I am broadly interested in quantum gravity, particularly in the context of holography. AdS/CFT provides a concrete paradigm in which to investigate such questions as the emergence of spacetime from quantum entanglement, the reconstruction of black hole interiors, and the localization of information in gravitational theories.
One focus of my current research is holographic complexity, which is conjectured to encode dynamical information about the interior of the Einstein-Rosen bridge that joins two entangled black holes. In this sense, complexity allows one to probe beyond the holographic shadows elucidated by my previous research, which pose barriers to existing bulk reconstruction schemes. Additionally, some of our group's recent work demonstrates that complexity contains information to which entanglement entropy is insensitive, and hence represents a novel probe of dynamical quantum systems.
I am also interested in applying ideas from algebraic quantum field theory (AQFT), notably Tomita-Takesaki modular theory, to these and other fundamental questions. For example, my latest work applies this framework to the study of black hole interiors, and demonstrates that state dependence is an inevitable feature of any attempt to represent information behind horizons, with potential implications for locality and emergent spacetime. Modular techniques also show promise for studying notoriously thorny questions of entanglement in quantum field theory, such as those which underlie the firewall paradox, or the factorization of gauge or gravitational theories.
My publications in high-energy physics can be found on INSPIRE, or by following the links on my ORCID profile.
I did my PhD with Ben Freivogel at the University of Amsterdam, where I primarily focused on various aspects of bulk reconstruction, as well as the black hole information or firewall paradox. I spent eight months at the Perimeter Institute as a visiting graduate fellow, during which Rob Myers and I developed a first concrete definition for complexity in field theory in the context of the holographic proposal mentioned above. I am currently a member of the independent research group Gravity, Quantum Fields and Information (GQFI) led by Michal Heller, where I continue to study questions at the intersection of quantum gravity, quantum field theory, and quantum information.
