Research

We explore and engineer optically addressable spin defects in solid-state materials, with a focus on discovering and understanding new platforms. In particular, we investigate defects in wide-bandgap and van der Waals materials such as hexagonal boron nitride (hBN), which offer opportunities for atomically thin quantum sensors. Our work combines materials engineering with studies of the underlying photo- and spin-physics, and evaluates the potential of these systems for nanoscale quantum sensing. 

We develop and apply solid-state spin systems — most notably the nitrogen-vacancy (NV) centre in diamond — as precision quantum sensors of magnetic and electromagnetic phenomena. A key focus is the design and implementation of complete sensing instruments, including magnetic microscopes and platforms for remote detection. We aim to translate these technologies beyond the laboratory, targeting practical and deployable solutions for applications in advanced materials (e.g. van der Waals magnets), electronics, and related fields. 

We develop fluorescent nanomaterials as versatile probes for biological sensing and imaging. These systems — including quantum dots, carbon-based nanomaterials, and fluorescent nanodiamonds — offer high brightness, photostability, and tunable optical properties. By tailoring their surface chemistry and biofunctionalisation, we design nanosensors capable of probing biochemical and physical processes in complex biological environments, with applications in bioimaging and diagnostics. 

We investigate spin-dependent and magnetic effects in molecular and fluorescent systems, including genetically engineered proteins and organically derived carbon nanomaterials. Our work focuses on understanding the interplay between spin physics and optical emission (spin photophysics) in these systems. We also explore their potential as nanoscale sensors operating in aqueous and biological environments, bridging quantum sensing concepts with soft and bio-compatible materials.
