Ana Bela Cruzeiro (born 1957)[1] is a Portuguese and Swiss mathematician whose research concerns stochastic analysis and the Malliavin calculus, as well as the differential equations used to model fluid dynamics and quantum mechanics.
She is a professor of mathematics at the Instituto Superior Técnico, part of the University of Lisbon.
[2] After earning a master's degree in mathematics at the University of Lisbon in 1980, Cruzeiro studied mathematics at Pierre and Marie Curie University in Paris, earning a diplôme d'études approfondies in 1982, a doctorat de troisième cycle in 1983, and a doctorat d'état in 1985.
[2] Her 1985 doctoral dissertation, Equations différentielles ordinaires et équations différentielles stochastiques sur l'espace de Wiener, was supervised by Paul Malliavin.
[2] She has been on the faculty of the University of Lisbon since 1986, and became a full professor in Instituto Superior Técnico in 2002.
