Visiting Professor
T105 Chemistry and Materials
Visiting Professor

I am running my own group, the research group of Physical Electrochemistry and Electrochemical Physics (PhysElectrochemPhys), since September 2018. We focus on understanding how charge transfer takes place across solid-liquid interfaces, and within solid materials. Our current projects aim at developing next generation batteries for large scale energy storage.
