Orran Krieger

Orran Krieger is a Professor in the Department of Computer Science at Boston University's College of Engineering with a distinguished research career spanning over three decades. His work has significantly influenced the fields of operating systems, virtualization, and cloud computing, with publications in top-tier venues including OSDI, EuroSys, and USENIX ATC.

Krieger's research interests focus on operating system design, virtualization technologies, cloud infrastructure, resource management, and performance optimization. His early work on the HFS file system and NUMAchine multiprocessor laid foundational work in system architecture, while his more recent research addresses contemporary challenges in cloud computing, unikernels, and energy-efficient network applications. His research consistently bridges theoretical insights with practical system implementations.

Analysis of Krieger's recent publications reveals a strong focus on cloud-native technologies, particularly unikernels, resource isolation techniques, and performance-energy tradeoffs in network applications. His work demonstrates a consistent evolution from traditional operating system concerns to modern cloud infrastructure challenges, with particular emphasis on security, performance optimization, and resource management in distributed environments. The collaborative nature of his work is evident through numerous co-authorships across institutions.

Krieger has mentored numerous researchers who have become prominent in the systems community, including Jonathan Appavoo, Dilma Da Silva, and Peter Desnoyers. His leadership in projects like the Open Cloud Testbed demonstrates his commitment to creating research infrastructure for the broader community. His work has been supported by significant research grants focused on cloud infrastructure and operating system innovation.

As a key contributor to the K42 operating system project and more recently to the Open Cloud Testbed initiative, Krieger has helped establish research platforms that have enabled significant advances in operating system research and cloud computing. His ongoing research continues to address fundamental challenges in system architecture for modern computing environments.
