Äbbas Karimi Rizi

Äbbas Karimi Rizi is a Postdoctoral Researcher at DTU Compute and Copenhagen Center for Social Data Science (SODAS), with a Doctoral Researcher background at Aalto University's Department of Computer Science. He is a member of the Nordic Pandemic Preparedness Modelling Network and contributes to research on epidemic interventions and temporal networks.

• Affiliations: DTU Compute, SODAS, CX Aalto
• Academic Rank: Researcher

Research Interests:
His work bridges network science, epidemiology, and computational modeling to study spreading phenomena in social networks. Key areas include modeling pharmaceutical and non-pharmaceutical interventions for epidemics, analyzing the impact of vaccination homophily on herd immunity, and exploring temporal network structures through non-equilibrium phase transitions. He also investigates signed networks and balance theory from his earlier physics background.

Recent Publications:
Karimi Rizi's research focuses on epidemic thresholds, contact tracing, and network geometry. His 2025 PNAS article examines herd immunity's spatial dynamics, while 2024 works in Physical Review E and arXiv explore clique-based contact tracing and cross-group homophily effects.
