Cutting-edge research at 2023 National Science Week

What are the scientific research topics that our leading research institutions are excited about?

National Science Week is a time for our universities and affiliated research institutions to showcase their leading science communicators, celebrate their research successes, and provide opportunities for PhD students and early career researchers to talk to the community and inspire a new generation in the possibilities of a STEM career.

There are over 100 researchers involved in events across NSW this year, some for their own institutions, but many in community events in libraries, parklands, gardens, art galleries and cultural institutions.

The University of Sydney , UNSW Sydney, UTS Sydney and Macquarie University have their fabulous National Science Week events grouped online (thank you!), and below is a curated selection of highlights, grouped by disciplines. We’ll keep updating the list as new events are announced.
