Joep Lange established the Amsterdam Institute for Global Health and Development (AIGHD) in 2009 and uniquely positioned it to fill the gap of the ‘delivery perspective’ which has been largely neglected in academic approaches to global health. AIGHD links disciplines, resources and innovative programs from academic institutions and implementing partners in both the developed and developing world, with the ultimate aim to lead the way to access to high quality health care for all inhabitants of this world. Lange also served on Accordia Global Health Foundation's Scientific Advisory Board.
