Research interests:
My research primary focuses on the plasticity of materials with heterogeneous microstructures that give rise to large spatiotemporal fluctuations during deformation. Of particular interest are metallic crystals where complex dislocation patterns form upon external load and deformation is characterised by power-law distributed strain bursts. I mostly perform theoretical investigations that are based on large-scale numerical simulations but I am also involved in experimental works related to micron-scale plasticity and methods used to characterise complex dislocation structures.
