Bio

Volkmar Uhlig joined IBM T.J. Watson Research Center as a research staff member in 2005. He is member of Project Kittyhawk which investigates the feasibility of a global-scale computer system capable of hosting the Internet. As part of this project he was leading the systems work applying Blue Gene's supercomputer capabilities to real-time stream-based data analysis for the financial industry (IBM press release, Forbes).

Prior to the current work, Mr. Uhlig worked on system and device virtualization. He held an R&D position at University of Karlsruhe. In Karlsruhe he was one of the prime architects of the L4Ka::Pistachio microkernel; the commercialized version of Pistachio by Open Kernel Labs runs on millions of cell phones. His research included multiprocessor scalability, virtualization, and multi-server systems. As part of his graduate program he worked at Intel Research and IBM Watson Research.

Mr. Uhlig holds a Ph.D. in Computer Science from University of Karlsruhe and a M.Sc. from Dresden University.
