Each year, the Nuffield Department of Medicine awards prizes to its graduate research students for various achievements, including success in terms of discoveries and published work, significant achievements in establishing infrastructure, success in strongly collaborative projects, and involvement in public engagement and other departmental activities.
Ngo Thi Hoa: Zoonotic diseases and community health
Ngo Thi Hoa leads research on zoonotic pathogens and antimicrobial resistance, focusing on Streptococcus suis and farm-origin resistance in Vietnam. Her work highlights how antibiotic use in livestock, including colistin, contributes to resistance in humans. She advocates for sustainable One Health platforms to generate data, reduce antimicrobial use, and prevent future pandemics.
Francis Ndungu: Decoding natural immunity to malaria
Francis Ndungu studies malaria immunity using controlled human infection models to understand protective mechanisms in highly exposed populations. His research supports vaccine development and optimisation, including RTS,S and R21. By reducing malaria burden, especially among children and pregnant women, these tools also have the potential to accelerate economic development in endemic countries.
Charles Sande: Paediatric infection and immunity
Charles Sande investigates why some children in sub‑Saharan Africa survive infections while others do not. Using proteomics, transcriptomics, metagenomics and clinical data, his work identified immune differences linked to mortality. A recent multi-country study highlighted IL10 as a key marker of high-risk children, supporting more targeted care and personalised interventions.
Dorcas Kamuya: Voices of health research ethics in Kenya
Dorcas Kamuya leads research on the ethics of emerging technologies, collaborative science, and pandemic response. Her work explores ethical frameworks for biobanking and cell line generation in Africa, addressing social acceptability, cultural norms, and equity. She advocates for proactive, context-specific ethics to ensure research is inclusive, trustworthy, and impactful in African settings.
Wirichada Pan ngum: Modeling for maximum impact on health research
Wirichada Pan ngum leads a modelling group using statistical and mathematical approaches to address regional health challenges. Her work on hepatitis C informed Thailand’s treatment and screening policies. Current priorities include integrating AI into modelling and addressing climate change and mental health. Her team also focuses on local capacity building for sustainable impact.
Emelda Okiro: Transforming birth and death registration
Emelda Okiro researches how to strengthen birth and death registration systems in Kenya by identifying barriers in both the health system and communities. Her work uses surveillance data, interviews and focus groups to co-design context-specific interventions, aiming to improve real-time data, accountability, and ultimately equitable access to services and policy planning.
Anthony Etyang: Unmasking hypertension - the silent killer
Anthony studies hypertension in Kenya and The Gambia, focusing on improving diagnosis, treatment, and blood pressure control. His research addresses low awareness and treatment gaps, aiming to prevent severe outcomes like stroke and heart failure. With over 25% of adults affected, his work targets a major cause of premature death in Africa.
Kevin Marsh: Africa in partnership with Oxford
Kevin leads the Africa Oxford Initiative (AfOx), promoting equitable research, education, and innovation partnerships between African researchers and the University of Oxford. His work focuses on strengthening collaborations, expanding graduate opportunities, and supporting Africa’s knowledge-driven future. Key challenges include defining equity in partnerships and adapting to shifting global research funding landscapes.
James Watson: Data driven definitions of severe malaria
James Watson studies severe malaria in African children, focusing on improving diagnostic accuracy. By analysing clinical data, he aims to distinguish malaria-related severe illness from other infections and estimate true mortality more reliably. His work supports faster diagnosis and treatment, ultimately reducing preventable child deaths in low-resource settings.
Sonia Lewycka: One Health interventions to combat antimicrobial resistance
Antimicrobial resistance can be viewed through a One Health lens across humans, animals and the environment. Focussing on primary care, tests offered at point-of-care in Vietnam to curb antibiotic overuse yielded promising but nuanced results. The Just Transition initiative, examining justice implications of AMR policies globally, aims to align efforts with climate change mitigations for mutual benefits.
Sassy Molyneux: Strengthening health and research systems
Health systems in LMICs face daily stresses such as resource shortages and policy changes, alongside periodic shocks such as epidemics. Enhancing resilience combined with research ethics ensures high-quality research responsive to local communities. Minimising moral distress among frontline staff in international research is crucial for sustaining quality healthcare and advancing science amid challenging conditions.
Proochista Ariana: Building capacity for global health impact
The intersection between international developments and health is complex and multidimensional. Development initiatives, such as building roads, can enhance access to healthcare, education and markets, yet may also increase risks such as accidents and disease transmission. In Liberia, we investigate factors contributing to maternal and neonatal mortality through policy analysis and community perspectives. Our Master’s in International Health and Tropical Medicine aims to foster effective solutions and capacity building in global health leadership.
Jacob McKnight: Preparing Kenya’s health system for extreme weather
In both high- and low-income countries, health systems need to be ready for extreme weather. While sustainability efforts are underway, health systems must cope with events like floods and droughts, which increase healthcare demand and disrupt services. The NEWRISK project in Kenya addresses these challenges, emphasizing resilience and insurance strategies to maintain healthcare access during crises, amid climate change's broad impacts on health systems.
Philippe Guérin: Enabling data reuse to combat infectious diseases
IDDO is a data platform that facilitates the integration and analysis of individual patient data from diverse studies, uncovering new insights otherwise inaccessible. Through meticulous curation and merging of data, IDDO unearth crucial evidence, such as the impact of malaria treatment on malnourished children, a group usually excluded from trials. This comprehensive approach not only informs better treatment strategies but also identifies gaps in current knowledge, guiding future research directions and potentially transforming healthcare guidelines worldwide.
Susanna Dunachie: Vaccines for vulnerable populations
Focussing on vaccines for vulnerable populations, the Tropical Immunology Research Group study immune responses in healthy individuals to understand how to protect those with frail immune systems, such as the elderly and diabetics, from bacterial infections like E. coli and Klebsiella. Key goals include identifying immune markers of protection and designing vaccines to prevent deaths in low- and middle-income countries. Addressing antimicrobial resistance is urgent to prevent untreatable future infections.
