His primary responsibility is to collaborate with game developers to enhance image quality and graphics performance of their games; he is also a regular contributor at game developer conferences, such as GDC. Matthias's passion for computer gaming started at age 15 when he discovered that his school's Commodore PET 2001 computers could also play Black Jack. He started writing his own games soon thereafter and continues to use the latest graphics hardware to explore the limits of interactive real-time rendering. Before joining NVIDIA, Matthias was a game developer at GameFX/THQ. He received an M.Sc. in computer science from Brown University in 1990 and a B.Sc from Christian-Albrechts-University in Kiel, Germany, in 1987.
