Roger Nash co-founded Fieldview Solutions and co-directed its work from 2008 to 2014, drawing from his diverse background of human rights and humanitarian field work in Colombia, Afghanistan, Sri Lanka, and Sudan. His academic work has focused on maximising the protective impact of UN field presence in conflict.

Roger began human rights field work supporting threatened rural communities and human rights activists in north-west Colombia with Peace Brigades International. He was the head of the UNHCR office in Batticaloa in eastern Sri Lanka during a period of rising tensions and intermittent displacement. He was later the Head of Mission of Médecins du Monde France in Afghanistan, and also worked as a child protection specialist with UNICEF in Sudan. Roger was a member of the International Council of Peace Brigades International from 2005 to 2010.

In 2007 he was awarded the SNELS prize from the University of Essex Human Rights Centre for his academic work on the creative use of field presence by UN human rights field missions.

Roger is currently a protection trainer for the OCHA ProCap program (Protection Standby Capacity) and a skills trainer for DPKO Civil Affairs. Since February 2010 he has been focussed on a global research study for the Office of the High Commissioner for Human Rights (OHCHR).
