Combining advanced electron microscopy, in-situ testing, and multiscale modelling to understand how crystalline defects govern the physical properties of materials.
Crystalline Defects & Physical Properties
No crystal is perfect. The tiny imperfections hidden inside metals and ceramics — called defects — are actually what control how strong, conductive, or brittle a material is. We study these defects to understand why materials behave the way they do, and ultimately how to make them better.
Micro-/Nano-structures: Understanding and Enhancing Material Properties
A material is not one crystal — it is millions of tiny grains packed together. How those grains are arranged, and how defects move between them, determines whether a part bends, breaks, or holds. We combine experiments and computer models to decode this complexity, from the nanometre to the real-world component.
Electron Microscopies
To see defects invisible to the naked eye, we use powerful electron microscopes. Our speciality is ECCI — a technique that lets us photograph individual atomic-scale defects inside a real, intact material, without cutting or destroying it.
