  4. 4. Dimensional Control Systems | 2017 All Rights Reserved Presenters Matthew Shaxted, Founder and President of Parallel Works, has led innovation efforts within several large world-class architecture / engineering organizations, working at the intersection of parallel computation, design and the built environment. Matthew now spends much of his time interacting with Parallel Works customers in the built environment and manufacturing verticals, helping them unlock the powers of high-performance computing in their business practices. D.J. Gray, Product Engineering Specialist, has been working at Magna Seating for 18 years in various engineering roles. In his current role as a DFSS Master Black Belt he works on design, analysis, and optimization of structural products and mechanisms in addition to training and mentoring DFSS. In his spare time he enjoys building complex 3DCS models. Eric Kaphengst, Software Developer at Dimensional Control Systems, has been working at DCS for 5 years. He graduated from Michigan Technological University with a degree in physics.
