Dr. Gérald Oster
Associate Professor at TELECOM Nancy / Université de Lorraine
Researcher in the COAST Team / LORIA–Inria Nancy-Grand Est
Gérald Oster is an Associate Professor at TELECOM Nancy, University of Lorraine since 2006. He is a member of the Inria Coast project-team. He has an expertise in distributed collaborative systems with a focus on content replication mechanisms and their applicability. He received his Ph.D. in Computer Science from Nancy University in 2005. During his Ph.D., he worked on verification of correctness of a family of optimistic replication mechanisms (operational transformation) dedicated to collaborative editing. He proposed a framework based on an automated theorem prover and several sets of verified transformation functions for multiple data types. He worked on the design and the implementation of a universal file synchronizer. He is one of the pioneers of the CRDT approach as he participated in the design of the WOOT algorithm that initiated researches on these distinctive data structures. He is currently investigating the limitations and the applicability in diverse domains of these novel replicated data structures. Gérald is or was involved in several research projects and participated in several technologies transfer-oriented projects.
