Biography

Graeme studied chemistry and computer science at The University of Newcastle (AU). He then did his PhD in chemistry finishing in 2004. 2005-2007 were spent as a postdoc first in Sweden and then Switzerland.

In 2007 Graeme returned to Newcastle and joined CSIRO as a postdoc, transitioning to a Research Scientist after about one year. In 2012 Graeme took on the role of Team Leader and currently leads the Zero Emissions team within the Sustainable Carbon Technologies Group. He also collaborates widely with universities and co-supervises a number of PhD students.

Graeme has published over 80 journal articles, 4 book chapters and holds 7 patents. He is also involved with the Scientists and Mathematicians in Schools and the ASSETS Summer School for indigenous students.

Research Focus
The chemical and physical processes involved in the separation of carbon dioxide and other acid gases from gas mixtures, and their potential transformation into valuable materials. Both from the perspective of measuring what is happening and building predictive models to simulate what is happening.

By understanding in detail the mechanisms of these processes improvements can be made to the gas absorbing materials, chemical transformation steps and the design of the overall separation process. These improvements come from a combination of chemical insights and simulations used to guide the research focus.

Carrying out this research couples chemical kinetics, equilibria and thermodynamics with mass and heat transfer processes.
