I’m a postdoc researcher at DTU Compute & the Copenhagen Center for Social Data Science (SODAS) and a part of the Nordic Pandemic Preparedness Modelling Network. I’m curious about questions that cut across disciplines and everyday life, especially those that can improve public health and bridge theory and practice. I use data to understand social behavior and build citizen-driven solutions to tackle epidemiological challenges. I have a background in physics of complex systems and hold a D.Sc. in computer science from Aalto University. As a writer and editor-in-chief of sitpor.org (FA), I also stay deeply involved in science communication. You can read more about me here.

Marco Polo describes a bridge, stone by stone.
“But which is the stone that supports the bridge?” Kublai Khan asks.
“The bridge is not supported by one stone or another,” Marco answers, “but by the line of the arch that they form.”
Kublai Khan remains silent, reflecting. Then he adds: “Why do you speak to me of the stones? It is only the arch that matters to me.”
Polo answers: “Without stones there is no arch.”
Invisible Cities, Italo Calvino
