Former University of Nebraska President James B. Milliken, who has served as chancellor of the City University of New York since 2014, said Tuesday he will step down at the end of the school year.
Milliken, 60, was diagnosed with throat cancer in April and has undergone months of radiation and chemotherapy, he wrote in a message to the CUNY community Tuesday.
While he said he feels healthy and expects to be "active and working for many more years," additional health challenges will require his attention "in the months ahead."
"The business about learning more about yourself and gaining new perspective when faced with such challenges has certainly proved to be the case with me," Milliken wrote. "The experience has given me an even deeper commitment to enjoying fully my work, my family and friends, and my life."
Milliken said a nearly new board of trustees charged with oversight of CUNY "will have their own ideas about CUNY, and they should have the opportunity to help shape the leadership and agenda for the future."
The Fremont native was president of NU from 2004 to 2014, while previously serving as an administrator at the University of North Carolina system and as a former vice president for external affairs at NU from 1988 to 1998.
Milliken said he is looking forward to ending his time at CUNY with spring graduation ceremonies.
"I have been given one of life's great gifts — the chance to do something I love that has a positive impact on many," he said. "I will always be grateful for that opportunity and for the relationships I have had with students, faculty and staff of The City University of New York."
