Adjunct, Emeritus and Engineering Staff

Adjunct Scientists

Adjunct appointments are made for part-time service and are renewed annually. Normally, Adjuncts are individuals engaged in research at the Observatory while working simultaneously at the institution of their primary affiliation.

The level of an Adjunct appointment begins at the Associate Research Scientist level.

To seek a new appointment, a supporting memo outlining the proposed research, including the candidate's curriculum vitae, should be submitted to the Director.

Scientists Emeritus

Any member of the Senior Staff of the Observatory in good standing at the time of retirement may request to become a Scientist Emeritus.

Appointment requires approval of the Director and of the Executive Committee.

A Scientist Emeritus may participate in Senior Staff meetings as a non-voting member. A Scientist Emeritus appointment allows the recipient to use LDEO facilities, subject to their availability and in accordance with rules established by the Director, and to serve as co-Principal Investigator on proposals.
