Tim has extensive experience in quantum optics and optical implementations of quantum information techniques. His postdoctoral experience was at the Australian National University, the University of Auckland and the University of Queensland. He was awarded an ARC QEII Fellowship in 2000 and an ARC Professorial Fellowship in 2006.

In his role as leader of the Optical Quantum Computation Work Package within the Centre, Tim oversees experimental and theoretical programs at the University of Queensland, Griffith University, the Australian National University and UNSW Canberra, that seek to demonstrate the feasibility of quantum computation based on optical circuits, single photon sources, quantum memory and electro-optic feedforward techniques. He is also Node Director at the University of Queensland and a member of the Centre Executive.

Tim has over 200 publications that have attracted over 4500 citations. He has co-authored a textbook that has sold over 1500 copies and has authored and co-authored 5 invited book chapters. His publications appear in high quality international journals including 23 in Physical Review Letters, 6 in the Nature suite of journals, as well as articles in Science and Reviews of Modern Physics. Tim’s h-index is 36. He has performed consultancy work for Quintessence Labs; the Defense Science and Technology Organization; and Lockheed-Martin, Australia. He was the Australian Institute of Physics Youth lecturer in 2003 and regularly gives seminars to High School and Primary School students. Tim was admitted as a Fellow of the Australian Academy of Science in 2017.


Tim's research seeks to demonstrate the feasibility of quantum computational gates based on linear optics, single photon sources and electrooptic feedforward techniques.
