Thomas Gazagnaire

Computer Scientist and Software Engineer.


I am the founder of Tarides, where we build secure, performant and resource-efficient network and storage services using MirageOS. Previously, I was engineer at Docker where I workded on Docker for Mac and Windows and I co-founded Unikernel Systems, where I was Chief Architect, to make unikernels easier to use so that they can be shipped and deployed everywhere. I also was Senior Research Associate at the University of Cambridge. Before that, I was CTO of OCamlPro, Principal Virtualisation Engineer at OnApp, and Senior Software Engineer at Citrix. I completed my Ph.D on distributed systems at Inria & IRISA in the DistribCom project and I obtained my Master and Bachelor degrees from ENS Lyon and ENS Rennes.

I am one of the main authors of the the MirageOS operating system library and the main developer of the Irmin Git-like distributed store. I previously designed and lead the implementation OPAM, the package manager for OCaml and I've worked on XenServer.


My interests primarily involve the application of formal methods and functional programming languages to complex-system engineering problems. More generally, I have a wide range of research and application interests including:

  • Cloud-computing;
  • Distributed and concurrent systems;
  • Verification (model-checking) of complex systems;
  • Automatic fault-diagnosis and monitoring of complex systems;
  • Application of functional programming to real-world problems;
  • Compilation and optimization techniques;
  • Partial-order theory.

I do most of my software developments in OCaml and my projects are hosted on GitHub.
