About

I am a researcher in mathematics. My research interests are nonsmooth optimisation, approximation theory, and their applications.

I obtained my PhD in 2005, under the guidance of Prof. Alexander Rubinov. I then worked at the University of Ballarat/Federation University for 12 years, first as a research fellow, and then as a lecturer in mathematics. I am now with the school of Information Technology at Deakin University. I am also a honorary research fellow with CIAO at Federation University.
