A seasoned generalist passionate about building a more resilient world that can better coexist with disasters. Currently contributing to the Joint-Exchange of Data and Information on Critical Infrastructure (JEDI-CI) project, a collaborative initiative under the Science and Technology Agreement between Sweden and the United States for Security and Resilience. His work focuses on understanding critical infrastructure interdependencies, enhancing preparedness, and boosting resilience against evolving multi-hazards and hybrid threats.

A technologist at heart with research experience and an interest in interdisciplinary research, focusing on:

• Systemic Risk and Resilience.
• Disaster Risk Governance.
• Modeling and Simulations.
• Decision Support Systems.
• Dynamic Decision Making Under Uncertainty.
• Impact Assessments & Risk Analysis of Natural Hazards.
• Application of Machine Learning and Artificial Intelligence for disaster risk management.
• Extreme Value Analysis and Anomaly Detection.
• Geographic Information Science (GIS) and Data Visualization.
• Database Administration, System Engineering and Scientific Programming.

As an avid explorer, when he’s not knee-deep in data or research, he’s likely:

• Hiking, camping and cycling.
• Playing sports and e-sports.
• Capturing life’s moments and extraordinary scenery.
