After 20-some years leading humanitarian and post-conflict emergency medical teams in former Yugoslavia, sub Saharan Africa and south Asia, Jonathan felt like he was waking up everyday going to work to deal with the humanitarian fallout of a sick planet. Believing that our planet is the patient now, and understanding that we've never lived in a world where the health of people, ecosystems, and the planet could be addressed in silos, he became increasingly focused on the drivers of climate breakdown and nature's collapse - and became particularly interested in operationalizing the fundamental interdependence between human well-being and ecosystem integrity. He followed his vision for change into the new field of Planetary Health and became Executive Director of Health In Harmony in early 2017. He has written and published broadly about the impact of Health In Harmony's work. Just prior to joining Health In Harmony, he spent 13+ years in leadership roles globally with Doctors Without Borders. Jonathan holds an MS in Conservation Biology and Applied Ecology and an MA in Politics and International Security.
