About

I am a theoretical physicist working at the interface of quantum foundations, quantum gravity, and cosmology, with a particular interest in how spacetime and subsystem structure may emerge from quantum theory. My work combines tools from quantum information, quantum field theory, and philosophy of physics to study questions about locality, entanglement, reference frames, and the status of spacetime in fundamental physics. I am also interested in connecting these foundational questions to cosmology and possible observational signatures.

I am also one of the founders and organizer of ScientiFika (https://scientifika.se/).
