Senior🎓
Top SchoolFabien Hermenier is a Senior Staff Member at Nutanix with 13 years of experience bridging academic research and production cloud systems, specializing in resource management and VM placement algorithms. On leave from his Associate Professor role at Université Nice Sophia Antipolis, he brings a researcher's rigor to large-scale engineering problems and has taught systems courses at Polytech Nice. His contributions to open-source—for example performance and memory-efficiency improvements in the choco-solver constraint programming library—reflect a pattern of optimizing core algorithms and test automation. Comfortable moving between prototypes on testbeds like Emulab and production cloud platforms, he combines deep algorithmic insight with pragmatic implementation. Based in Nice, he is known for turning complex scheduling and resource-allocation research into robust, deployable software.
