Mathematics paving the way for smarter designs
2026-09-01I juni disputerade Mario Setta vid Karlstads universitet med sin doktorsavhandling i matematik: Boundary-Aware and Multiscale Methods for Topology Optimization. Hans forskning handlar om att utveckla och förbättra metoder för topologioptimering.
What is topology and why did you choose this topic?
"My thesis focuses on how topology optimization can be improved, that is how computers can be used to find an optimal shape for a structure so that it is as efficient as possible while using as little material as possible. Among other things, I investigated how to account for very small details and different material layers. This is becoming increasingly important as technical products become smaller and as advanced shapes can be manufactured using 3D printing, where objects are built layer by layer."
Which results or conclusions from your research do you consider the most significant?
"I am particularly proud of two parts of my research. The first is a new method for better controlling the boundaries and sizes of different parts of a structure. The second concerns heat. I developed a method that makes it possible to better account for how heat behaves in microscopic structures. In the future, this could make it easier to create more efficient and advanced technical solutions."
What challenges did you encounter during the research process, and how did you deal with them?
"One of the biggest challenges was getting the mathematics and computer calculations to work together. As a PhD student, I also had to learn how to deal with uncertainty and setbacks. For a period, I spent a long time working on ideas that did not produce the results I had hoped for. I therefore had to change direction, which was difficult after investing so much time in the work. I learned that research is often about trial and error. By breaking the problems down into smaller parts and discussing them with my supervisor and colleagues, I was able to move forward. I also learned that sometimes it is just as important to know when to change direction as it is to find the right solution."
How does your thesis contribute to the research field or to society from a broader perspective?
"My research makes it possible to better tailor technical structures to their function and materials. In the long term, this could contribute to lighter, more efficient, and more reliable products, including in 3D printing, thermal engineering, and the development of new materials."
