Hello and welcome!

Here you’ll be able to learn a little bit about me from an academic point of view. Happy reading!

I am a physician-scientist combining the roles of the Founding Director of Centre for Population Health Sciences at LKC Medicine, joint new Medical School between Imperial College London and Nanyang Technological University, Singapore, a Reader in Primary Care and eHealth at Imperial College, and a practicing family physician.

Throughout my career I blended academic, policy, management and clinical work. I served in a wide range of roles including Founding Global eHealth Unit, as a Director of Public Health and Primary Care and Lead Director for Integrated Care at Imperial College Healthcare NHS Trust (one of the largest hospitals in Europe) until 2014, Director of National Institute of Health Research (NIHR) Primary Care Research Network and co-director of NIHR Comprehensive Local Research Network for London (NW), Medical Director and Chair of a Professional Executive Committee of a Primary Care Trust, Primary Care and Research Adviser to the Editor of the BMJ, a founding director for the Imperial GP Specialty Training, a member of Imperial College’s School of Public Health board, a member of International Advisory Board for City of Rotterdam, an adviser to the OECD, the Global Fund to fight AIDS, Tuberculosis and Malaria, World Bank and others. I continue to serve in a range of other roles including as a Board Member of the BMC MedicineJournal of Global Health; an Editor of the Cochrane Collaboration and Visiting Senior Researcher, Department of Family Medicine, University of Ljubljana.


For me research could be summarized in three words: think, play, do. It is about creating new ideas, thinking about new options and playing with them to see if they are practical, beneficial and economical, and then doing: making the research real. Each of these steps - think, play, do endures rigorous scientific analysis.

My research and policy work spans wide areas and disciplines encompassing eHealth, health systems and population health research, innovation and implementation. I am passionate about blending my multifarious expertise into a perspective that spans the dimensions and enables me to bring fresh ideas, leadership, strong rooting in evidence-based medicine and boldness for making a difference.

Global eHealth Unit’s mission is to develop models of care that are personalized; integrate and synergize healthcare delivery by deploying information technologies to their full potential; and provide continuously improving high quality care to all while empowering individuals and populations. We want to achieve this in both international resource-limited settings and domestic resource-rich settings.

Teaching and supervision

I like to teach. Hardly anything can be as challenging as being a good teacher. Why? Because “setting an example is not the main means of influencing another, it is the only means.” (Einstein)

I supervise PhD and Masters in Public Health students. If you are interested in doing a PhD or research internship at the Global eHealth Unit you are very welcome to get in touch.

Clinical work

I greatly enjoy my clinical work with patients. It’s fantastic to be able to combine clinical work with my other roles - they enrich and inform each other.

Free time activities

OK, I’ll share a little bit of personal information too. I have never been quite able to decide whether I more like mountains or sea. So I tend to go to both. Below is a photo of one of my favourite Croatian islands.
