Our papers are the official record of our discoveries. They allow others to build on and apply our work. Each paper is the result of many months of research, so we make a special effort to make them clear, beautiful and inspirational, and publish them in leading journals.

FCMDGVSB Mathematical FinanceNetwork valuation in financial systems
Consistent valuation of interbank claims within an interconnected financial system can be found with a recursive update of banks' equities.

FV Journal of Economic Interaction and CoordinationBursting dynamic networks
A mathematical model captures the temporal and steady state behaviour of networks whose two sets of nodes either generate or destroy links.

FL Computational Management ScienceThe interbank network
The large-scale structure of the interbank network changes drastically in times of crisis due to the effect of measures from central banks.

FCTK Journal of Computational Social ScienceModelling financial systemic risk
Complex networks model the links between financial institutions and how these channels can transition from diversifying to propagating risk.
Enhanced capital-asset pricing model for bipartite financial networks reconstruction
The challenge of statistical reconstruction is using the limited available information to predict stock holdings.
Non-linear distress propagation
Non-linear models of distress propagation in financial networks characterise key regimes where shocks are either amplified or suppressed.
Immunisation of systemic risk
Targeted immunisation policies limit distress propagation and prevent system-wide crises in financial networks according to sandpile models.
How the interbank market becomes systemically dangerous: an agent-based network model of financial distress propagation
We assess the fragility of the interbank lending market from 2004 to 2013
Reconstructing a credit network
New mathematical tools can help infer financial networks from partial data to understand the propagation of distress through the network.
