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.

Twee broers lewer intreerede
2004-06-10

‘n Unieke geleentheid sal homself môre, 9 Junie 2004, voordoen wanneer twee broers - proff Francois en Janse Tolmie - tydens dieselfde geleentheid hul intreeredes aan die Universiteit van die Vrystaat (UV) sal lewer.

Prof Francois Tolmie is verbonde aan die UV se Departement Nuwe Testament en die onderwerp van sy lesing is Die impak van die metodologie op die verstaan van die Nuwe Testament. Prof Janse Tolmie, sy jonger broer, is verbonde aan die UV se Departement Rekenaarwetenskap en Informatika en die onderwerp van sy lesing is Die rol van inligtingstegnologie in kennisbestuur.

Hoewel die studievelde vér verwyderd staan, klop die twee broers se missies wat betref die terugploeg van die verworwe vakkennis ten bate van die gemeenskap. Prof Francois Tolmie is nóú betrokke by dowes en Prof Janse Tolmie tap weer kunsmatige intelligensie ten bate van die mediese wetenskap en geestesgesondheid.

Prof Francois Tolmie verwerf die grade BA, BA Honneurs (Grieks), MA (Grieks), B Th en M Th almal cum laude aan die UV. In 1992 verwerf hy 'n D Th (Nuwe Testament) en in 2004 'n Ph D (Grieks) aan dieselfde universiteit. Na sy militêre diens as kapelaan in Walvisbaai aanvaar hy 'n beroep na die NG-gemeente Walvisbaai. Hy begin sy akademiese loopbaan op 1 April 1990 as senior lektor in die Departement Nuwe Testament en word in 1999 tot medeprofessor en in 2003 tot professor bevorder.

Sy navorsingspesialiteit is die Johannesevangelie en die Brief aan die Galasiërs. Hy is tesourier van die Nuwe Testamentiese Werksgemeenskap van Suid-Afrika, lid van die Society of Biblical Literature en die Studiorum Novi Testamenti Societas, redakteur van Acta Theologica en assistent-redakteur van Neotestamentica. Hy het reeds 34 artikels in geakkrediteerde tydskrifte gepubliseer, asook drie populêr-wetenskaplike boeke en talle bydraes in populêr-wetenskaplike boeke. Hy het twee akademiese boeke in die buiteland gepubliseer - onderskeidelik in Nederland en in die VSA. Later vanjaar verskyn 'n derde akademiese boek in Duitsland. Hy is ook een van die vertalers van die Afrikaanse Bybel vir Dowes.

Prof Janse Tolmie verwerf die grade B Sc, B Sc (Hons) en M Sc (Cum Laude) in Rekenaarwetenskap aan die UV.

Hy is vanaf 1989 betrokke by die UV en was ook ’n dosent aan die Militêre Akademie in Saldanhabaai in 1990/91 en het klas gegee by DePaul Universiteit in Chicago in 2002.

In 1992 is hy vir ses maande gesekondeer na ’n patologiese firma, Van Drimmelen en Vennote, in Johannesburg vir die ontwikkeling van kennisgebaseerde sagteware. Met hierdie projek word hy een van slegs ’n handjievol navorsers in die wêreld wat daarin kon slaag om ’n mediese kundigheidstelsel te ontwikkel wat werklik gebruik word.

Hy verwerf sy Ph D in 1994 en in 1994/95 doen hy navorsing aan die Besigheidskool van Carleton Universiteit in Ottawa, Kanada. Hy word in 1997 bevorder tot mede-professor en in 2003 tot volprofessor. Vanaf 2003 tree hy op as departementele voorsitter van die UV se Departement Rekenaarwetenskap en Informatika.

Hy het meer as 30 publikasies al die lig laat sien, insluitend verskeie internasionale kongresbydraes en artikels in geakkrediteerde joernale. Hy was ook vir 2 siklusse geëvalueer by die NRF. Sy portfolio sluit in die ontwikkeling van sagteware of prototipes vir groot maatskappye soos Van Drimmelen en Vennote en Bayer Diagnostics (VSA). Sy privaatbesigheid fokus op die ontwikkeling van nismarksagteware vir tersiêre instellings. Die sagteware word tans gebruik deur afdelings aan verskeie universiteite in Suid-Afrika.

Die geleentheid vind om 19:00 in die CR Swart-ouditorium op die kampus plaas.
