 Benjamin Klenk joined NVIDIA research in July 2017 after completing his PhD studies in Computer Engineering at the Ruprecht-Karls University in Heidelberg, Germany (defended with summa cum laude). His thesis focused on communication models for direct inter-GPU communication in which the GPU orchestrates the network traffic itself without the intervention of the CPU. He also holds a B.Eng. in Electrial Engineering from the Cooperative State Universtiy Mosbach, Germany and a M.Sc. in Computer Engineering from the Ruprecht-Karls University in Heidelberg, Germany.

Benjamin is a member of the Networking Research Group and his research focuses on networking architectures (switches & routers, network interfaces, etc.), communication models, and the acceleration of distributed and parallel applications.
