I am a theoretical condensed matter physicist. Condensed matter physics is

a rapidly evolving field of research driven by the potential for technological application as well as the quest for fundamental understanding of nature. The broad aim of my research is to study novel properties of strongly correlated quantum systems and to understand the interplay of interaction and disorder in many-body quantum dynamics and quantum entanglement.
