Executive Committee

Executive Committee


All policy and programmatic issues associated with research performance and future directions of the Observatory, including interactions with affiliated Earth Institute and other Columbia units and groups, both on and off the Lamont campus as they pertain to the intellectual vigor of the Observatory. Will advise on the incorporation of new units having direct intellectual ties to the Observatory, particularly if they are to be located on the Lamont campus. Will carry out research and other planning activities, including identification of appointment needs through a Planning Sub-committee (see below). Will appoint other standing and/or ad hoc sub-committees for specific tasks. Will consult on recommendations to the Directorate made by the Promotion and Careers Sub-Committee (see below) concerning all research grade promotions and appointments. Any matter not resolved in the Executive Committee shall be referred to a meeting of the Observatory Senior Staff at the request of any member of the Executive Committee.


The Executive Committee is chaired by the Lamont Director.

The senior staff representative from each research division are elected by ballot by the Observatory research staff of the appropriate division. The junior staff representative is appointed by the Director, from nominations received from the research divisions. Those members elected or appointed following recommendation to the Director will serve three year terms.

The ex-officio members include the Lamont Administrator, a representative of the technical staff, and the Associate Director for the Office of Marine Operations. Additional ex-officio members representing units or groups with which the Observatory has direct research or academic ties can be included on the Executive Committee by vote of the existing members. The Executive Committee is free to request members of the Observatory or others to participate in its meetings where additional input is desired.
