Biography

My PhD was awarded for using UV/visible lasers and molecular calculations to understand chemical reactions relating to silicon and germanium thin-films. Postdoctoral research at Flinders resulted in the development of a powerful laser-based technique for studying molecules and small clusters.

At Flinders I am involved in teaching for physics and chemistry topics. I have worked previously in Research Administration - managing the Researcher Mentoring Scheme, supporting ARC grant applications and the ERA 2015 submission.

Qualifications

PhD: Laser studies of silylene and germylene - experiment and computation, Flinders University (2001).

Honours: Synthesis and laser studies of air-sensitive light-activated molecular switch compounds containing iron, Flinders University (1993).

Teaching interests

Other teaching responsibilities:

CHEM1201 - General Chemistry - Academic Developer and Demonstrator

PHYS1702 - Physics for Health Sciences - Demonstrator

I have also taught in the RHD Professional Development Program.

Topic Lecturer:

Research interests

Weak molecular interactions studied using lasers and ab initio computational chemistry methods.
