I am an experienced academic (research and teaching), a Fellow of Higher education Academy (FHEA), UK, Professional Member of Institute of Materials, Minerals and Mining (IOM, UK), and certified Professional Engineer (PE) (equivalent to UK CEng) from Pakistan Engineering Council (PEC).

My PhD and MSc are from the University of Manchester, UK, and my BE in Mechanical Engineering is from NUST, Pakistan. I achieved Distinction in BE as well as in my MSc dissertation.

I worked as a Postdoctoral fellow on EPSRC funded research project at the University of Bath, Mitsubishi Heavy Industry funded project at the University of Cambridge and Ministry of Defence funded research project at the University of Manchester, UK.

I have won several grants, published extensively in high-impact journals. Presented my work in international conferences and contributed to edited books. I effectively work collaboratively with several international collaborators. I am a regular peer reviewer for many excellent journals in my research area and have acted as external examiner for PhD students.

I have experience teaching a wide range of modules related to materials, solid mechanics, stress and failure analysis, finite element methods and mechanics of composites and forensic engineering at all levels in HEIs. I believe in a student-centred teaching philosophy and have successfully experimented with blended learning approaches in recent years. I have supervised over four dozen student thesis and design projects. Lead mechanical department for engineering council accreditation of its BEng program. Lead teams in terms of executing funded projects and for organizing international conferences and carried out knowledge exchange and CPD activities.

Teaching responsibilities

I have taught a range of subjects in materials/mechanical engineering over the years. My current teaching responsibilities include teaching 'Advanced Engineering Materials and Applications', 'Materials and Manufacturing Processes', 'Failure Analysis' and 'Forensic Engineering failure analysis and prevention'

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 enhancement activities and have re-defined mechanical engineering programmes at NUST and CUST to bring them in line for the Washington accord accreditation.

Professional interests

I have been actively supervising research in the areas of sustainable composites. In particular as a key member of the composite materials research group of University of Derby, I have been actively supporting such SMEs directly and indirectly which are actively seeking ways to develop solutions that can help reduce carbon footprint across the supply chain for high carbon sectors such as transport and infrastructure. For example, in recent years one of our GROUPS KTP with a local SME lead to the development of a new low-carbon bio-based PFA resin system and this work is being further continued by two of our PhD students and several UG students.

Similarly, in another intervention, we supported a local SME in developing a solution for reducing embodied carbon from pre-cast concrete structures. Besides the local SMEs we are also actively working with our international partners such as Petronas University Malaysia, for developing innovative models for new recyclable thermoplastic composite materials.

Our students are the engine for this research and while carrying out these projects they become equipped with skills that will take them to the front of the queue in evolving job market. We are now at a stage where this research is being fed back into our graduate and undergraduate teaching programs as well as making our future graduates ready for facing this biggest challenge of 21st century.

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 falls under the following of five thematic areas.

  1. Progressive damage modelling in composites and composite joints using FE based as well as analytical methods
  2. Micromechanics 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:

FE based analysis of woven composites including:

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 (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 the 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 my 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. 

Supervised multiple student projects in collaboration with industry stakeholders, including Rolls Royce Apprentice Students, as well as those from other industries near Derby. In all these instances, students contributed positively, efficiently, and within budgetary and time constraints to on-going business activities.

International experience

I have worked in both Pakistan and Britain, and have carried out international collaborations on research projects in Malaysia, France, UAE, KSA and USA. Some of the universities that I worked in, followed the British system while others followed the US systems. My international accomplishments include: 

International Faculty Achievement Award (IAUP - NUST) 2014
Winner International Association of University Presidents (IAUP), International Faculty Achievement Award of NUST for the year 2014.

Project Lead for the British Council - DFID sponsored award under the DelPHE scheme titled, 'Capacity building for enhancing R&D in manufacturing, testing and certification of composite materials'

The project established a bilateral partnership between NUST department of Mechanical Engineering and National Composites Certification and Evaluation Facility at the University of Manchester, UK to improve capacity for carrying out high impact research in the area of composite materials with the long-term objective of contributing towards the attainment of millennium development goals of poverty reduction through industrial innovation. Thus, the key objective of the project was imparting training in design, manufacturing, testing and certification through workshops and seminars at three levels i.e. policymakers, academics and students.

It also aimed at enabling student/faculty exchange between NUST and Manchester through internship and guest researcher program.  A countrywide survey for requirements analysis for establishing R&D centre for composites manufacturing evaluation and certification was carried out as part of the project and report was presented to government and private industries during the Pakistan Composite Show and Policy Dialogue organised by PI as part of this project. The project resulted in introduction of new MSc/PhD level course in NUST curriculum, it increased awareness of the research and business potential for advanced composites and resulted in establishment of composites engineering research group.

Co-PI for the British Council - sponsored award under the InSPIRE - SPEKE scheme titled, 'Sustainable energy solution for rural communities through community participation'

The project built on the existing strategic partnership with British and Pakistani Universities (INSPIRE) by focusing on two new objectives. On one hand it aims at using the theoretical and lab results of the existing project to create a demonstrator unit with the help of local industry (Chitral engineering works) and installing this demonstrator on a canal in rural areas leased from the KPK/Punjab government. On the other hand it aims at increasing the acceptance of technology in the rural communities and motivating school and college students for getting science and technology education, and convincing them of the positive role technology can play in their lives.

In addition I have ongoing international collaborations with University Petronas Malaysia.
