I am a researcher in Computer Science; my research topic is distributed
systems (i.e., interconnected computers working together).
My two current projects are:
- Understanding replication and
Replication is an essential feature of a distributed system, but
updates cause the issue of consistency between replicas.
Strong consistency is easy to understand but expensive (and
impossible if there are failures); weaker models are complex.
Rather than pre-defined consistency models, we propose a “Just-Right
Consistency” approach, tailoring the consistency protocol to
specific application requirements, and using static verification to
ensure that the application remains correct.
- Concurrent programming.
Programming concurrent programs with shared memory is incredibly
bug-prone, yet (with multi-core processors) increasingly relevant.
Fine-grain concurrency is especially challenging.
I am particularly interested in garbage collection for managed
runtime environments on large-scale many-core computers.
This is related to my previous work on distributed garbage collection.
I work for Inria, the French National Institute for
Computer Science and Control Science.
I am part of Regal, a joint group
between Inria and LIP6 (the Computer
Science laboratory of Université Paris-VI
Pierre-et-Marie-Curie) in Paris.
I previously led the Cambridge
Distributed Systems Group (Camdis)
at Microsoft Research
Cambridge (MSRC), from October 1998 to March 2005.
For several years before that I was the leader of Inria's SOR (Systèmes d'objets
répartis, Distributed Object Systems)
I am a member of the board of Société
Informatique de France, the French learned society in Informatics.
I am past member of the ACM Europe
I am the past chair of EuroSys, the European professional society
in Computer Systems, which I was instrumental in creating.
(EuroSys is is the European chapter of SIGOPS.)
Marc Shapiro is a Principal
Researcher (DR1) in the Regal
group of UPMC-LIP6 and Inria.
His research topics concern distributed computer systems, data
replication and consistency algorithms, and multicore algorithms. He
leads the SyncFree European
project for highly-available cloud computing and storage, developing the
He is the co-inventor of Conflict-free
Replicated Data Types (CRDTs) designed to reconcile availability and
He invented the proxy concept,
which is now universal on the Internet.
Dr Shapiro's career started with a PhD in Toulouse (U. Paul Sabatier and
LAAS), followed by a post-doc at MIT, research positions at CMIRH and Inria, and a
sabbatical at Cornell.
He is an author of 100
international publications, some in the most prestigious venues, 18
recognised software systems, and five patents.
He led the Cambridge Distributed Systems group at Microsoft
Research Cambridge (UK) for six years.
Dr. Shapiro, a Senior Member
of the ACM, is known for his dedication to
organising the Informatics community and making its voice heard in
He has been a member of several Program Commitees in operating systems,
distributed systems, persistent systems, and garbage collection.
Recent examples include:
Ongoing research grants and collaborative projects:
(French) ANR Project RainbowFS, starting Feb. 2017.
(European) H2020 Project LightKone, starting Jan. 2017.
- The SyncFree EU project
(FP7 Strep) 2013–2016.
It aims to develop technologies for highly-scalable geo-replicated
computation and storage.
Building upon CRDTs, its academic
contributions include the planet-scale database AntidoteDB,
Consistency approach to tailoring consistency to application
requirements, the distributed programming language LASP,
and the framework for in-browser data sharing Legion.
Industrial outcomes include Basho's BigSet
technology, and ESL's WombatOAM
tool for system operations, administration and management.
CIFRE (industrial PhD grant) with Scality, on "CRDTs for large-scale storage,"
awarded to Tao Thanh
(ANR stands for
Agence Nationale de la Recherche, the research funding agency of
the French government.)
If you are interested in a PhD, send me a note.
You will need to demonstrate a strong academic record, real scientific
curiosity to explore the leading edge of technology and algorithms, and interest in research topics such as
distributed systems, distributed algorithms, replication and consistency,
databases, concurrent programming, etc.

- The ConcoRDanT ANR
project (2010—2013) aims to study commutative replicated data types,
a principled approach to eventual consistency.
- The Streams ANR project
(2010—2014) studies peer-to-peer, real-time collaboration.
- The Prose
ANR project (2009—2012) studies the sharing of
mutable content (e.g., a shared wiki) over opportunistic communication.
- PhD student Marek Zawirski received a Google
European Doctoral Fellowship towards his PhD on “Theory and
practice of shared data types for cloud computing”.
