Professor Igor Aharonovich
Igor Aharonovich received his B.Sc (2005) and M.Sc (2007) in Materials Eng from the Technion – Israel Institute of Technology under the supervision of Prof Yeshayahu Lifshitz. He then moved to Australia and pursued his PhD studies at the University of Melbourne under the supervision of Prof Steven Prawer. During his PhD, Igor developed experimental techniques to engineer novel, ultra bright single photon emitters in diamond.
In 2011, Igor took a postdoctoral position at Harvard University at the group of Prof Evelyn Hu. His research was focused on nanofabrication of optical cavities out of diamond, SiC and GaN. He also carried out nanophotonic experiments including coupling of emitters to optical cavities, turning of cavity resonances and low temperature high resolution spectroscopy.
In 2013 Igor has joined the University of Technology Sydney, where he leads the quantum nanophotonics laboratory. His research is focused on exploring single defects in wide bandgap semiconductors for quantum technologies. Specifically, his team was the first to discover single emitters in hexagonal boron nitride and the first to isolate spin defects in this material. In 2018, together with Carlo Bradac, Igor co-founded http://www.writeitupnow.com – a scientific writing company that assists scientists in communicating their scientific results.
Igor received several international awards including the CN Yang Award – honors young researchers with prominent research achievements in physics in the Asia Pacific region (2019), the Pawsey medal from the Australian Academy of Science (2017), David Syme Research Prize (For the best original research in biology, physics, chemistry or geology, produced in Australia during the preceding two years (2017), the IEEE Photonics Young Investigator Award (2016)
Professor Milos Toth
Milos Toth received a PhD in 2001 from UTS where he worked on the luminescence properties and defect structure of wide bandgap semiconductors. He subsequently worked as a postdoctoral researcher at Cavendish Laboratory, University of Cambridge, and a research scientist at FEI Company laboratories in Boston, Massachusetts and Portland, Oregon (USA). His work in industry was focused on the research and development of charged particle beam nanofabrication and analysis techniques.
Milos returned to UTS in 2011 to take up a Professorial Chair, and to set up a research group working on the development of self-assembly and top-down nanofabrication techniques, and their application to optoelectronic materials. His current work is focused on 2D materials and wide bandgap hosts of singe photon emitters.

Dr. Anastasia Zalogina
Dr. Anastasiia Zalogina is a Chancellor's Research Fellow at UTS, starting in 2024. She completed her PhD in Physics at the Australian National University (ANU) in 2022, where she specialized in beam shaping and light control. Her work included structuring light to carry orbital angular momentum, modifying phase and polarization, exploring the interaction of structured light with nonlinear processes, and enhancing emission from single-photon sources.
Following her PhD, Dr. Zalogina joined the University of Adelaide as a Postdoctoral Researcher from 2022 to 2024. During this time, her research focused on developing sensing devices based on the orbital angular momentum of light for refractive index detection in surrounding media.
