Advanced simulations and models are used to get to grips with complex problems. Research in theoretical modelling at LiU covers a very wide field. Researchers study everything from molecular motors and patient-specific drug treatments to processes in biological ecosystems and how the universe functions.

Theoretical modelling is becoming an increasingly important research area. Realistic simulations of complex systems can be used to supplement practical experiments, which are often both expensive and time-consuming. In some cases, mathematical models and simulations can completely replace experiments that may be dangerous, or experiments within geophysics and astrophysics that are extremely difficult or impossible to carry out.

New and exciting possibilities are now available to solve several important problems in a realistic way. Rapid developments in computer technology, efficient calculation algorithms, computer programs and databases filled with information give rise to an increased need for research and education in theory and modelling.

At LiU, research is carried out within bioinformatics, theoretical physics, theoretical chemistry, theoretical biology, and theory and modelling in organic electronics.

The National Supercomputer Centre (NSC) at Linköping University is also a provider of leading edge national supercomputing resources.

Sustainable nutrient and energy management

Natural resources are the building blocks of any eco system. Understanding where these resources are, how they flow on our landscapes, and why we see these use patterns are key questions to inform more sustainable management.

Mathematical Modelling of the Blood Circulatory System

Mathematical models of the circulatory system can be used in order to better understand the system and so help diagnose blood-vascular diseases and other problems while also enabling planning for the treatment of these diseases.

Nanoscale Engineering

Our vision is to generate knowledge that will trigger a paradigm shift with respect to the way contemporary materials are created.

AI helps researchers understand the machinery of cells

Breaking the code to understand why a protein takes on a specific shape has long been one of the major challenges in biology. A couple of years ago AI led to a breakthrough in this field. Björn Wallner’s research unites AI and bioinformatics.

Making stable molecules reactive with light

Researchers at LiU have used computer simulations to show that stable aromatic molecules can become reactive after absorbing light. The results may have applications in such areas as the storage of solar energy, pharmacology, and molecular machines.

Better wildlife observation with new counting method

Are wildlife populations increasing or decreasing? It is difficult to count wild animals, but the amount harvested through hunting gives an indication. Now, these statistics can be made more useful, thanks to a new model developed by researchers.
