Interests
I am interested in the underlying algebraic structures of quantum theory, in particular how they pertain to possible post-quantum theories - those which exhibit phenomena beyond standard quantum mechanics. Such theories offer invaluable insight into how quantum theory manifests and how we might extend it in the future to capture unexplained phenomena.
Of particular interest is furthering our understanding of generalised decoherence structures including the transition from a post-quantum theory to quantum theory via a hyper-decoherence process. Some of my work involves studying classes of quantum-like theories which exhibit generalised decoherence structures and trying to understand the algebraic and operational characteristics of such theories.
