Postdoctoral Research Fellow

Australian Institute for Machine Learning - Projects

Faculty of Engineering, Computer and Mathematical Sciences

I'm a computer scientist and senior research associate in the School of Computer Science at the University of Adelaide, South Australia. I work in the Australian Institute for Machine Learning on numerous industry-inspired computer vision and machine learning problems.

When I am not engaged in a concrete industry project, my primary research endeavours are devoted to problems in projective parameter estimation, in the context of multiple-view geometry. The statistical estimation problems that I am interested in fall under the banner of non-linear errors-in-variables models.
