Alan Duffy

Research Fellow, Swinburne University of Technology

I'm a theoretical astrophysicist and cosmologist, investigating how galaxies form, the nature of dark matter and the large scale properties of the Universe.

To study the evolution of galaxies and their interaction with dark matter, I create billion-particle model universes on supercomputers around the world.

This has resulted in numerous refereed research articles, public interviews and presentations at both Universities/Conferences and public outreach events ranging from planetarium shows to pubs.

I am particularly excited by spreading the latest discoveries to as wide an audience as possible.

Outreach - why reach out?
