About Delia

Delia Welsh is an expert in monitoring and evaluation of international development programs.

Welsh recently served as the senior director for the Goldilocks Initiative at Innovations for Poverty Action (IPA), developing guidance and resources for funders, nonprofits and social enterprises to ensure their data collection systems balance the need for evidence of impact with operational data to inform management decisions. She also served as IPA’s deputy executive director for research and policy, supporting the organization’s project development, policy, and communications functions, in addition to overseeing research initiatives in financial inclusion, entrepreneurship, and post-conflict recovery. 

Welsh previously was part of the small team tasked with defining and setting up the Millennium Challenge Corporation (MCC) and held several positions within the organization. She served as director for impact evaluation, managing development of impact evaluation plans and hiring of independent evaluators to conduct program evaluations, and training staff and partners. She also was responsible for developing the monitoring and evaluation plans for several MCC Compacts, including Benin, Cape Verde, Morocco, Madagascar, and Senegal. 

Welsh was also a program examiner at the Office of Management and Budget, supporting the creation of the MCC and providing budgetary oversight of several U.S. foreign assistance programs. Welsh holds a master’s of public administration from the Woodrow Wilson School at Princeton University and was a Fulbright Fellow in Morocco.
