Mads-Peter Verner Christensen

In his PhD studies Mads-Peter has studied global optimization methods for use with atomistic systems. In nature materials often occur in the energetically most favourable configuration, with quantum mechanics providing a way of calculating that energy, which allows computer simulations to be used to predict the structure of materials at the atomic level - which is the first step towards predicting the properties of new materials. However, this is a difficult optimization problem with an enormous number of possible solutions, therefore advanced methods are required in order to find the correct solution, which machine learning methods can help with.

These methods can learn using data collected on the fly and use that learned knowledge to help guide the optimization process.
The PhD study was completed at Department of Physics and Astronomy, Faculty of Natural Sciences, Aarhus University.
