Research
My research orients around questions with the following flavor: what is dark energy? What is the microscopic structure of space and time? Did space and time emerge in some kind of Big Bang? Will the universe end in a Big Crunch? What can we learn about quantum information from quantum gravity and black hole physics? How do we holographically define quantum gravity in spacetimes beyond anti-de Sitter space? What are the implications of symmetry, for example supersymmetry, in quantum field theory and effective theories of quantum gravity? What new theoretical structures exist between local quantum field theory and full-fledged string theory? What can gravitational wave observatories potentially teach us about quantum gravity and extra dimensions? What can string theory potentially teach us about collider physics and dark matter?
I also work on quantum field theory based approaches to non-equilibrium and nonreciprocal systems, which describe a broad range of phenomena found, for example, in active and soft matter systems, open quantum systems and models of neural networks. These disciplines are the primary focus of my research.
