Cornelia Druţu is a Romanian mathematician notable for her contributions in the area of geometric group theory.[1] She is Professor of mathematics at the University of Oxford[1] and Fellow [2] of Exeter College, Oxford.

## Education and career

Druţu was born in Iaşi, Romania. She attended the Emil Racoviță High School (now the National College Emil Racoviță[3]) in Iaşi. She earned a B.S. in Mathematics from the University of Iaşi, where besides attending the core courses she received extra curricular teaching in geometry and topology from Professor Liliana Răileanu. [2]

Druţu earned a Ph.D. in Mathematics from University of Paris-Sud, with a thesis entitled Réseaux non uniformes des groupes de Lie semi-simple de rang supérieur et invariants de quasiisométrie, written under the supervision of Professor Pierre Pansu.[4] She then joined the University of Lille 1 as Maître de conférences (MCF). In 2004 she earned her Habilitation degree from the University of Lille 1.[5]

In 2009 she became Professor of mathematics at the Mathematical Institute, University of Oxford.[1].

She held visiting positions at the Max Planck Institute for Mathematics in Bonn, the Institut des Hautes Études Scientifiques in Bures-sur-Yvette, the Mathematical Sciences Research Institute in Berkeley, California. She visited the Isaac Newton Institute in Cambridge as holder of a Simons Fellowship [6].

She is currently chair of the joint scientific committee of the European Mathematical Society and European Women in Mathematics.[7]

## Awards

In 2009, Druţu was awarded the Whitehead Prize by the London Mathematical Society for her work in geometric group theory.[8]

In 2017, Druţu was awarded a Simons Visiting Fellowship [6].

## Publications

### Selected contributions

• A classification of relatively hyperbolic groups up to quasi-isometry; the fact that a group with a quasi-isometric embedding in a relatively hyperbolic metric space, with image at infinite distance from any peripheral set, must be relatively hyperbolic.
• The quadratic filling for certain linear solvable groups (with uniform constants for large classes of such groups).
