We work on research projects that aim at an accelerated materials design at BAM and the University of Jena. We primarily focus on the safety and sustainability of materials. Together with our colleagues at BAM, we aim at combining our efforts with [Materials Acceleration Platforms](https://www.bam.de/Navigation/EN/Topics/Materials/Materials-design/materials-design.html) (i.e., automated platforms for materials searches/optimizations). Additionally, [chemically complex materials](https://www.bam.de/Navigation/EN/Topics/Materials/Materials-design/materials-design.html) are one of our joint interests with colleagues at BAM.

#### New chemical heuristics

The group works to test and develop chemical heuristics (intuitive rules) to advance knowledge and understanding in solid-state chemistry and physics, using geometric and quantum chemical descriptors for chemical environments. For the latter, the group is developing open-source tools for automated bond analysis ([LobsterPy](https://github.com/JaGeo/LobsterPy), [atomate2](https://github.com/materialsproject/atomate2))

#### High-throughput calculations and automations

Large amounts of reliably calculated material data are necessary to develop new chemical heuristics. Here, the group develops workflows and methods for high-throughput calculations to reliably perform such calculations. Among other things, the group regularly contributes its own developments to well-known open-source material informatics codes such as [Pymatgen](https://github.com/materialsproject/pymatgen), and [Atomate2](https://github.com/materialsproject/atomate2) and has extensive expertise with these codes. Because of these activities, Janine is part of the [Materials Project Software Foundation](https://next-gen.materialsproject.org/about/people).

#### Machine Learning Potentials

Together with our collaboration partners (group of [Prof. Volker Deringer](https://www.chem.ox.ac.uk/people/volker-deringer)) at the University of Oxford, we develop the software [autoplex](https://github.com/autoatml/autoplex) to automate the training and evaluation of machine learned interatomic potentials. Together with the group of [Prof. Silvana Botti](https://www.physik.ruhr-uni-bochum.de/Professuren/prof-dr-botti-silvana/) at Ruhr University Bochum, we work on finding new chemically complex oxides.

#### Vibrational Properties

Vibration properties play a fundamental role in the stability and heat transport of materials. Both material properties are significant for the safe use of materials. Here, the group is concerned with the ab initio prediction of such data to advance machine learning of such properties.
We accelerate materials design with computational and data-driven approaches at BAM and the University of Jena. In particular, we focus on the design of safe, sustainable, and reliable materials. To achieve this, we combine first-principles simulations, condensed matter physics, materials informatics, machine learning, and high-throughput computational methods.

Our research is organized around two complementary themes: (i) materials discovery with Materials Acceleration Platforms and (ii) machine-learned models for realistic materials simulations of advanced and chemically complex materials. In particular, we are interested in battery materials. These activities are supported by substantial contributions to open-source software and community research infrastructures. The research connects to the activity fields [Materials Design](https://www.bam.de/Navigation/EN/Topics/Materials/Materials-design/materials-design.html) and [Electrical energy storage and conversion](https://bam.de/en/topics/energy/electrical-energy-storage) at BAM and includes collaborations with researchers across both areas.
