Christian Diem is a Marie Skłodowska-Curie Actions (MSCA) Postdoctoral Fellow at INET Oxford and the Smith School for Enterprise and the Environment, where he studies how shocks in firm-level production networks spread and how these insights can enhance economic simulation models.

Before taking on this role, Christian was a Senior Scientist in the Network Economics, Supply Chains & Financial Markets Group at the Complexity Science Hub until September 2024. His research at CSH focused on deepening the understanding of economic and financial systems using a combination of economics, network science, and agent-based simulations.

Christian’s expertise centers on systemic risks and the ripple effects of economic shocks in supply and financial networks. His work spans from optimally rewiring interbank networks to reduce systemic risk, quantifying systemic risk in large-scale firm-level supply networks, reconstructing the Austrian food supply chain network, to extending financial stress testing to include supply chain effects. He is one of the main organizers of a new workshop series focusing on firm-level supply networks (https://firmnets2024.csh.ac.at).

He acquired and contributed to projects funded by the Austrian Research Promotion Agency (FFG), the Austrian National Bank (OeNB), and the Vienna Science and Technology Fund (WWTF). Christian holds a master’s degree in Quantitative Finance and a PhD in Economics and Social Sciences, both from the Vienna University of Economics and Business.
