Offer Description
Contexte et atouts du poste
The main goal of this PhD project is to develope a deep learning framework for the design of cyclic peptides. This project has an important impact on designing theraputics to fight emerging diseases. Moreover, we will take advantage of the recent advances of deep learning methods, investigate several algorithms, and ultimately provide an open source application to the broad scientific community. This approach is a prerequisite for the design of new therapeutic peptides that target macromolecular complexes.
The PhD candidate will be hosted in the CAPSID team within LORIA at the Inria, Nancy - Grand Est site. The candidate will be supervised by Yasaman Karami (Inria researcher) with expertise in analyzing proteins conformational dynamics and peptide design [1] and Hamed Khakzad (CPJ Inria) expert in artificial intelligence and protein design [2]. CAPSID team ( https://capsid.loria.fr/ ) is directed by Dr. Marie-Dominique Devignes and provides a multidisciplinary and international environment for students. The team benefits from experts in computational biology and structural bioinformatics, as well as in computer science. The group is equipped with a computational platform, MBI-DS4H ( https://mbi-ds4h.loria.fr/ ) composed of 8 nodes and 12 GPUs, and provides technical support to the users.

Mission confiée
Proteins often interact closely with other proteins to form a protein-protein interaction (PPI) network. Finely orchestrated PPIs are at the heart of virtually all fundamental cellular processes [1]. A large number of PPIs contribute to life-threatening diseases [2], and more than half a million PPI dysregulations have been found to be involved in pathological events [3]. Targeting PPIs is one of the main therapeutic strategies to fight against several diseases, and numerous experimental and computational approached were developed in this direction. The advantages of peptides (that are protein fragments) such as small surface area, weak target affinity and low specificity [4], resulted in a shift of the recent developments toward considering peptides for targeting PPIs. One recent example is the Spike of SARS-CoV-2 that binds to the human ACE2 receptor, for which the use of peptides to inhibit the PPI formed between RBD and ACE2 is a very active field of research [5]. Moreover, the recent advances of machine learning and deep learning in the CASP competition and the outbreak of AlphaFold2 [6] for the prediction of protein structures have shown that, they can improve discovery and decision making when high-quality data are available. The main goal of this project is to design head-to-tail cyclic peptides for targeting defined sites in proteins of interest. To achieve this objective, we propose the development of a deep learning architecture. Within the aims of the project, we will investigate several facets of the algorithms and the design processes, and ultimately provide this application to the broad scientific community. The main goal of the PhD project is to develop a deep generative model to design cyclic peptide sequences toward specific target. To do so, the student requires to have extensive background in deep learning and computational biology.
