Saïd Business School and Green Templeton College Scholarship

Ko Ozaki is a DPhil student in Management at Green Templeton College, beginning his studies in 2025. Originally from Japan, Ko spent over a decade as a government official before coming to Oxford, holding roles across trade policy, international standards (ISO), and cyber security. Through this work, he became increasingly aware of how deeply government policies and regulations shape the operations and strategies of private firms. His experiences revealed that international businesses must learn to navigate complex relationships with governments in order to survive. This realisation inspired his journey to Oxford. During Ko’s time working in the Japanese government, he became intrigued by the issue of how firms can effectively manage political risks and respond to geopolitical tensions, challenges that are becoming ever more significant in today’s world. He completed his undergraduate studies at the University of Tokyo and his master’s degree at Stanford University.

Michelle completed a Bachelor of Health Sciences at McMaster University, an MSc in Medicine, Health and Public Policy at King’s College London, and an MPhil in Medical Anthropology at the University of Oxford.

Her DPhil research explores how AI-enabled innovations can be most effectively and equitably integrated into complex healthcare systems like the NHS. Using AI diagnostic tools in skin cancer care as a case study, her work examines how clinicians, patients, and organisations experience, adapt, and negotiate the use of these technologies in practice. Drawing on implementation science and sociotechnical systems thinking. She is particularly interested in how innovation can be introduced in ways that reduce-rather than reinforce-existing inequities in access, representation, and outcomes.

Sir David Weatherall Scholarship

Cleo’s research focuses on how genes are regulated, specifically exploring enhancer biology. Her project examines whether the orientation of enhancers plays a role in gene activation at a model locus. She is also studying the different components of super-enhancers and their various roles in gene regulation. Broadly, her field aims to reveal the precise mechanisms by which genes are regulated in healthy cells, and how these processes can go wrong in disease.

Clarendon Scholarship

A California native, Malia completed her undergraduate studies in Biology and Spanish at the University of California, Los Angeles (UCLA) in 2019. She sparked her interest in global health after interning for a summer in Spain with ISGlobal, a research group focused on malaria vaccines. Malia went on to earn a Master of Science in Global Health and Population from the Harvard TH Chan School of Public Health. During her first semester, the onset of the COVID-19 pandemic provided opportunities to contribute to several ongoing research projects, through which she developed core research skills.

After her Masters, she spent two years in Washington D.C., working as a Technical Advisor with Population Services international (PSI) in their Malaria Department. Before starting her DPhil, she lived in South America for a year as a Fulbright Scholar researching pathways for routine surveillance data management for Chagas disease.

Malia is currently in the second year of her DPhil and is based at the Mahidol Oxford Tropical Medicine Research Unit (MORU) in Bangkok, Thailand. Her DPhil work focuses on measuring the impact of interventions for the control and elimination of tropical infectious diseases, including malaria, dengue and Chagas. In the future, Malia hopes to return to the NGO sector and is open to pursuing policy work, as she believes this offers the most direct opportunity to see the day-to-day impact of her efforts.
