Ph.D.s 1980-1989

Following the record 117 mathematics doctorates awarded at Cornell during the previous decade, only sixty one were awarded from 1980 to 1989. Thirteen went to women.

Thirty three faculty supervised at least one Ph.D.s during this decade. Anil Nerode (6) and John Hubbard (5) were the most active, followed by Louis Billera, Kenneth Brown, Marshall Cohen, Leonard Gross, Stephen Lichtenbaum, Lawrence Payne, Alex F.T.W. Rosenberg and Richard Shore (3).

In 1986, the Mathematical Science Institute was created under the leadership of Geoffrey Ludford, Professor of Theoretical and Applied Mathematics, and with the help of Charlie Van Loan (Computer Science), Lars Wahlbin (Mathematics), and Narahari Prabhu (OR-IE). It was supported for ten years by a grant from Army Research Office.
