Roger Jenkins, dean of business at Miami University in Ohio, announced his retirement Monday, a week after it became public that he had returned to a court-appointed receiver $1.25 million in consulting fees from a man convicted of running a Ponzi scheme, The Dayton Daily News reported. In a memo to the faculty, Jenkins has denied wrongdoing, but noted that perceptions matter. "As with any deeply personal relationship and within every family, there are complex nuances that, if and when brought to light, due to surface appearance and the absence of context, are exceptionally difficult for others to understand,” he wrote. “And ironically, the reality is that perceptions matter. I have therefore concluded that my work here at the Farmer School will come to a close at the end of the semester, in no small part because this will complete a most unfortunate chapter in Miami’s history that has simply gone on too long."
