Leadership
The people responsible for the work.
Northbridge is led by people who stay with a problem from the question through to the system that has to carry the answer.

Managing Director
Oluwafemi O. BalogunMBBS, MPH
Oluwafemi O. Balogun leads Northbridge & Company. He is a physician and epidemiologist whose work sits with health systems, evidence, and the information institutions use to manage programmes.
He trained in medicine at the University of Ilorin and holds a Master of Public Health in Epidemiology and Biostatistics from Boston University. His practice includes health-systems advisory with the World Bank; disease surveillance with the World Health Organization in Nigeria and the Massachusetts Department of Public Health; and biostatistics and clinical research at Massachusetts General Hospital and Harvard Medical School. He has published on travel medicine, viral haemorrhagic fever, tuberculosis, hepatology and neurocritical care, and is an Associate Editor at Frontiers in Digital Health.
At the firm he is responsible for how an engagement is framed: the decision to be made, the evidence it requires, and the systems through which the work is carried out.
- Health systems and primary care
- Epidemiology, surveillance and biostatistics
- Digital health and decision systems

Director, Evidence
Amaka Eze
Amaka leads the firm’s work on measurement, reviews and the use of results. She helps an institution decide what should be measured, which source can support a decision, and how findings enter management rather than remaining in a report.

Director, Institutions
Yusuf Danjuma
Yusuf works with ministries, agencies and programme teams on mandates, governance and operating routines. The focus is the institution that has to carry a decision after the advice has been given.

Director, Digital Systems
Ngozi Okeke
Ngozi leads the specification and introduction of information systems that fit the way a team already works. The work covers data platforms, programme tools and the conditions under which a system has to be maintained.

Director, Operations and Management
Moyinloun Balogun
Moyinloun Balogun is responsible for the firm’s operations and for the management of delivery: the people, the routines, and the arrangements through which the work is carried out.
She has worked in administration and operations for more than eight years, including terminal operations at A.P. Moller–Maersk in Lagos, and in technology, enterprise and non-profit settings. That work has covered staff administration, records, coordination for senior management, and the routines that keep an organisation in order.
- Operations and delivery routines
- People, records and administration
