In late 2011, Fields became an associate professor at Florida International University's Nicole Wertheim College of Nursing and Health Sciences and served as the first-ever assistant dean of clinical affairs and health policy, as well as the co-director of the Doctor of Nursing Practice (DNP) program. Fields left Florida in January 2015 to be the dean of the Mervyn M. Dymally School of Nursing at Charles R. Drew University of Medicine and Science in Los Angeles, California. This appointment made Fields one of the youngest nursing deans in the country.
