Two top administrators at the University of Medicine and Dentistry of New Jersey handed in their resignations on Thursday, as a new report apparently questioned their use of travel and expense accounts. The Star-Ledger, a local newspaper, first disclosed the sudden resignations of R. Michael Gallagher, dean of the university’s School of Osteopathic Medicine, and Robert A. Saporito, senior vice president for academic affairs.

The report, by a federal monitor appointed to oversee the troubled public health-sciences institution, was not made public, but sources told The Star-Ledger that it questioned whether hotel and travel expenses filed by Mr. Saporito were for university business. It also found that Mr. Gallagher had had his university driver run personal errands for him and had misused his expense account to purchase gifts and pay for his membership in an exclusive country club.

Mr. Gallagher declined to comment on his resignation, while Mr. Saporito told the newspaper that he wanted to allow the university’s interim president, Bruce C. Vladeck, who just took office (The Chronicle, March 2), to reorganize the administration.

The report is the latest in a wave of allegations of financial mismanagement, influence peddling, and potential criminal misconduct to hit the Newark-based institution. Earlier this month, auditors found that university officials may have overbilled the Medicaid program by as much as $70-million over the last decade (The Chronicle, March 9).
