The research project, whether experimental or theoretical, must be convincing in its originality and its ability to go beyond the state of the art. It should be in the field of spintronics, but could also be at the interface between spintronics and other fields of condensed matter physics, such as superconductivity, light-matter interaction, innovative low-dimensional materials, and quantum physics, without being exhaustive.

Quantum Computing and noisy intermediate-scale Quantum Computer (QOQTIB)

Significant research has enhanced our understanding of the potential of ideal, large-scale, error-free quantum computers. However, current technological progress only allows for the consideration of limited-size, imperfectly functioning devices. These systems could still achieve significant breakthroughs once their potential is better understood.
The tenure track aims to support this effort by recruiting a researcher in theoretical physics and/or computer science working on such systems. This could involve assessing their potential as computational tools, developing strategies to improve their accuracy, adapting algorithm development to existing platforms, or creating methods to better understand their robustness and dynamics using mathematical, algorithmic, analytical, and/or numerical tools. Candidates will propose a research project that integrates with one or more of the host laboratories.

Ecology and environment
Functional ecology of lotic ecosystems (ECOFEL)

Appraise consequences of global change on lotic ecosystems

Nuclear and particle physics
Nuclear Data : from fundamental nuclear physics to reactors (DATANUC)

The physics of the atomic nucleus plays an essential role in the study of nuclear reactor operation. Neutron-induced nuclear reactions provide the nuclear data needed to better understand and predict reactor operation. The recent commissioning of the Neutrons for Science facility at GANIL opens up new possibilities for the study of neutron-induced nuclear processes, and for high-precision measurements of neutron-induced reaction cross sections. The tenure track project will focus on NFS measurement campaigns, data analysis and instrument development.

Precision cosmology with gravitational shear in LSST (LSSTLens)

The standard model of cosmology (ΛCDM), established in the early 2000s, relies on two still mysterious components: dark matter and dark energy. The latter, of unknown nature and with repulsive properties presents a major challenge. It could either be a new constituent of the Universe or a sign of a deviation from general relativity. Determining its true nature requires precision tests of cosmic expansion and the history of structure formation. This second domain, still poorly constrained, is key to testing General Relativity and exploring potential alternative theories of gravitation on large scales.

The Legacy Survey of Space and Time (LSST) has been specifically designed to study correlations in gravitational shear (weak-lensing), providing direct access to the foreground matter distribution. Conducted at different redshifts, this technique allows researchers to reconstruct the history of structure formation and test the validity of gravitational laws on cosmological scales. LSST will also collect thousands of Type Ia supernovae, enabling a precise mapping of cosmic expansion. The analysis of supernova velocities at low redshift will help measure the structure growth rate.

The CPJ chairholder will strengthen these efforts by participating in the extraction of the gravitational shear signal from the LSST data, and by combining weak lensing and galaxy clustering data from the Dark Energy Spectroscopic Instrument (DESI) to constrain dark energy and explore the foundations of modern cosmology.

Higgs physics at the LHC and CMOS pixel detectors of the future (HIPIFU)

The Higgs boson plays a major role in understanding the links between the infinitely small, the elementary particles, and the infinitely large, the origin and evolution of the Universe. To make progress on these questions, the determination of the Higgs boson's couplings and the search for physics beyond the Standard Model are key topics. The CPJ chairholder will on one hand have the opportunity to make major contributions to this research in the CMS experiment at CERN's LHC, and will also lead the definition of a high-performance and innovative pixel detector for a future Higgs factory such as CERN’s FCC-ee, building on the local expertise in this area.

Understanding the Extreme Universe with CTAO (CUE-CTAO)

The processes that accelerate particles to ultra-relativistic energies, producing radiation at levels unattainable on Earth, and the cosmic environments where this occurs are often poorly understood. This radiation is linked to matter configurations with strong gravity and/or magnetic fields, such as supermassive black holes in galaxies (AGN), fast-rotating neutron stars (pulsars), and supernovae marking the end of massive stars. The Cherenkov Telescope Array Observatory (CTAO), currently under construction, will be the largest very-high gamma-ray observatory on Earth, dedicated to studying gamma-ray radiation from these objects at the highest energies (10 GeV to 100 TeV) to uncover the underlying processes. The tenure-track position (CPJ) will be deeply involved in the exploitation and operation of CTAO over its expected 30-year lifespan. This position is critical, with construction ending in 2029 and the commissioning phase starting in 2026.

The general objective of this project is to strengthen CNRS activities in the field of robotics, control engineering, and AI for autonomous systems interacting with humans, with two main research axes: developing new control approaches and architectures for autonomous vehicles taking into account human aspects, including the development of observers and estimators exploiting available data, and learning driving situations to adapt to driver preferences and constraints and enhance human driving capabilities in complex environments to improve safety and facilitate driving using technologies from robotics, autonomous systems, and artificial intelligence.

