We investigate the theoretical foundations of quantum theory, with a particular focus on the structure of quantum theory as an operational physical theory. The aim of our research is to formulate the principles of quantum mechanics precisely and improve our understanding of them, thereby enabling new experimental tests as well as applications in quantum technologies. Our work focuses in particular on the following topics:

• Features of quantum dynamics and quantum processes
• Correlations and axiomatization of composite quantum systems 
• Quantum measurements as a physical process
• Application of concepts from quantum information theory to new physical contexts
• Characterization of technological and fundamental quantum systems
