He completed his doctoral studies at the University of Melbourne in 2001 under the supervision of Jason Mattingley and William Webster, where he developed models of visual short-term memory.
He argued along with his collaborator Wei Ji Ma that the capacity limits commonly seen in visual short-term memory and change blindness are caused, not by a high-level bottleneck in the number items that can be attended and/or stored in memory, but by an increase in neuronal noise in stimulus representations as complexity of visual information increases.
In 1993, he founded the electronic journal Psyche (with Kevin B Korb, Monash Univ), which in addition to publishing peer-reviewed papers and book reviews, acted as an online forum for discussion of consciousness studies via its lively mailing list Psyche-D.
However, while at Cell Press he remained active with the ASSC (e.g., visiting Taipei twice to help the local organizers of the 2008 meeting).
However, internal politics on the Board led to his being frozen out of further involvement with the organization he had helped to create at the completion of the meeting.
