Our group investigates emergent phenomena in material systems with strongly interacting degrees of freedom, with a focus on complex layered chalcogenides. We are interested in discovering unexpected behaviour and properties that emerge when these layered materials are stacked in specific ways. We design and synthesize these layered systems, and probe their physical and chemical properties, ranging from multiferroicity, strongly correlated electronic phases to topological phases or catalysis, to expand fundamental understanding of these bottom-up created layered materials.

Our experimental approach is curiosity-driven and operates at the intersection of solid state physics, solid state chemistry, and nanoscience, employing techniques spanning transport and optical spectroscopy measurements, sulphur molecular beam epitaxy and single crystal growth, and nanoscale probe and device fabrication.

We combine our experimental work with computational simulations to elucidate the underlying mechanisms driving the stability of the layered structures and their behaviour. Through active feedback between experimental and theoretical methodologies, we aim to uncover fundamental physics while realizing emergent electronic and magnetic functionalities with practical technological applications.
