Since 2012, Künzli is Co-Editor in Chief of the International Journal of Public Health (owned by the Swiss School of Public Health, published by Frontiers, Lausanne). Under his lead, IJPH became fully self-funded as he negotiated the share of revenues with SpringerNature. The Open Access publishing contract with Frontiers guarantees not only the coverage of all costs of both SSPH+ journals (namely the independent Edtorial Office, hosted by Swiss TPH) but results in additional revenues for SSPH+ in support of authors from low-income countries and the development of the journals and the PhD training offers of SSPH+.
