Gernot Heiser is professor for operating systems at the University of New South Wales (UNSW). He is also leader of the Embedded, Real-Time and Operating Systems (ERTOS) research program at NICTA. Recently he has founded a company called [Open Kernel Labs] (OK) where he serves as Chief Technology Officer.

His research focuses on microkernels and mikrokernel-based systems as well as virtual machines. His group produced the Mungi single address space operating system^[1] and implementations of the L4 microkernel that demonstrated the fastest inter-process communication ever reported on MIPS^[2], Itanium^[3] and ARM^[4] processors. On the XScale their Wombat, a virtualized Linux on the L4 microkernel, outperformed native Linux in context-switching benchmarks by up to a factor of 30.

In the past he also worked on semiconductor device simulation, where he pioneered the use of multi-dimensional modeling in the optimisation of silicon-based solar cells.
