ATAC Membership

There are seven members on ATAC, with at least one international member. In addition, a substitute member will also be appointed, to take the place of an ATAC member who is unavailable for a meeting of the committee.

Appointment to ATAC will usually be for a 3-year term, although the appointments may be for staggered terms to ensure a steady turnover in membership.

Nominations to the committee will be periodically solicited by the AAO Director via an open call to the community.  The AAO Director and the AAO Advisory Committee will review the nominations, when making recommendations to the Departmental Secretary, to ensure suitable representation on ATAC, encompassing a broad spread of specialisations and seniorities.  The Departmental Secretary delegates the appointment of a Chair, Deputy Chair and membership to the AAOAC.

An AAO staff member may be appointed to ATAC, although (as for other institutions) normally no more than one AAO representative would be on the committee at a time.


Dr Lee Spitler AAT Technical Secretary
Dr Stuart Ryder Gemini & Magellan Technical Secretary
