Chris Callaghan, M.Sc.
Matthew Spencer, Ph.D.
Principal Scientist

A native Montréaler, Chris studied math, chemistry and physics at Dawson College in the mid-80’s. He then went on to earn a B.Sc. from McGill in natural history and wildlife science, and an M.Sc. from the University of Ottawa, with a focus on how human activities affect natural ecosystems. Chris entered the Canadian federal public service in the early 90s, where he took on various positions related to environmental toxicology, ecosystem management, sustainable development and environmental auditing. It was during his time with the Auditor General of Canada that Chris became interested in the policies and frameworks associated with measuring organizational performance and accountability. In 2006, Chris opened his own consulting firm specializing in program evaluation. As he gained insight into some of the challenges associated with program evaluation theory and practice, he observed what he sees as serious gaps in how interventions are designed and measured. Chris is now concerned with developing better means to understand how interventions work, how to improve design processes, and how to support evidence-informed decision-making. His vision is a world in which decision-making is systematically supported with evidence, including research, expert knowledge, stakeholder narrative, and open/big data. To realize this vision, Chris is focused on the use of cutting-edge concepts and technologies, including those associated with data science and artificial intelligence, to gather, analyze and test the evidence needed to bring policy-making into the modern era.
