Christian Diem is a Senior Scientist in the Network Economics, Supply Chains & Financial Markets Group at the Complexity Science Hub. In his research, Christian aims to better understand economic and financial systems with tools from economics, network science, and agent-based computer simulations.

His focus lies on systemic risks and the propagation of economic shocks in supply networks and financial networks. Christian’s work ranges 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, and 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 contributed to projects funded by the Austrian National Bank (OeNB), the Austrian Research Promotion Agency (FFG), 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.
