I have a Professional Engineer (Mechanical) status from Pakistan Engineering Council which is similar in level to CEng qualification of UK. I also have Institute of Materials (IOM), UK, ProfGradIMMM status. Highlights of my career include:

Teaching responsibilities

I have taught a range of subjects in materials/mechanical engineerining over the years. My current teaching repsonsibilities includes teaching 'Advanced Engineering Materials and Applications' and 'Materials and Maufacturing Processes'. In the past I have taught courses including 'Finite Element Analysis of Composites', 'Mechanics of Composites', 'Finite Element Method', 'Mechanics of Materials I' (solid mechanics 1), 'Mechanics of Materials II' (solid mechanics II' and 'Design of Machine Elements'.

I have also been involved in teaching quality enhahncement activities and have re-defined mechanical engineering programmes at NUST and CUST to bring them in line for the washington accord accredation.

Professional interests

I have been involved with various professional academic activities such as 

Research interests

I have a rich and diverse research profile. In the start of my career my research focused on FE modelling and testing of woven composite’s lap joints subjected to impact loading. Later, I expanded my research portfolio in both depth and breadth. Thus, currently my research and research supervisions fall under following five thematic areas.

  1. Progressive damage modelling in composites and composite joints using FE based as well as analytical methods
  2. Micro-mechanics of composites and multiscale modelling (both FE and analytical modelling)
  3. Software development for composites research, teaching and analysis
  4. Development of Composite testing standards, methods and equipment.
  5. Composites manufacturing and product design.

Because of my research experience, I boast the following key research skills:

Experience in industry

Effective research collaboration and partnership with industry underpins success for academics. My experience of collaborative research and industrial engagement is at various levels. For example, my Post-Doctoral experience at all three Universities where I carried out research (i.e. The University of Bath, The University of Cambridge and The University of Manchester was on projects that were heavily sponsored through the industries. For example the Cambridge project was funded by Mitsubishi Heavy Industries (MHI), Japan and the Manchester project was funded by Ministry of Defence (MOD), UK, respectively. The project at Bath was an EPSRC project however it also involved GKN and Airbus as industrial partners. As part of the project at Cambridge I was involved in direct discussions and reporting to MHI on project deliverables while the work in Manchester required me to report my findings to MOD and Nanoforce. In addition, during the period of Post Doc in Manchester I also performed contract work on behalf of NCCEF, University of Manchester for industry clients such as Brook House for X-ray CT work. 

Several of my undergrad and postgrad projects have been completed with active partnership and help from local industries. As for example the three MSc projects related to developing testing standards of composites required active collaboration with our colleagues at NESCOM for completion. Another MSc thesis titled ‘Enhancement of mechanical properties of woven glass epoxy composites using aligned multiwall carbon nanotubes’ supervised by me, was based on the requirements posed by our industrial partner in a public sector aerospace manufacturing setup (AWC, NESCOM). In this project we worked on a novel method of using magnetic field for alignment of carbon nanotubes during vacuum assisted resin infusion. Another example of collaborative project supervision includes supervision of two projects funded by heavy industries Taxila, for development of high speed impact testing facility for body armour materials. In a similar manner my supervised BE project titled, ‘Indigenous development of pre-preg manufacturing machine for Uni-directional composites’ is a result of my interaction with the hockey stick manufacturers association of Pakistan and in Particular with Grays of Cambridge, who are the largest exporters of hockey sticks from Pakistan and extensively use in-house produced pre-preg for the production of their hockey sticks. While reading the above examples, it must be kept in mind that all these projects have been completed with industry support in a third world country (developing country) where the culture of academic / industry collaboration is very less developed.
