About

Overview

Dr Sathiskumar Anusuya Ponnusami works as a Lecturer in Structural Mechanics in the Department of Mechanical Engineering and Aeronautics at City, University of London. Prior to City, he worked as a Postdoctoral Researcher in Solid Mechanics and Materials Engineering at the University of Oxford, where he also continues to be a visiting academic.

He completed his PhD from Delft University of Technology (TU Delft) in the Netherlands. His doctoral research centered around computational modelling of fracture and healing in self-healing turbine composite coatings for aerospace applications supported by collaborative experimental development with material scientists. He also served as the leader of the team MultiFun, that won the £ 30,000 Airbus-UNESCO Fly Your Ideas Global Challenge 2015. He is also the awardee of the NLF Dutch Aerospace Award 2015 (University category, Netherlands), ITMA Future Materials Awards 2015 (WTiN, UK) and ICSHM Young Scientist Award 2013.

Some of his current research topics include:
* Integrated numerical modelling and experimentation of failure in composite/heterogeneous materials
* Application of data science and machine learning techniques to solid mechanics problems
* Multiscale homogenisation and failure prediction.
* Modelling of Self-healing materials
* Reduced-order structural models

His main teaching activities cover subjects such as structural analysis, finite element method and composites.
