A theoretical physicist who, with Pilkyung Moon, calculated optical absorption in twisted bilayer graphene. Rotating one sheet changes the electronic electronic band structure and shifts absorption peaks associated with Van Hove singularities. Comparing a tight-binding model with a continuum model showed how an optical spectrum can identify the relative rotation of two atomically thin sheets.[ref]
