BIOGRAPHY

Dr. Ali Javili studied Mechanical Engineering at Sharif University of Technology in Tehran, Iran and then moved to Germany for his graduate studies. He received his M.Sc. in Computational Engineering from Bochum University in 2007 followed by his PhD in Mechanical Engineering at the University of Erlangen-Nuremberg in 2012. From 2013, Dr. Javili worked on magneto-mechanical modeling of materials at the University of Erlangen-Nuremberg and consequently, moved to the Computational Micromechanics of Materials Lab at Stanford University until the end of 2015 as a post-doctoral research fellow. Prior to joining Bilkent, he was a senior researcher in the institute of mechanics at TU-Dortmund from 2016. His current research revolves around computational multi-physics multi-scale understanding of complex materials behavior where lower-dimensional energetics and higher-order ansatzes play a crucial role.

RESEARCH

The majority of my research applies to computational simulations of materials from the perspective of continuum mechanics. During the past years, I have developed my own efficient finite element code capable of modeling the material response under a broad variety of loading conditions and at different scales specially in challenging coupled problems with intrinsic instabilities. This fairly advanced and highly flexible finite element code allows me to readily examine the theory and it is often extremely useful to better understand and explain the physics of complex phenomena. In particular, I am interested in formulating surfaces, interfaces and curves, overall referred to as lower-dimensional energetics, from theoretical, mathematical and numerical aspects. Such theories are becoming increasingly important when modeling the response of materials at smaller scales and notably, at the nanoscale due to the increasing area to volume ratio. Lower-dimensional energetics can be viewed as the intrinsic structures of higher-gradient theories explaining the scale effect in continuum mechanics and hence, of crucial importance in general.

My research interests are:
 - Computational continuum mechanics
 - Interfaces and interphases
 - Instability analysis across the scales 
 - Nano-mechanics
 - Fracture mechanics
 - Surface elasticity theory
 - Multi-scale formulation and homogenization
 - Multi-physics
 - Bio-mechanics
 - Smart materials
 - Metamaterials
 - Peridynamics
 - Applied mathematics
