Hari is a Senior Lecturer in Biomedical Engineering at Swansea University. He did his undergraduate studies 2004-2008 in the Department of Mechanical Engineering at Imperial College London, where he also later completed his PhD titled "Blast loading of fibre reinforced polymer composite structures". He worked in the Mechanics of Materials Section and Soft Solids Group 2011-2013 as a postdoc, completing computational and experimental projects related to impact, nonlinear material behaviour and fracture.

In 2013, he was awarded a Research Fellowship funded by The Royal British Legion and Imperial College London to study Lung Mechanics in the Department of Bioengineering and The Centre for Blast Injury Studies. Here, he developed his research area focused on creating optimised protection strategies against injury, through characterisation of human body biomechanics in trauma.

His current research interests are focussed on lung mechanics. This involves both macro- and micro-scale evaluation of thoracic structural response to blast and impact. The aim of the research is to improve the understanding of underlying failure mechanisms occurring within the lungs to improve both the injury treatment and injury prevention. He is also studying new materials options and materials processing methods for improved energy dissipation in blast environments, which can be tuned to mitigate against a given injury mechanism or combination of mechanisms. At the Zienkiewicz Centre for Computational Engineering, he uses computationally-driven approaches to deliver targeted engineering solutions.

Other research interests include:

  • Full-scale explosive resilience evaluation of structures in air and underwater
  • Developing experimental models of blast injury
  • Surface and volumetric imaging techniques for structural characterisation and real-time diagnostics in dynamic loading environments
  • Development of novel experimental techniques and numerical models to optimise and evaluate the design of blast and ballistic resistant materials
  • Material characterisation and soft tissue behaviour: strain rate sensitivity, structural response in blast, failure modes and residual function post-blast
  • Development of macro- and micro-scale finite element models to predict deformation and fracture behaviour of various structural and biological materials under a range of strain conditions
  • Extension and validation of micromechanics analytical models for application in the design of composites and biomaterials
  • Development of biomimicking systems to study primarily lung physiology and provide replacement materials for research (3Rs)

Teaching

  • EG-232 Multivariable Calculus for Medical Engineers

    Module aims to build upon Engineering Analysis 1 and Engineering Analysis 2 to provide tools required for practical execution of mathematical operations. Application areas from image analysis to the characterisation flow fields, amongst others, will be studied in the context of this mathematical module. From transform functions to gradient operators, these mathematical tools will be studied in their fundamentals before being applied to biomedical application areas. This mathematics module aims to: provide further fundamental analysis tools for engineering applications; and provide a bridge towards advanced analytical modules in Year 2 and 3.

  • EG-268 Experimental Studies - Mechanical

    The course introduces the students to experimental studies in a wide range of subjects. There are four individual experiments (HEAT/JET/STRESS/VIBRATION) Each experiment is self contained and the student will be assessed via either: ¿ A lab report which will have a set of experiment specific questions to answer. ¿ An online Blackboard assessment All students work in groups and carry out four experiments, however the assessments are all individually submitted. The students keep a log-book of the experimental observations and results, which is used for reference for the technical report from each experiment written-up in the week after the experiment.
