A propos du centre ou de la direction fonctionnelle

The Inria center at Université Côte d'Azur includes 42 research teams and 9 support services. The center's staff (about 500 people) is made up of scientists of different nationalities, engineers, technicians and administrative staff. The teams are mainly located on the university campuses of Sophia Antipolis and Nice as well as Montpellier, in close collaboration with research and higher education laboratories and establishments (Université Côte d'Azur, CNRS, INRAE, INSERM ...), but also with the regional economic players.

With a presence in the fields of computational neuroscience and biology, data science and modeling, software engineering and certification, as well as collaborative robotics, the Inria Centre at Université Côte d'Azur is a major player in terms of scientific excellence through its results and collaborations at both European and international levels.

Contexte et atouts du poste

This engineering internship position will take place in the environment of the Inria-Inserm team COMPO (COMputational Pharmacology in Oncology), located in the La Timone health campus. The team is composed of mathematicians, data scientists, pharmacists and clinicians and is a unique multidisciplinary environment focused on developing novel computational tools for decision-making in clinical oncology.

Mission confiée

Liquid biopsy has established itself as a powerful tool for the early detection of cancer and the diagnosis

diagnosis, prognosis and treatment monitoring in a wide range of cancer types. As part of the

SChISM (Size Cfdna Immunotherapies Signature Monitoring) project, the COMPO team is studying the

fragmentome, i.e. the size distribution of circulating cell-free DNA fragments, and has obtained significant

from individual markers (Salas et al., ASCO 2024, ESMO 2024).

The aim of this internship is to evaluate, develop and implement machine learning analyses to develop

analyses to develop two predictive algorithms by combining simple markers into multivariate

multivariate models: one for screening (cancer versus healthy) and the other for resistance to2

immunotherapy. The analyses will involve two stages: variable selection and modelling,

using learning algorithms evaluated by controlling optimism (overlearning).
