Research topics from publications: Kekulé spiral order from strained topological heavy fermions. Representative work: The ground state of twisted bilayer graphene across much of its phase diagram is now understood to be the incommensurate Kekul\'e spiral (IKS). Using parent-state wavefunctions in the strained topological heavy-fermion model, the authors demonstrate here that the energetic stability of this state can be understood from ${C}_{2}$\ensuremath{\mathcal{T}}-protected non-Abelian Dirac node braiding. This gives a topological interpretation to the energetic favorability of the IKS
