'With my research, I can truly make a difference for our country'
Researcher Loe Schlicher knows better than anyone how collaboration with security organizations works. Using game theory, he supports various national safety institutions — including the Dutch police, the National Coordinator for Counterterrorism and Security (NCTV), and the Ministry of Defense.
Since 2018, Schlicher has been working with several organizations responsible for keeping the Netherlands safe. His research relies heavily on game theory.
“This method allows us to explicitly include and model the strategic behavior of an opponent,” Schlicher explains. “It helps us make tactical and operational decisions that won’t play into an adversary’s hands.”
Better protection and surveillance
For the Stelsel Bewaken en Beveiligen (the national protection and security system), he studies how to better protect individuals and locations that might be targets of threats. These include lawyers, scientists, diplomats, journalists, politicians, and judges — as well as government buildings, religious sites, and educational institutions.
The system is a collaboration between the Dutch police, the Royal Netherlands Marechaussee, the NCTV, the Public Prosecutor’s Office, and the General Intelligence and Security Service (AIVD).
One of Schlicher’s PhD candidates, Sven de Ronde, is studying how to patrol more effectively — and less predictably — in cities such as The Hague, where embassies, ministries, and the Dutch Parliament are all located close together.
“Patrol routes shouldn’t become too predictable, because adversaries could take advantage of that,” says Schlicher.
A practical tool
Using game theory, the team builds models that help make patrol routes unpredictable. “We started with two or three locations and one vehicle, so we could fully understand the model,” Schlicher explains. “Only then do we scale up to more complexity.”
“It’s hard to predict what challenges we’ll face as we expand the model. But it would be fantastic if, four years from now, we have a decision-support tool that helps patrol officers move around unpredictably. Time will tell if that’s possible.”
Smarter logistics in mission areas
Together with his colleague Rob Basten, Schlicher is also involved in a project funded by the European Defence Fund (EDF) that aims to make logistics chains in mission areas more efficient. One of the questions they explore is whether 3D printing could help by allowing spare parts for military vehicles to be produced on-site.
“We’re working with partners from several European countries — including France, Denmark, and Spain,” says Schlicher. “Our partners focus on the technical side: how to print advanced components. We, in turn, look at how to integrate those components into the logistics chain. It’s exciting to see these two worlds come together.”
A sense of purpose
“The research I do in the field of national security helps make surveillance smarter and protection systems stronger — so people can live and work safely,” Schlicher says. “That way, I can truly make a difference for our country. That gives me a great sense of purpose.”
