A propos du centre ou de la direction fonctionnelle
The Inria center at the University of Rennes is one of eight Inria centers and has more than thirty research teams. The Inria center is a major and recognized player in the field of digital sciences. It is at the heart of a rich ecosystem of R&D and innovation, including highly innovative SMEs, large industrial groups, competitiveness clusters, research and higher education institutions, centers of excellence, and technological research institutes.
Contexte et atouts du poste
Large language models, such as those powering ChatGPT, have transformed natural language processing and the analysis of complex sequential data. In biology, protein sequences can be viewed as a language, opening new perspectives for functional annotation.
The ECxit project ( Exiting the EC Classification for Better Enzyme Annotation by Deep Learning ), an Inria Exploratory Action led by François Coste , focuses on enzyme function annotation. By moving beyond the traditional EC classification, it aims to develop a novel deep learning-based annotation framework built on a redesigned hierarchical classification of enzymatic functions, enabling accurate predictions directly from amino acid sequences and ultimately improving genome annotation.
The project is hosted within the Machine Learning axis of the new Bioinformatics research team BioGraphs (formerly Dyliss ) at the Inria Centre at Rennes University and the IRISA research laboratory . It benefits from the Genouest platform and from close collaborations with research groups in bioinformatics, biology, and health sciences.
Mission confiée
With the support of researchers from the BioGraphs team, the recruited person will contribute to the design and development of a novel framework for enzyme function annotation based on deep learning and protein language models.
The recruited person will be involved in the development of a new hierarchical classification of enzymatic functions, the construction of reference datasets and benchmarks, the evaluation of state-of-the-art prediction methods, and the deployment of a new annotation tool for the biological community.
