Pieter Kleer received both his BSc and MSc in applied mathematics from the Delft University of Technology (in resp. 2013 and 2015). His master thesis was on "Distributed route discovery in communication networks using neighbour information", in cooperation with TNO. In September 2015 he started as a PhD student at the Centrum Wiskunde & Informatica (CWI) in Amsterdam, under the supervision of Prof.dr. Guido Schaefer and Prof.dr. Lex Schrijver. His main research interests are in discrete optimization and (algorithmic) game theory.

Currently, his project focuses on quantifying the inefficiency of selfish behaviour in extensions of classical congestion models. In a (network) congestion game, there is a set of players all controlling a certain amount of flow, that has to be routed from a source to destination in the network as fast as possible. All players are selfish and only care about the travel time of their own flow. As a result, very inefficient outcomes can arise in the network (in terms of average travel time in the network). Pieter studies various extensions of classical game-theoretical models from a theoretical point of view, for example, what happens to inefficient outcomes if players use perturbed information for making their routing decisions?
