Biography

Ariyan gained a first BSc degree in Mechanical Engineering in 2009, a distinction Master degree in Mechanical Engineering Design from the University of Manchester in 2011 and awarded a PhD in Biomedical engineering involving finite element analysis (FEA) and Python programming to develop a computational wear algorithm from Liverpool John Moores University (LJMU).

Upon completion of his PhD, Ariyan joined Newcastle University as a finite element specialist (Postdoctoral Research Associate), responsible for undertaking wear analysis using FEA at artificial human joints until December 2016 and then he joined LJMU as a senior lecturer in Mechanical Engineering Design.

Ariyan’s primary areas of research are mainly in mechanical modelling and FE analysis (Static and Dynamic) with the development of advanced meshing, programming in FE environments, computational wear and fatigue algorithms, modelling of complex contacts, modelling of human joints using CT, MRI or point cloud data, modelling complex material properties as well as Fatigue testing, CMM measurement, Profilometry, Microscopy and Impact testing.

Research interest:
Finite element modelling and analysis for design and operations
Programming and scripting in FE environments
Development of computational wear and fatigue algorithms
Wear and fatigue testing
