Vasco is an Applications Engineer working especially in the fields of physical modeling and Control Design Automation. Before joining the Mathworks in 2016, Vasco worked at Liebherr Machines Bulle where he developed new control functions for different control units using Rapid Prototyping Systems and embedded code real time bypass. He was in charge and completely renew the company's library of physical models (from emission aftertreatment systems to diesel and gas engines) deployed to do real time HIL testing and embedded software validation. Vasco has a BSc as Mechanical Engineer (with participation in the Formula Student competition) and a Master degree in Energy Sciences and Technology, both of them obtained at the ETH Zurich.
