Steven Chapman became Chief Conservation Officer in 2013 and is responsible for the strategic leadership and management of WWF’s conservation programs team, including strategy and science, field programs, market transformation and policy. Previously, he was the Chief Technical Officer for Population Services International and led efforts to improve intervention effectiveness, cost-effectiveness and equity in malaria and child survival; HIV, tuberculosis and reproductive health; research & metrics; social marketing; and learning. He also headed PSI's strategic initiative on innovation, which aimed to increase the proportion of health impact produced by PSI from new interventions, and consisted of an innovation fund, cross departmental innovation teams, capacity building efforts and pilot projects.
From 2002 to 2008, Steven led PSI's Research & Metrics department and its initiative to increase evidence-based decision making across the organization. This effort resulted in PSI interventions increasingly using standard methods and tools to segment populations, plan interventions, and monitor and evaluate behavioral determinants and outcomes and health impact.
Steven was a Peace Corps Volunteer in Togo. He first joined PSI in 1989 as special projects officer and in 1996 became the founding director of PSI Europe. From 1997 to 1999, he was Director of Asia Programmes for Marie Stopes International.
