Principal Investigator

Flora Rutaganira
Assistant Professor of Biochemistry and Developmental Biology
Flora received her B.S. in Biochemistry and Molecular Biology from UC Davis and her Ph.D. in Chemistry and Chemical Biology from UC San Francisco under the mentorship of Prof. Kevan Shokat. In 2017, she became fascinated by choanoflagellates and joined the laboratory of Prof. Nicole King at UC Berkeley as an HHMI Hanna Gray Postdoctoral Fellow. Based on her research on choanoflagellate kinase signaling in the King lab, Flora started her lab, the FUNR lab to study the origin of cell communication in animals at Stanford University in the departments of Biochemistry and Developmental Biology. She hopes that the work in her lab will uncover how molecule sensing was integrated with core signaling pathways during the evolution of animals, and uncover core principles of animal cell signaling.
