Ivan J. Santiago, PhD, is Puerto Rican and was raised in the Mott Haven neighborhood of the South Bronx. He attended the City College of New York, where he obtained both bachelor’s and master’s degrees in biology. Next, he attended Harvard University, where he earned a PhD in neurobiology. During this time, Dr. Santiago earned the 2016 Howard Hughes Medical Institute (HHMI) Gilliam fellowship.

Dr. Santiago’s doctoral studies were aimed at determining the design principles underlying neuronal wiring during development.
