Her research is in theoretical physics, with special emphasis on Quantum Theory of Computation, Information Theory, Thermodynamics, Condensed-Matter Physics and Quantum Biology. Some of her recent research has harnessed a recently proposed generalisation of the quantum theory of information –  Constructor Theory — to address issues at the foundations of the theory of control and causation in physics. These include applications to defining general principles encompassing classical, quantum and post-quantum theories of information; and to assessing the compatibility of essential features of living systems, such as the ability to self-reproduce and evolve, with fundamental laws of Physics, in particular with Quantum Physics. They also include the definition of a new class of witnesses of non-classicality in systems that need not obey quantum theory, such as gravity; and a scale-independent definition of irreversibility, work and heat, based on constructor-theoretic ideas.
