Ann Roberts obtained B.Sc. (with First Class Honours and University Medal) and Ph.D. degrees in physics from the University of Sydney in Australia. After a position as a postdoctoral associate in the School of Electrical Engineering at Cornell University, she accepted an academic position in the School of Physics at the University of Melbourne where she is now Professor. Professor Roberts has diverse research interests in physical optics and photonics. In particular, she has had a long-term interest in diffraction theory and modelling that originated in her PhD research where she applied rigorous vector theories to study the transmission of light through subwavelength apertures and periodic structures. This research was subsequently extended to experimental investigations of millimeter wave devices and, most recently, materials for use in the near-infrared and visible regions of the electromagnetic spectrum. In particular, she has made significant advances in the computational and experimental study of plasmonic devices, metamaterials and nanoscale antennas.
Prof Roberts' research interests also include the development of novel microscopic and imaging techniques and their application to the non-destructive examination of specimens such as photonic devices and cultural materials.
Prof Roberts is a Fellow of the Australian Institute of Physics (and former Victorian Branch Chair), a Senior Member of the Optical Society of America and immediate Past President of the Australian Optical Society.
