His research interests span formal methods, their applications to improve software quality and packages upgrades, as well as Free Software evolution.

He has been an official member of the Debian Project since 2001, where he worked on many tasks, from package maintenance to distribution-wide Quality Assurance. He has been elected to serve as Debian Project Leader (DPL) for 3 terms in a row, during the period 2010-2013. He is a Board Director of the Open Source Initiative (OSI) and a recipient of the 2015 O’Reilly Open Source Award.


Gérard Berry (French Academy of Science)

A graduate of the Ecole Polytechnique and the Ecole des Mines, he completed a PhD in mathematics in 1979. From 1973 to 2001, he worked at Ecole des mines and Inria, first on the syntax and semantics of functional programming languages, then on the development of the Esterel language. This language is used for the programming of safety-critical embedded systems and electronic circuits. In 2001, he joined the Esterel Technologies company as its Scientific Director. He returned to research at Inria in 2009, and joined Collège de France in 2012 on the Chair Algorithms, Machines, and Languages, after having held two yearly chairs there in 2007-2008 and 2009-2010.

A member of the Académie des sciences since 2002, world-renowned researcher Gérard Berry is also a passionate and engaging teacher. For several years, he has been working with various audiences to demonstrate how much digital technology shapes our everyday lives. This was the subject of his inaugural lecture How and why the world is turning digital when holding the  Liliane Bettencourt Technology Innovation chair at Collège de France in 2008.

His work has won him many honours, including the CNRS bronze medal in 1979, the Ministry of Defence’s prize for Science and Defence in 1999, the EADS Foundation’s Grand Prize for industrial applications of science in 2005, and the Gold Medal of CNRS in 2014.

Jean-François Abramatic (EIT)

A senior scientist at Inria, his career has been shared between research and industry. He started as a research scientist in differential games and digital image processing.

As Director of Development and Industrial Relations at Inria, he launched the European host of the World Wide Web Consortium (W3C) and then moved to MIT as W3C Chairman from 1996 to 2001.

He has been Vice President of Research and Development of the software company ILOG, until after its acquisition by IBM, and then became Director of Development Productivity & Innovation in the IBM Enterprise Transformation division.

In 2014, he returned to Inria in the Transfer & Innovation division. He has served on the ICANN Board and is currently a member of the governing board of the European Institute of Innovation & Technology (EIT) and a member of the Coordination Council of the NETmundial Initiative.

Julia Lawall portrait
Julia Lawall (Inria)

Julia Lawall has been a senior scientist at Inria since 2011, and was previously on the faculty of the University of Copenhagen.

Her research interests are primarily in the area of improving the quality of infrastructure software, using a variety of approaches including program analysis, program transformation, and the design of domain-specific languages.  She is active in the systems, software engineering, and programming languages research communities.

The main focus of her research is centered around the tool Coccinelle for matching and transformation of C code.  Based on her research, she has been an active participant in the Linux kernel developer community, with over 1700 patches accepted into the Linux kernel. Coccinelle is currently widely used by other developers of the Linux kernel and other C infrastructure software.

Serge Abiteboul (French Academy of Science)

Serge Abiteboul obtained his Ph.D. from the University of Southern California, and a State Doctoral Thesis from the University of Paris-Sud. He has been a researcher at the Institut National de Recherche en Informatique et Automatique since 1982 and is now Distinguished Affiliated Professor at Ecole Normale Supérieure de Cachan. He was a Lecturer at the École Polytechnique and Visiting Professor at Stanford and Oxford University. He has been Chair Professor at Collège de France in 2011-12 and Francqui Chair Professor at Namur University in 2012-2013. He co-founded the company Xyleme in 2000.

Serge Abiteboul has received the ACM SIGMOD Innovation Award in 1998, the EADS Award from the French Academy of sciences in 2007; the Milner Award from the Royal Society in 2013; and a European Research Council Fellowship (2008-2013).

He became a member of the French Academy of Sciences in 2008, and a member the Academy of Europe in 2011.

Visiting hackers

Avi Kelman

Avi is a wandering underwater roboticist by day and a Free Software, community, and sharing advocate by night. He believes that historical preservation of ephemeral information is critical to understanding our societies and that the worst feeling in the world is the one you get when you can’t find something that you are certain should be there. One of his goals as visiting hacker is to make external code contributions to the project easier for people by reducing the necessary cognitive load.

Visiting scientists

Guillaume Rousseau

Guillaume holds a Ph.D in Astrophysics and Space Technologies from University Paris Diderot, and is currently Associate Professor at the department of Physics of University Paris Diderot.

His research interests span modeling and simulation of complex system applied to a wide range of scientific fields including coupling between radiative transfer and stiff chemical reaction in molecular cloud of the interstellar medium, atrial fibrillation, transition to turbulence via spatio-temporal intermittency, and more recently modeling and indexing of large scale  systems applied to software development communities.

In the scope of the software heritage project, Guillaume will work on some of the exciting challenges as visiting scientist and will contribute with his experience in building Antepedia, one of the largest knowledge base of software artifacts.


Morane Gruenpeter

After several years as a professional harpist Morane found a new career path in software engineering.

Morane joined the Software Heritage team as an intern in 2017 while finishing a Master’s degree in Computer Science at University Pierre et Marie Curie. Her internship’s goal is building the Semantic Web of FOSS projects by collecting existing metadata, reconciliating them to some extent, and integrating them into the Software Heritage archive.
