Luca van Dijk’s PhD research examined the health and welfare of young calves transported from Ireland to the Netherlands - a major live export route. Her research found that prolonged fasting during transport impacts calves more severely than the journey itself. Crucially, she demonstrated that providing milk replacer during ferry transport significantly improves calf health and wellbeing - findings with direct relevance for Irish and EU policy.

Luca van Dijk, Walsh Scholar Gold Medal WinnerLuca, who grew up in The Netherlands, is a Walsh Scholar registered with Munster Technological University under the supervision of Dr Muireann Conneely (Teagasc) and Dr Gearóid Sayers (MTU).

Before starting her Walsh Scholarship at Teagasc, she completed her Master’s degree at Wageningen University in the Netherlands, where she studied automatic methods to detect disease in veal calves.

Her passion for animal welfare was sparked during hands-on work with cattle in remote Australia. With a clear-eyed view of the challenges in this field, she hopes to continue postdoctoral research in animal welfare after her PhD studies. Jane Kavanagh, Head of Research Development and Walsh Scholars at Teagasc, said:

“The Walsh Scholars Programme supports outstanding postgraduates, registered with our partner universities/HEIs and based at Teagasc, as they undertake applied research that addresses real challenges in the agri-food sector. Through this experience, they develop the skills, insight, and confidence to lead in research, industry, and public service. We’re very proud of this year’s 12 finalists—their talent and dedication are a credit to the programme and to the future of the sector.”

This year, 39 final-year scholars applied for the 2025 Walsh Scholars of the Year competition. Applicants were assessed across five core competencies, submitted written applications, completed science communication training, and - if shortlisted - took part in interviews with external assessors. This rigorous, holistic process ensures the selection of the most outstanding candidate.
