All research have been related to the McStas Monte Carlo ray-tracing simulation package made for simulating neutron scattering instrumentation with the aim of expanding the use from design of instruments to use in connection with experiments. Such simulations can be used for planning experiments, decision-making during experiments and for understanding the collected data after the experiments.

Software projects
guide_bot: https://git.esss.dk/highness/guide_bot 
Python package for setting up and executing numerical optimization of neutron guides with simple user interface. Great for investigating and comparing large numbers of guide solutions for given or varied beam requirements. The previous MATLAB version of the software was heavily used in providing the information necessary for selecting the ESS Butterfly moderator.

McStas Union components: https://github.com/McStasMcXtrace/McCode 
Developed the Union components which were contributed to McStas. These allow modular scattering physics by combining an arbitrary number of scattering process into materials that can be used when specifying geometry of a scattering system. The geometry can be complex and nested, making it possible to simulate systems such as sample environments, filters and detectors where multiple scattering is highly relevant. Also includes flexible logging routines such that neutron scattering and absorption in the system can be visualized.

McStasScript: https://github.com/PaNOSC-ViNYL/McStasScript 
Python API for the McStas package, allowing users to write their instrument description directly in Python as well as running the simulation and working with the data.
