About Nader Asnafi

Nader Asnafi, Professor in Mechanical Engineering, has a long industrial experience from Esselte Dymo, Sapa, Volvo Cars and Uddeholm. He has in more than thirty years

  • conducted market studies, business development, and product planning,
  • led research, development and advanced engineering to develop new sustainable products, processes and materials,
  • outlined and implemented business development plans, customer offers, management strategies and systems, product plans and product planning systems, production development, technology development and technology development systems, technology strategies, innovation strategies and systems, materials and production planning and control systems and capital rationalization, and
  • rolled out and implemented Lean product development and Lean manufacturing

both in Sweden and for Swedish companies internationally.

 

Nader has organized several international conferences and seminars.

 

Nader’s main focus area in research, development and education is Digitalized Development and Operation of Sustainable Products and Production/Manufacturing Systems. This includes product planning and realization, materials, product and production development, and manufacturing engineering and systems which are assisted by digitalization as means/tools and for which sustainability is at the focus.

Nader has more than 90 publications.
