László A. Végh
Associate Professor

I am broadly interested in fundamental questions in algorithms and optimisation: exact and approximation algorithms for problems related to network design, flows, matchings, and equilibrium computation, with a particular focus on strongly polynomial computability.
I completed my PhD in mathematics at the Eötvös University in Budapest in 2010, under the supervision of András Frank, working in the Egerváry Research Group on Combinatorial Optimization. In 201112, I was a postdoctoral fellow with Vijay Vazirani at the Georgia Institute of Technology, in the School of Computer Science. I joined the Operations Research Group at LSE in 2012.
