An investigation into the misuse of funds by a University of Iowa physics professor reveals nearly $100,000 in improper disbursements and undeposited conference registration fees. The audit was requested by the university after some issues were raised surrounding Professor Michael Flatte. In a statement, the university says it's reviewing possible disciplinary action and the auditor's recommendations. State Auditor Mary Mosiman says the university should implement procedures to ensure compliance with policies by employees.
