Beyond his role as an administrator, Brandt has become known for his warm personality and genuine dedication to the needs of his colleagues and of his students.

“He’s a truly fantastic fellow,” said Eli Tziperman, director of graduate studies for earth and planetary sciences.

In addition to his administrative role, Brandt holds joint appointments at Harvard Medical School and the history of science department.

“[Teaching] is something he’s been able to continue actively during the time he’s been dean,” said James M. Hogle, Dudley House Master and director of graduate studies for biophysics. Hogle added that he appreciated that Brandt was an “ardent supporter” of Dudley House.

Although Brandt does not plan to return as dean, he does intend to resume teaching duties upon finishing medical treatment.

“I will greatly look forward to my return to the faculty and to re-engaging in the critically important work of graduate education,” he wrote in his email.

Richard J. Tarrant, Pope Professor of the Latin Language and Literatures and acting dean of GSAS from 1995 to 1996, will serve as interim dean while Brandt’s replacement is found.

Smith and Brandt approached Tarrant last weekend to request that he serve as interim GSAS dean. Tarrant accepted the appointment after conversations with both administrators on Tuesday.

“My highest priority is to ensure as smooth a transition as possible, so that the work of GSAS can be successfully carried on through the end of the academic year,” Tarrant wrote in an email to the Crimson.

“He knows the graduate school well and the administration well,” said Margot N. Gill, GSAS administrative dean.

The search for Brandt’s permanent replacement is in its initial stages, according to FAS spokesperson Jeff Neal. Smith has invited members of the FAS community to send him their thoughts on potential candidates.
