Prof. Dr. Oana Cojocaru-Mirédin

Eva-Mayr-Stihl Chair for Cross-scale Material Characterization

Oana Cojocaru-Mirédin researches the design of energy materials with new functionalities.


Vision: To Re-Design energy materials via cross-scale characterization

What if the design of energy devices is done through a well-defined roadmap?

This will certainly accelerate the discovery of new energy materials so much needed as an answer to the energy crisis. Therefore, the goal of the group is to Re-Design energy materials with superior properties to makes them suitable for the use in energy conversion and storage in Germany and Europe. The Re-Design Strategy is fulfilled down to the Nanostructures level going from controlled synthesis to functions.

A big benefit of the group is the expertise in determining the composition and structure down to the atomic level. Even more, these can be cross-correlated with the functional properties. With that, we envision to determine an universal property map as a guide for reaching high-diversity of materials as found in nature and, finally, reaching devices with outstanding performances.


Focus: Development of green energy devices that exhibit outstanding performances through Re-Design of material properties down to the atomic level.
