University of Miami (1968–1974) and the
George Washington University (1970–1975). She was also an affiliate professor of biology at
George Mason University (1994–2000) and a member of the graduate faculty at the
Florida Institute of Technology (1996–2000). Rice mentored many students, including those developing the
Evo-Devo approach, and advised over thirty postdoctoral fellows and eight short-term graduate fellows. She served as a committee member for thirteen doctoral candidates. Rice was also responsible for the creation of the Smithsonian Marine Ecosystem Exhibit . Working with nearby officials, she developed the St. Lucie County Marine Center, a county-run facility where the exhibit is housed. Located opposite the Smithsonian Marine Station, the focal point of the exhibit is an enormous 3,300-gallon coral reef aquarium that was previously displayed at the National Museum of Natural History in Washington. == Publications ==
