Sandy OliverSandy Oliver is Professor of Public Policy at UCL Institute of Education and Deputy Director of SSRU and its EPPI-Centre. For twenty five years her interests have focused on the interaction between researchers and people making decisions in their proessional and personal lives. With this in mind she has been developing methods to collate knowledge from whole bodies of research - systematic reviews - not just single studies. Most recently this has been in the area of international development where she has conducted systematic reviews and built up a programme of support for research teams conducting reviews elsewhere. She works with DFID and the Alliance for Health Policy and Systems Research at WHO to build capacity in systematic reviewing in developing countries.
