Xenia de la Ossa

Xenia de la Ossa Osegueda (born 30 June 1958, San José, Costa Rica) is a theoretical physicist whose research focuses on mathematical structures that arise in string theory.

[2] Xenia de la Ossa received her PhD from University of Texas at Austin with the dissertation Quantum Calabi-Yau Manifolds and Mirror Symmetry written under the supervision of Willy Fischler.

In 1991, she coauthored "A pair of Calabi-Yau manifolds as an exactly soluble superconformal theory",[6] which contained remarkable predictions about the number of rational curves on a quintic threefold.

As the mathematician, Richard Thomas, of Imperial College London remarked to me, in an e-mail message: ‘’ I can’t emphasize enough how deep some of these dualities are: they constantly surprise us with new predictions.

[18] She has also been principal investigator for the project entitled Vacuum States of the Heterotic String,[19] supported by a grant from the Engineering and Physical Sciences Research Council (EPSRC).
