In this thesis I undertake four projects that investigate the influence of network topology on financial contagion. In the first project I study the ability of three net- work models to reconstruct the topology and contagion dynamics of a real interbank network. This allows me to identify the main topological properties of networks that affect financial contagion. In the third and fourth projects I develop a framework to reverse stress test interbank networks. Based on this framework I propose a strategy to reduce systemic losses and I test the strategy in interbank networks with different topologies. I develop the methodological background to the reverse stress testing framework in the second project. In this project I study network control theory, to investigate the influence of network topology on the cost of managing the dynamics of networks.
