Marian Gidea


Professor, Associate Dean for STEM Education and Research, Director of the Graduate Program in Mathematical Sciences

PhD, SUNY at Buffalo, 1997
Master of Science, University of Bucharest, 1992

Marian Gidea joined Yeshiva University in New York City in 2013. He held previous appointments at the Mathematical Sciences Research Institute in Berkeley (research professor, 2018), the Institute for Advanced Study in Princeton (member, 2011-2013), Northeastern Illinois University (tenured professor, 2000-2013), Northwestern University (visiting assistant professor, 1999-2000), Loyola University Chicago (visiting assistant professor, 1997-1999).

Between 2021-2022 he served at the National Science Foundation as a program director in the Mathematical Sciences Division. This distinction is reserved only for the most accomplished researchers in their respective fields. In this annually rotating role, Dr. Gidea guided and evaluated research at the national level.
