Gernot Heiser (born 1957) is the John Lions 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 Labs) where he serves as Chief Technology Officer.

Research
Heiser's research focuses on microkernels and microkernel-based systemsas well as virtual machines, with a specific emphasis on performanceand reliability.
His group produced the Mungi single address space operating system,[1]aimed at clusters of 64-bit computers, andimplementations of the L4 microkernel with very fast inter-process communication.[2] His Gelato@UNSW team was a foundingmember of the Gelato Federation, and focused on performance andscalability of Linux on Itanium. They established theoretical andpractical performance limits of message-passing IPC on Itanium.[3]
Since joining NICTA at its creation in 2002, his research shiftedaway from high-end computing platforms towards embedded systems, withthe specific aim of improving security, safety andreliability via the use of microkernel technology.[4]This lead to the development of a new microkernel calledseL4, and itsformal verification,claimed to be the first-ever complete proof of the functionalcorrectness of a general-purpose OS kernel.[5]
His work on virtualization was motivated by the need to provide acomplete OS environment on his microkernels. His Wombat projectfollowed the approach taken with theL4Linux project atDresden, but was amulti-architecture paravirtualized Linuxrunning on x86, ARM and MIPS hardware. The Wombat work later formed the basis for the OKL4 hypervisor of his company Open Kernel Labs.
The desire to reduce the engineering effort of paravirtualizationlead to the development ofthe soft layering approach of automated paravirtulization whichwas demonstrated on x86 and Itanium hardware.[6]His vNUMA work demonstrated a hypervisor which presents a distributed system as ashared-memory multiprocessor as a possible model for many-core chipswith large numbers of processor cores.[7]
Device drivers are another focus of his work, including the firstdemonstration of user-mode drivers with a performance overhead of lessthan 10%,[8]an approach to driver development that eliminates the majority oftypical driver bugs by design,[9]and a demonstration of the feasibility of the automatic generation ofdevice drivers from formal specifications.[10]Recent research also includes power management.[11]
In the past he also worked on semiconductor device simulation,where he pioneered the use of multi-dimensional modeling in theoptimisation of silicon-based solar cells.[12]
