Richard Dooso and Geoffrey Beyihayo’s time with us at CTLGH was a blend of scientific exploration, collaboration and cultural exchange.
The visiting scientists’ work reflects the shared goal of advancing livestock genetics to address global challenges in agriculture.
Richard Dooso, a PhD Graduate Fellow at the International Livestock Research Institute (ILRI), focused on mapping genomic regions associated with resilience in crossbred dairy cattle, leveraging advanced genomic tools to support climate adaptation in sub-Saharan Africa.
Meanwhile, Geoffrey Beyihayo worked on refining the Indigenous Chicken Breeding Program (ICBP) at Gulu University in Uganda, introducing robust genetic evaluation techniques to enhance breeding strategies for local chicken populations.
Richard Dooso: Mapping Resilience in Dairy Cattle
Mr Dooso collaborated with Dr Getinet Tarekegn and Professor Mike Coffey to map genomic regions associated with resilience in dairy cattle as part of the African Asian Dairy Genetic Gains (AADGG) project, funded by the Bill and Melinda Gates Foundation (BMGF).
His work centred on identifying genetic markers and specific regions of DNA that influence resilience in crossbred dairy cows in sub-Saharan Africa. To explore the genomic architecture underlying these traits, Richard used a method known as advanced single-step genome-wide association studies (ssGWAS).
This work is key for developing a resilience index, which can guide the selection of climate-resilient dairy cattle for low- and middle-income countries (LMICs).
While significant progress was made during his visit, Mr Dooso’s work remains ongoing. “My area of interest aligns perfectly with CTLGH’s work and what they stand for, and I envision plenty of opportunities for more collaborations in the future beyond this visit.”, he added.
Geoffrey Beyihayo: Advancing Indigenous Chicken Breeding
Mr Beyihayo, from Gulu University in Uganda, partnered with Dr Kellie Watson and Dr Oswald Matika, among other CTLGH scientists to refine the Indigenous Chicken Breeding Programme (ICBP) at his home institution.
Together, the team reviewed and restructured the programme, incorporating tools for tracking pedigree and estimating breeding values. These enhancements aim to boost genetic progress and strengthen the breeding programme’s infrastructure for maintaining robust records.
Geoffrey expressed a strong commitment to maintaining his collaboration with CTLGH, noting the need for sustained efforts to fully realise the potential of the ICBP. “After this visit, I am a proud member of CTLGH” – he says – “It is important that we keep in touch for collaborative research, funding and to share new advances in the field of poultry genetics.”
Personal reflections
Both PhD candidates both highlighted the exceptional support, resources, and welcoming environment they experienced during their time at CTLGH.
Richard praised the Centre’s collaborative and innovation-driven atmosphere, noting, “The scientists I was working with are highly skilled and deeply passionate about their work, which created an inspiring atmosphere.” He also expressed gratitude for personalised mentorship, adding, “Dr Tarekegn’s follow-up calls to ensure my codes were running smoothly were incredibly reassuring, and Prof. Coffey’s open-door policy, despite his busy schedule, made consultations so easy.”
Similarly, Geoffrey valued the personal experience shared and technical guidance he received, saying, “Dr Watson, Dr Kebede, and Dr Matika helped me gain access to literature, computer programmes, and software.” He also benefited from informative presentations at the Roslin Institute.
Both scientists found Edinburgh’s vibrant culture and the warm hospitality of the CTLGH community unforgettable, especially thanking Jen Meikle’s thoughtful gestures. Both researchers enjoyed exploring Edinburgh, with Geoffrey Beyihayo adding, “Touring museums, Edinburgh city, and Edinburgh Castle spiced up my stay at CTLGH.”
Broader Impact of the Visits
Both visiting scientists emphasised the importance of this initiative in fostering scientific growth and global collaboration.
“These opportunities empower early-career scientists to develop their skills and bring back valuable knowledge to their home institutions” – Richard notes. Geoffrey reiterated the irreplaceable value of in-person mentorship, which accelerates learning and builds lasting professional relationships.
We look forward to continuing our collaboration with them and supporting their work in livestock genetics and health.
