Ada Sonnenfeld – Senior Expert – Monitoring, Evaluation and Learning

Ada is a Senior Expert within the Services Team at Integrity, based in London. She leads and supports the design and delivery of technical services in monitoring, evaluation and learning, including technical design, methodology and proposal development, technical delivery, project management and organisational learning.

Ada has substantial experience in design, monitoring and evaluation and results-based management for international development. During this time Ada worked on projects funded by clients including: BMZ, DFAT, EC, FCDO, GAC, KfW, SDC, UNHCR, USAID and the World Bank. Prior to working at Integrity, Ada led evidence synthesis research projects in peacebuilding and governance at the International Initiative for Impact Evaluation (3ie). These included systematic reviews of social cohesion programmes in fragile contexts and civic engagement in public service delivery, and evidence gap maps of peacebuilding and rule of law (forthcoming).

From 2014-2016, Ada worked with the Aga Khan Foundation in Afghanistan where she led the design and development of new programming in integrated rural development. This included developing theories of change and MEL frameworks for interventions in subnational governance, CDD, civil society, natural resource management, and market development. She led the business development team and quality-assured new contracts, project reporting and grant management.

Ada has carried out research and evaluations drawing on a variety of quantitative and qualitative methods. These include quasi-experimental impact evaluation, realist evaluation, participatory theory-based evaluation, and evaluability assessments. She has worked in diverse contexts, including four years based in fragile and conflict-affected areas. This has enabled her to engage with many types of stakeholders, from policymakers in Europe, to subnational government officials in rural Afghanistan; early childhood educators in Bangladesh and Cree Nation community members in northern Canada; civil society organisers in Argentina and refugees and asylum seekers in the United Kingdom.

Ada holds a BA in International Development, with a concentration in governance and civil society, from McGill University, and an MSc in Impact Evaluation for International Development from the University of East Anglia, where her research included a thematic focus on water security and a technical focus on theory-based impact evaluation of complex programmes.
