This important work has led to ongoing research collaboration with institutions around the world including Partners In Health (Peru), GHESKIO (Haiti), Harvard University (USA), University of Florida (USA), McGill University (Canada), Karuna Trust (India) and Stellenbosch University (South Africa). Exciting new research into Long COVID with Professor Bruce Brew, Steven Faux, and Lucette Cysique, as well as collaborating institutions in Australia and beyond, include the University of NSW, Curran Foundation, the Garvan Institute of Medical Research, the Kirby Institute, and Macquarie University.
