better understand farmers’ decision-making. They are developing a plant disease dashboard to map disease occurrences across South Africa – an effort aligned with the Plant Health (Phytosanitary) Act 35 of 2024 to help guide appropriate disease risk categorisation. In the long term, concludes Dr Rothmann, they hope to establish a diagnostic hub for central South Africa in partnership with Agricultural Research Council-Grain Crops to strengthen local disease identification and support producers in real time.

UFS researcher fills void in South African policing history

Currently a Postdoctoral fellow in the International
Studies Group, Dr Cornelis Muller’s PhD thesis explores
late nineteenth century South African policing on the
Witwatersrand.

“I used policing on the Witwatersrand as a lens through which to examine aspects relating to state formation within the South African Republic.”

This is how Dr Cornelis Muller, a postdoctoral fellow in the International Studies Group at the University of the Free State (UFS), described his PhD thesis called Policing the Witwatersrand: A history of the South African Republic Police, 1886-1899. The thesis fills an empirical void in the history of settler colonial policing in South Africa.

His research was also featured in the South African Historical Journal, which is published by Routledge. Dr Muller received his PhD from the UFS during the 2016 Winter Graduation ceremonies. He received a scholarship from the university to conduct his three-year research.

Relationship between police and state examined

The study presents itself as an institutional biography in which the relationship between the South African Republic Police (known as the Zarps), the state, and broader society are examined. The period under investigation was a time when political, economic, and social complexities on the Witwatersrand created tension between South Africa and Great Britain.

An important theme throughout the thesis is the relationship between the police, the mining industry, and the so-called Uitlander community. Crime was also an important contributing factor to the complex relationship that developed between the Zarps and the policed in Johannesburg’s formative years.

“Johannesburg was a town under siege by a variety of crimes which ranged from vagrancy, drunkenness, gambling, and prostitution to robbery, murder, and assault,” said Dr Muller.

Archives in South Africa and Great Britain consulted
“My thesis follows a chronological approach in which various themes accounting for the development of the police on the Witwatersrand are highlighted.” Framed within the bureaucratic and administrative functioning of the Zarps, he examined aspects relating to crime, crisis, and conflict between the police and society. The thesis also details the relationship between the police and Johannesburg’s black community.

As with any historical research, it comprised internal and external source criticism and content analyses of a wide range of archival records.

Dr Muller had the opportunity to visit several archives and libraries in South Africa and Great Britain. “Some of the more important archival collections were assessed at the National Archives in Pretoria.” These included the Archive of the State Attorney and the Archive of the Magisterial District of Johannesburg.

“My study thus adds to scholarship that seeks to provide a more nuanced understanding of the South African Republic’s administrative functioning and internal politics in the late nineteenth century,” concluded Dr Muller.
