Om mig
A course on group theory in solid state physics and photonics together with a detailed description about the application of our Mathematica group theory package GTPack can be found in our book Group Theory in Solid State Physics and Photonics: Problem Solving with Mathematica. The book contains hands-on examples covering basic group theory to advanced applications.

Materials informatics and Organic Materials Database
We develop the Organic Materials Database - OMDB, transfering methodology from data science into functional materials research. The OMDB hosts, electronic, crystal, and magnetic structure information of more than 40,000 synthesized organic molecular crystals and metal organic frameworks. The data is accumulated through high throughput calculations. The OMDB is free. It hosts advanced pattern matching functionality and machine learning based property prediction tools.
The OMDB can be accessed via https://omdb.mathub.io.

Symmetry Principles of Quantum Matter
Quantum matter describes a class of phenomena where quantum effects remain dominant over a wide range of energy and length scales. The realization of quantum matter is typically strongly bound to symmetry, symmetry breaking, and topology. I apply and develop group theory based methodology to investigate quantum matter in the static and time domain, with particular focus on Dirac materials and superconductors.

Dirac Matter
Dirac matter describes phases of matter with elementary excitations behaving as Dirac fermions. I am interested in the realization and protection of Dirac states. Furthermore, I investigate applications of Dirac matter as well as interaction effects.
