Profile

Dr Thomas joined Queen Mary University in 2023 as a lecturer in quantum technology. He completed a MChem degree at the University of Oxford in 2011, and a PhD in nanophysics at the University of Bristol in 2016 with the Bristol Centre for Functional Nanomaterials.

Subsequently he was a postdoctoral researcher and then senior research fellow at the University of Oxford, in the Departments of Chemistry and Materials respectively, working on the synthesis and characterization of molecular electronic devices.  He is primarily interested in quantum transport and molecular electronics, i.e., studying electrical circuits in which a component, such as a transistor or switch, is a single molecule, with a view to applications in both classical and quantum computing, as well as sensing.

Research

Research Interests:

Dr Thomas’ research expertise is in quantum electronics, i.e., the fabrication of devices in which individual or self-assembled quantum objects, such as molecules, act as circuit elements. The aims of his research are to understand how the quantum (electronic/spin, vibrational) states of molecules and their dynamics (how they evolve in time) influence how they conduct electricity, and what new functionalities emerge when electronics are scaled down to nanometre dimensions. He is also interested in exploring wave-particle duality of electrons in two-dimensional materials, such as graphene, through the study of electronic interference effects, with a view to new sensing applications.
