After obtaining degrees in Mechanical Engineering in the UK and Aerospace Engineering at the University of Washington, Seattle, Nader worked on CFD code development at Imperial College in London. In 1989 he moved to Germany to join the company INVENT as a CFD specialist, and in 1991 joined Computational Dynamics (subsequently CD-adapco, now part of Siemens), setting up their German office in Nuremberg, and, in 1997, their Italian office in Bologna. Although focusing on business development for CD’s STAR-CD software, his responsibilities ranged from sales to technical support, training and project work. In 2003 Nader started working with ESTECO and, together with Carlo Poloni, set up ESTECO North America Inc., with the responsibility of selling and supporting ESTECO Technology in North and South America, and, subsequently, in India.
