My research expertise fits within the domain of health systems research. It can be divided along three main areas: 1) Diversity and Multi-morbidity; 2) Intra, Extramural and Intersectoral Collaboration; 3) Health information and health information systems. Methodologically, I have focused on implementation research and on multi-country case studies, with the focus on reciprocal learning. I am also a visiting associate professor at the National University of Singapore, Centre for Research in Health System Performance & Department of Family Medicine.
