Research Director at CEA, François Terrier is in charge of the Artificial Intelligence program at CEA. After a PhD in AI and 10 years of R&D in the field, he conducted research on software engineering and trust systems. Author of more than 100 publications, he was the CEA representative in the network of excellence on real-time systems led by Joseph Sifakis, and a player in the standardization of this topic at the OMG. Department head from 2010 to 2020, he was in charge of the development of activities on model-based engineering and formal methods that led to the production of international open source platforms (Papyrus, Frama-C). In this mission, he supported the emergence of new activities on cyber security, resilient distributed systems, including blockchain. Thanks to his dual culture in AI and trust systems engineering, he has built the CEA's artificial intelligence of trust axis, which he pilots and deploys in various projects such as confiance.ai and the European network of excellence TAILOR.

Emmanuel Vazquez is a researcher in the field of Bayesian design and analysis of computer experiments (Bayesian DACE). He teaches Bayesian statistics at CentraleSupélec. He is also the coordinator of data science projects. In the past, he has also taught functional analysis and probability theory.

The design and analysis of computer experiments consists in using statistical approaches to solve problems such as approximation, uncertainty quantification, optimization... involving computer programs (or simulators) that emulate physical systems (see, for example, Santner 2003). His work is based on Bayesian sequential decision theory. In the domain of computer experiments, the Bayesian approach begins with a prior distribution that represents our prior belief about the structure of the computer model. The use of this approach for computer experiments emerged in the 1980s (see the seminal paper by Sacks et al. 1989).

His research activity is focused on the evolutionary analysis of genomes and biological networks. In this context, Olivier Lespinet is involved in the development of several projects, the most significant of which are described below :

• The evolution of synteny in prokaryotes

The exhaustive comparison of the sequences of several hundred prokaryotic genomes has allowed us to identify numerous families of orthologous genes, i.e. sets of genes that have a common ancestor and that are related to each other only by speciation events. Among these families, we looked for orthologous genes whose neighborhood is conserved during evolution. These groups of genes constitute what is called synteny blocks.

• The discovery and identification of orphan enzymatic activities

Each original enzymatic activity is associated with a unique identifier consisting of a series of 4 digits called EC number. This identifier allows to indicate in a precise and univocal way the biochemical function of each enzyme. For example the EC number 1.1.1.1 is associated with enzymes of the alcohol dehydrogenase type.

• Annotation and genome analysis of the filamentous fungus Podospora anserina

Podospora anserina is a filamentous fungus of the class Ascomycetes that grows on the excrement of herbivores. It is also a model organism that has been used in genetics for more than 60 years to study different fundamental biological processes such as meiosis, aging or prion-like proteinaceous inheritance mechanisms. The nuclear genome sequence of the S mat+ strain of Podopsora was determined and assembled by the Genoscope. It is a 10X coverage obtained by a Shotgun approach.

• Study of the diversity, dynamics and evolution of biological networks

The study of biological networks (genetic regulation networks, protein interaction networks, metabolic networks) is a good way to understand how life evolves and functions. Apart from purely experimental approaches aiming, for example, at listing the proteins interacting with each other in a given physiological condition for a particular organism, in silico approaches based on these experimental data coupled with comparative genomics approaches also allow today to study biological networks.

She is now a research director at INRAE. Since 2015, she is the head of the MaIAGE laboratory. She is also the scientific leader of the bioinformatics facility Migale.

Research area
Her main interest is to develop statistical methods for genome and metagenome analysis. Her favorite objects are DNA motifs in all their forms: words, kmers, degenerate words, structured motifs, positional weight matrices, exact maximum matches, etc. She mainly studies their frequency but also their structure. She mainly studies their frequency but also their localization along the genome, by looking for co-localized motifs. She initiated and participated in the development of the R'MES software, which evaluates the statistical significance of the number of motifs in DNA sequences.
In recent years, she has been particularly interested in the study of microbial ecosystems in her laboratory.