Perception and understanding of situations in open and dynamic environments, as well as vehicle uncertainty management and integrity, are major challenges addressed in this project, aiming to strengthen excellence laboratories in the field.

Digital biology (BioNum)

This tenure track in computational and/or digital biology applied to health is devoted to the development of therapeutic methods through multi-scale characterisation of the mechanics of biological responses, modelling of radiation-tissue interactions and associated image processing. The aim is to better understand, predict and control the plasticity and cellular/tissue dynamics of tumours by integrating their environment when they are subject to standard treatments or innovative strategies. The methodological challenges are therefore to observe, characterise and simulate multi-scale biological or biophysical phenomena by developing ex vivo numerical or biological models. The models obtained will be used to help make therapeutic decisions based on preclinical clinical or biological data, to gain a better understanding of treatment response processes and to optimise therapeutic strategies..

Robotics, anthropomorphic motion and human-robot interaction (RoboMouv)

Modeling and simulation of human behavior and interaction with robots are very active research topics at the interface of robotics, virtual reality and haptics, and extend from biomechanics to human motion analysis. Human-robot interaction is very rich in scientific problems that can be used to solve important practical robotic problems: role management between robot and human, multi-sensory feedback (visual, haptic), shared control algorithms to manage redundancy and the constraints of one or more robots, balance, motion planning. Added to this is the recent development in the field of machine learning methods, with the possibility of learning, imitating or reproducing human capacities for action and interaction with robots, by exploiting methods for synthesizing human movement, whether through kinematic or dynamic approaches.

Imaging extended to multimodal data processing (IDM)

Being able to exploit massive imaging data in a clinical context is a major challenge in order to design, develop, evaluate and validate new approaches to analyze this data, with a much more integrated, transdisciplinary and translational vision. This involves integrating heterogeneous data and modelling patient care trajectories, including medical images, radiological reports, hospital and biological data. This should enable these multimodal data to be monitored longitudinally, in order to identify the factors that determine the effectiveness of treatments. The aim is also to identify and validate complex biomedical signatures from multimodal and multiscale sources (multi-parametric MRI, EEG, ECG, ultrasound imaging, biomolecular, genetic and phenotypic data, etc.), in order to reveal underlying pathological mechanisms and guide therapeutic approaches. To meet these challenges, the CNRS is offering a tenure track.

Molecular Modeling and Simulation Methods (MMSMM)

This tenure track in machine learning for structural bioinformatics focuses on solving algorithmically complex problems with therapeutic applications. The project, centered on hybrid methods (AI, algorithms, physics, statistics), aims to model and characterize the conformational and dynamic properties of the most flexible biomolecules, such as disordered protein regions and coding or non-coding RNAs. The targeted properties include thermodynamic and kinetic behaviors, the impact of environmental conditions, the effects of post-translational modifications, and the prediction of interactions. The project seeks to address challenges related to the design of such molecules and their regulators in the medical field. To overcome limitations caused by the scarcity of data on these molecules, the project will leverage collaborations with experimental biophysics, in vitro biology, and biochemistry laboratories.

Mathematics

These approaches promote a deeper understanding of life, from the molecular level to that of ecosystems, by developing appropriate mathematical tools (analysis, simulation, AI).

Analysis (Analysis)

Analysis in all its forms is at the heart of this tenure track position (CPJ) . A historical field of infinitesimal calculus, the study of partial differential equations and the calculus of variations, analysis also includes areas with major applications related, for example, to frequency analysis in all its forms. The geometric or dynamic aspects of analysis, or those related to alea, are also relevant to this professorship.

Formalizing ecological and evolutionary processes using biomathematical, biostatistical and bioinformatics approaches (PROBIE)

Formalising ecological and evolutionary processes using biomathematical, biostatistical and bioinformatics approaches is essential to understand the complexity of living systems on extremely varied time and space scales. Modelling, scenario-building and prediction are at the heart of many of today's scientific and societal challenges. They are based on the availability of unprecedented, increasingly massive and heterogeneous data, requiring the development of new mathematical methods, particularly in digital simulation and artificial intelligence.

In the event that your disability or state of health changes between the date of your request for accommodations and the date on which the tests take place, you will need to provide additional documents within the timeframe required to enable them to be taken into account.

For candidates from overseas or living abroad, pregnant candidates and candidates whose state of health justifies it, the audition is organized by videoconference on request at the time of registration. Contact the Competitive Examinations Department at: drh-seri.accueils@cnrs.fr
