I'm a theoretical physicist interested broadly in quantum field theories and quantum lattice models with applications to condensed matter physics. The primary goals of my research are to understand better (1) what possible universal phenomena, phases, and phase transitions can emerge in quantum many-body systems and (2) how such emergent, macroscopic phenomena can depend on microscopic details. I am approaching these questions using various aspects of (generalized) symmetries and topology, and am currently working on:

(1) non-invertible symmetries in quantum spin models and their relationship to dualities.
(2) generalizations of the bulk boundary correspondence using the SymTFT and applications in classifying gapped and gapless phases of matter.
(3) the interplays between spacetime and internal symmetries (e.g., modulated symmetries, Lieb-Schultz-Mattis anomalies, and supersymmetry) and their effects on criticality.

More broadly, I am interested in

(1) All things topological phases of matter, from topological orders to SETs to SPTs.
(2) UV/IR mixing, both with and without fractons, and its relationship to foliated field theory and tensor gauge theory.
(3) Applications of tensor gauge theories to emergent gravity, elasticity and quantum melting, and symmetry-enriched topological orders.
(4) Quantum spin liquids and frustrated magnets.
(5) Applications of higher category and homotopy theory to physics.
(6) Applying ideas from quantum information theory to quantum lattice models and quantum field theory.

When I am not dreaming about physics and math, you can find me at the closest source of coffee, at the climbing gym dangling from a rope, or in the mosh pit of your nearest punk show (you should check out my favorite paper arXiv:1302.1886!).
