Reducing cost and time in materials development with atomistic simulations
“We contribute to the development of next-generation materials for energy conversion and storage applications using classical and quantum atomistic simulations coupled with continuum-level modeling and machine-learning techniques.”
We use quantum mechanical simulations for predicting properties of materials at the atomic scale. The properties are varied (conductivity, stability, reactivity, sensitivity, selectivity) and application specific (thermoelectrics, batteries, fuel cells, sensors). We perform a computational screening of candidate materials for the desired property and suggest promising candidates for experimental synthesis and characterization.

Interview with Georgy Samsonidze, Ph.D.
Lead Engineer Computational Materials Science
Please tell us what fascinates you most about research.
Finding myself in an altered state of mind when I become too much submerged into solving a complex technical problem. The introvert in me really enjoys these moments.
What makes research done at Bosch so special?
Continuous validation of our computational methods and tools through close collaboration with experimental teams. This is relatively rare in academia, where computational and experimental groups mostly interact through publications.
What research topics are you currently working on at Bosch?
Developing next-generation materials for sensors and fuel cells that will increase their performance and lifetime.
What are the biggest scientific challenges in your field of research?
The biggest challenges lie in understanding the structure–property relationships of materials. Currently, we have to screen materials databases, compute properties of each material, and select candidates with the desired properties for a specific application. This is computationally expensive and inefficient because of endless possibilities for new material structures. If we could invert the structure–property relationships, we would be able to directly obtain the structure of a material that has the desired properties.
How do the results of your research become part of solutions "Invented for life"?
We design and develop new materials that help to improve the quality, safety, and durability of future Bosch products, thus contributing to customer satisfaction and company success.
