TIMB Members

The previous TIMB monitored the situation over a period of three years (November 2016 – December 2019), in the light of progress towards polio eradication. Its role was to independently assess the GPEI’s policy and plans to transition and sustain those polio assets and resources that have played a major dual role in underpinning wider immunisation and other essential health programmes. The TIMB members played an invaluable part in meetings and in the production of three major reports that helped to shape the polio transition process.

TIMB Reports – GPEI

With the adoption by the 71st World Health Assembly of a 5-year strategic plan for polio transition, responsibility for leading planning and implementation passed to the World Health Organization. Necessary organisational changes followed and included a new TIMB to be smaller and more closely aligned with the IMB.

Strategic Action Plan on Polio Transition – WHA 71

On the basis of the new arrangements three TIMB members have been appointed to serve under the chairmanship of Sir Liam Donaldson who will also continue to chair the IMB.


Sheila Leatherman, CBE, Hon RCP is a Professor of Global Health Policy at the Gillings School of Public Health of the University of North Carolina. Her professional experience stretches across the breadth of health care management, public health and health policy with expertise in quality of care, performance improvement in the health sector, and health systems reforms. She has worked with over 50 countries globally across North America, Europe, Africa, Asia and Latin America. Most of her research and policy analysis has been on developing methods to assess health system performance and advising on how to improve quality of care in countries throughout the world.

She was elected to the U.S. National Academy of Sciences in 2002 as a member of the Institute of Medicine. In 2007 she was awarded the honour of Commander of the British Empire (CBE) by Queen Elizabeth for her work in the National Health Service for over a decade and was appointed an Honorary fellow of the Royal College of Physicians in The UK in 2008. In 2019, she received the Presidential Distinction Award of the International Society for Quality in recognition of her work in low- and medium-income countries.

Currently, as a Lead advisor to the World Health Organization she develops the academic and technical foundations for WHO support of Member States in the development of national health care quality agendas to improve health care services and outcomes globally. Her current research focuses on improving care in fragile states, humanitarian crises and conflict zones.

Senjuti Saha is a Bangladeshi-Canadian microbiologist working at the intersection of Clinical Microbiology and Global Health as a Scientist at the Child Health Research Foundation in Bangladesh. Her work is grounded in advancing the cause of health and research equity, based on her vision that everyone across the world should have equal access to the practice and benefits of science. The focus of her work is on paediatric preventable infectious diseases, with the goals of: (1) using state-of-the-art technology like on-site metagenomics to identify aetiologies that elude standard laboratory testing in low- and middle-income countries and (2) understanding the indirect impacts of interventions like vaccines on the overall health system. She advocates for equal access to scholarly literature and science education. The team’s mission at the Child Health Research Foundation in Bangladesh is to break free of the vicious cycle of limited resources that lead to lack of data required for evidence-based policy decisions. This in turn leads back to limited resources; instead, the commitment is to build virtuous cycles of data-generation, that are sustainable and cost-effective.
