About Us


Meet the CEDARS Team!


CEDARS is an initiative of the International Health and Development (IHD) Division of ICF. We aim to be a learning and practice network focused on advancing sustainability and impact in development practice. We aim to focus our work on three strongly overlapping areas of interest:

track 1 Sustainability in community health and health systems - Improving sustainability design, implementation and evaluation in community health
track 2 Global challenges to sustainable health and human development - From food security, to building community resilience and adaptive capacity, to climate change
track 3 Applying complex systems analysis to our understanding of sustainable human development - Improving evaluation and study designs on the functioning of complex adaptive systems (community and civil society, health systems, donor systems) and their impact on sustainable human development.

We bring together partners, consultants and practitioners from a number of organizations. This community of practice is at the heart of our work. Click here to learn more about the CEDARS Community of Practice. The ICF team members are introduced below - don't hesitate to contact any of us:

Name Biography

Eric Sarriot, MD, PhD

If CEDARS had a director,
he might be it.

Eric likes to say that he "used to be a doctor", having graduated from the Paris VI Necker School of Medicine in 1989. After some balancing of his time between clinical practice, surveillance of infectious diseases and communications projects, he trained in Tropical Medicine then got a Masters in Public Health and Social Urban Development. That took him to do participatory qualitative research and to work for World Vision in Mauritania. Reportedly this is when he started banging his head against the walls about the sustainability question. He obtained his PhD from Johns Hopkins while working with the Child Survival Technical Support project and the CORE Group to conduct a research which led to the development of the Sustainability Framework. He rejoined ICF Macro while living in Palestine/Israel. He is currently the Community Health and Civil Society Engagement team lead on USAID's Maternal and Child Survival Program.

Navigating between practice, technical assistance, evaluation and implementation research on concepts as charged as sustainability (which he claims in indissociable from the focus on "scale up"), he continues to be challenged by the complexity of sustainable social progress and the many ways in which we try or fail to address it.

Quote: "Is it sustainable" is a question for theologians, not development professionals. "How sustainable is it?" is the question we should care about, at least when it matters.

Sharon Arscott-Mills

Fellow / International Health

Sharon is a Fellow in International Health at ICF. Her exposure to the challenge of global health issues began as a child since her father was a doctor who established hospitals and nurses training institutions in rural Zambia and Angola. Several years ago, when she joined USAID as a Senior Technical Advisor for the Child Survival and Health Grants program she had the opportunity to explore and further her interest in solutions that have lasting impact on health through supporting the development of the Sustainability Framework within the PVO grants program. She has been a member of SHOUT since its inception. Her interest in CEDARS stems from a desire to explore some very fundamental questions about how we "do" development with colleagues who are asking similar questions Recent opportunities within ICF have enabled exploration of how to define and measure capacity and performance particularly within health system domains; and how to apply complex adaptive systems theory and social network theory to public health and development.

Sharon's work experience includes clinical intensive care nursing; computer software design; participatory community development; designing and implementing an injury surveillance program within the Ministry of Health in Jamaica, designing, monitoring and ensuring the quality of maternal child health, nutrition, family planning and HIV/AIDS programs within USAID in Washington and Nepal; and Clinical Services Team Leader for IntraHealth International. Sharon is a graduate of Rutgers, The State University of New Jersey, College of Nursing and Emory University's Rollins School of Public Health.

Anne Siegle

CEDARS Fellow / Food Security & Nutrition

Anne's international work began over 25 years ago as a volunteer public health nurse in a rural village of former Zaire. As she operated a mud hut clinic, maternity and hospital, worked with local healers and provided corresponding preventative outreach services to nearby villages, she witnessed first-hand the dramatic difference basic primary nutrition and health services and education can make in the lives of vulnerable populations. Anne went on to get a MPH in International Health from Johns Hopkins School of Public Health focusing on primary health care and health systems strengthening. Building from her community-based experience, Anne was led into the design, management and evaluation of relief, transition and development efforts that has taken her to over 30 countries (including countries in Africa, Asia, Latin America and Eastern Europe). She served with World Vision International for 15 years at the district, provincial, national, regional and global levels focusing on nutrition and health initiatives within the context of integrated multi-sectoral community development. She has taught nutrition, livelihood security and primary health care courses at both Johns Hopkins Bloomberg School of Public Health and Tulane University. In her current role at ICF as an International Nutrition and Public Health Technical Advisor, she provides leadership for the design of nutrition specific and nutrition sensitive interventions that contribute to sustainable livelihoods and improved nutrition outcomes among the most vulnerable segments of the population with a focus on the first 1000 day period.

Robb Davis, PhD, MPH

Robb has over 20 years of experience in international development in the field of maternal and child health. Robb's research and work have focused on community-based, participatory learning methods and how social capital is created and mobilized to shield people against risk. The proximity of concepts between social capital and community capacity, often referenced in sustainability discussions; and the linkages between risk mitigation / management and resiliency, bring exciting perspectives to our work on sustainability. On the occasion of ICF's special session on Climate Change, Food Security and Household Health at the 2010 Global Health Council, he led the writing of the Discussion Paper (see our first discussion forum) which stresses the salient role of social capital as a central and oft forgotten requirement of effective and sustainable adaptation strategy.

Robb is an accredited trainer with Global Learning Partners, and has extensive experience designing and leading dialogue-based trainings throughout Africa and Asia at both field-staff and trainer levels. Robb was the Executive Director of the Mennonite Central Committee, chairperson of the Child Survival Collaborations and Resources (CORE) Group and is adjunct faculty at Eastern Mennonite University's Summer Peace-building Institute and Eastern University's School of Leadership and Development.

His expertise helped to link these issues with CEDARS work in health and human development.

Quote: "If one does not know who is going to use the findings of one's research before conducting such research, particularly in the countries of South Asia and Sub-Saharan Africa, then one does not have the luxury of engaging in such research. It would be a sheer waste of time, money, and energy that could be better used in other pursuits".
