Jonaitis, Reinhard Leprich and Dr. Houman Jafari, were named as General Managers. Houman was also named the CEO and Managing Director of VEC Imaging. In turn, Houman named Team Leads over the 5 focus areas of the business: Nanotube Technology, Nanotube Design, Electronics and Power Equipment, Tube Manufacturing and Business Operations.
