Research Interests
Fundamental Mechanisms of Radiation-Induced Deformation and Embrittlement, including modelling of radiation damage in reactor materials using both molecular dynamics and stochastic annealing method, defect formation and clustering, diffusion of interstitials and vacancies, interaction of point defects with dislocations, interfaces and segregation.
Atomistic simulations of materials properties, including modelling of fracture and crack propagation, simulations of interfacial defects in ceramics and intermetallic alloys, hydrogen embrittlement in hcp metals, phase transformation explored by molecular dynamics and modelling of the formation of nano-phase structures on surfaces.
