Professor Kristina Vušković


Professor Vušković was awarded a BA in Mathematics and Computer Science from New York University in 1989, and a PhD in Algorithms, Combinatorics and Optimization from Carnegie Mellon University in 1994.

She spent two years as an NSERC Canada International Fellow at University of Waterloo, Department of Combinatorics and Optimization, which was followed by a position at the Department of Mathematics of University of Kentucky.

Since 2000 she is at the School of Computing, University of Leeds, where she is the leader of Algorithms and Complexity Research Group. Professor Vušković was awarded Chair in Algorithms and Combinatorics in 2011.

See the Algorithms and Complexity research group page for further information.

Research interests

Kristina's research interests are in graph theory, combinatorial optimisation and algorithms. Kristina's present research involves structural analysis of hereditary graph classes, and exploiting structure for construction of efficient algorithms.

Current research grant:
