About Us

The Global Health Security Network (GHSN) Limited is a new multidisciplinary professional association dedicated to facilitating evidence- informed policy for the detection, prevention and control of infectious disease threats, irrespective of origin or source.

Following the inaugural Global Health Security Conference held in Sydney (18-20 June 2019), the Global Health Security Network was created to provide a space where global health academics, scientists and policy-makers from across multiple sectors and around the world have a platform to share their thoughts, ideas, research and innovations with other professionals. The Association was then founded in October 2019 by Adam Kamradt-Scott, Rebecca Katz (Georgetown University) and Sara Davies (Griffith University)


The Global Health Security Network (GHSN) is an international community of academics, scientists and policy-makers that welcomes professionals who seek to share their knowledge and research on global health security.

We encourage free thinking and support those that wish to make a meaningful impact to improve the health and well-being of all people globally. The GHSN community is an opportunity to engage with members, sharing their ideas through the Association and at GHSN events around the world.
