Making connections through One Health Edgar Onyango’s interest in health brings together his background in biomedical engineering and communications. His postgraduate studies have since brought these areas together, with a focus on One Health, antimicrobial resistance – the ability of bacteria and other organisms to resist drug treatment – and the importance of communicating health information in accessible ways.A Mastercard Foundation Scholar from Kenya, Edgar is graduating this year with a Postgraduate Diploma in One Health. Alongside his studies, he has worked to build connections between fellow scholars and online students, contributing to student life and the wider University community, experiences which recently earned him the Sir William Darling Memorial Prize.A wider connectionThe Sir William Darling Memorial Prize, awarded by the University of Edinburgh’s Principal Professor Sir Peter Mathieson, recognises students who, in the opinion of Professor Mathieson, have made significant contributions to enhancing the University's reputation through their outstanding conduct. For Edgar, building those connections became particularly important as an online student.His contribution to the University community extended beyond his own cohort, including through his involvement in community-building activities among Mastercard Foundation Scholars and opportunities for students from different backgrounds to meet and share experiences. He applied for funding to create opportunities for online students to connect with one another and organised in-person meet-ups for University of Edinburgh Mastercard Foundation Scholars in Kenya."It was really special to be recognised in that way, particularly because so much of my experience at Edinburgh has been about connection."Bridging health and impactEdgar’s interest in One Health grew from a desire to bring together his academic knowledge of biomedical engineering and health-related communications to make a difference to healthcare in Kenya."I was motivated by a desire to use health communication to make complex health information more accessible and understandable to people."For him, effective communication is an important part of addressing complex health challenges.His approach was influenced in part by the Covid-19 pandemic and the way simple, accessible messages around handwashing helped people understand the role they could play in protecting health."It showed me the importance of communicating health information in a way that people can understand and relate to."One Health offered an opportunity to explore the connections between different areas of health, while developing the knowledge and skills to communicate those issues more effectively.Finding a community onlineAlthough Edgar studied remotely from Kenya, he developed a strong link with the School."I felt a very warm connection to the School, even as an online student."He particularly valued the support of student advisers and teaching staff, who he found consistently willing to help students get the most from their studies."The heart of the teaching team came through in their desire for students to truly understand the subject matter, rather than just pass."One experience in particular stayed with him."An academic remembered something I had said during the welcome introductions and asked me to expand on it several months later."For Edgar, this demonstrates the level of engagement he experienced throughout the programme."It showed me that they were really listening. There was always a willingness and openness to share, and I knew the staff were there for me."He found this reflected in the prompt responses to questions, engaged discussions and collaborative approach of the teaching team.Bringing students togetherEdgar’s experience as an online student also inspired him to create opportunities for others to connect.Through his work with fellow Mastercard Foundation Scholars, he has brought together students who might otherwise have experienced their studies separately.His recent visit to Edinburgh provided another opportunity to strengthen those connections, this time with students on campus.Looking aheadAs Edgar graduates with his Postgraduate Diploma in One Health, he hopes to continue bringing together his interests in health, communication and impact.His focus on accessible health communication remains important to him, with Kenya providing an important context for his work.His time at Edinburgh has also reinforced the value of collaboration and connection."I’ve learned that studying is not just about the qualification. It’s also about the people you meet, the conversations you have and what you can do with what you learn."From studying online in Kenya to being recognised in the University’s McEwan Hall at graduation, Edgar’s Edinburgh journey has connected academic study with a wider ambition: to use knowledge, communication and community to make a difference in health.
