Responsable :
Georges Aad - aad@cern.ch
Description :

Applications are invited for a post-doctoral position in the ATLAS group at the Center for Particle Physics of Marseille (CPPM), France. The successful candidate is expected to work on the development of Artificial Intelligence (AI) algorithms applied to hardware processing units based on FPGAs for the phase II upgrade of the ATLAS detector.


CPPM is involved in several major projects in experimental particle physics, astroparticle, cosmology and interdisciplinary applications. The ATLAS group at CPPM gathers about forty-five people, including fifteen staff physicists and ten PhD students. The group played a major role in the design and construction of the electromagnetic end-cap calorimeters, the pixel detector and the trigger system, and pursues a strong R&D effort for planned future upgrades of the detector, notably for the Liquid Argon (LAr) calorimeter, as well as a key contribution to physics analysis in ATLAS.


The successful candidate is expected to take a leading role in the development of data processing algorithms allowing to efficiently compute the energies deposited in the LAr calorimeters in the high pileup conditions expected at the HL-LHC. These algorithms will be based on AI techniques such as recurrent neural networks and will be adapted to fit on hardware processing units based on high-end FPGA. The successful candidate will be responsible of designing the AI algorithms and assessing their performance. The candidate will also assess the effect of employing such algorithms for electromagnetic object reconstruction (especially at trigger level) and for benchmark physics analyses. She/he will work closely with the engineers designing the electronic cards at CPPM in order to adapt the AI algorithm to the specifics of FPGAs. Candidates with a strong interest for hardware will be encouraged to take part in the design of the firmware to program the FPGAs.


The position is for a fixed term of three years, and is based in Marseille, with frequent trips to Geneva. The starting date for the position is beginning 2021. Candidates should have a PhD in experimental particle physics by the date of appointment. Good communication skills are expected.


Candidates are invited to send their complete application package (CV, cover letter and statement of research interests, list of publications) to aad@cern.ch and monnier@in2p3.fr, and to arrange for three letters of recommendation to be sent directly to the same addresses. The review of applications will start in December 2020 and will continue until the position is filled. Applications received by 31st of December 2020 will receive full consideration.


Further inquiries about the CPPM ATLAS group and the position should be addressed to Georges Aad (aad@cern.ch) and Emmanuel Monnier (monnier@in2p3.fr).

Yannick Boursier - 04 91 82 76 41 - boursier@cppm.in2p3.fr
Description :

Contract Period : 24 months

Expected date of employment : September 2021

Proportion of work : Full time

Remuneration : Between 2728 et 3145 euros according to experience

Desired level of education : PhD

Experience required : Indifferent


Missions


The research work is part of the TIARA project, which aims to provide an instrumental, methodological proof of concept on real data of the real time monitoring of the emission distribution of Gamma Prompts (GPs) in the context of hadrontherapy. A detection system placed around the patient - composed of an hodoscope and gamma detectors with a temporal resolution of 100 ps - provides time of flight measurements of the particles involved in the treatment. The first objective of the proposed mission is to exploit these data to be able to detect as soon as possible a significant divergence between the real treatment and the treatment plan (simulated upstream), and to stop the treatment if necessary. The final goal is to be able to estimate the distribution of GPs' vertices with a sufficient accuracy to adjust the treatment in real time with respect to the treatment plan. Access to this type of information could also pave the way for measuring the actual dose distribution delivered.


Activities


He/she will develop a research activity at the interface between data sciences and medical physics in order to explore applications of artificial intelligence for time-of-flight data in hadrontherapy. He/she will pursue the following main objectives: i) to improve our approach to 3D GPs vertex reconstruction based on an optimization problem that incorporates the physics of hadrontherapy (e.g. by analyzing simulated and real available data in order to incorporate suitable regularizations like low-rank+sparse). The results obtained at this stage will allow in particular to optimize the design of the instrument for a maximum spatial resolution; ii) to evaluate the contribution of machine learning and deep learning methods to jointly estimate the 3D distribution of GP vertices and the anatomical changes (i.e. of electron density) between the time of the treatment plan and the time of the actual treatment. This essential quantity is often estimated beforehand with significant uncertainties that must be compensated. Different strategies will be studied (transfer learning, use of Generative Adversarial Networks) and the most relevant ones will be evaluated on real data with the feedback of physicians and radiophysicists.


Skills


The candidate should have operational skills in data science, optimization methods and/or machine or deep learning.

Interest in applications in the medical field will be appreciated. Knowledge of the context and/or science of medical physics, specifically radio/hadron therapy will be appreciated.

Ability to work in an interdisciplinary environment.


Work Context


The researcher will be part of the TIARA project (Time-of-flight Imaging ARrAy for real-time monitoring in hadrontherapy) financed by the Inserm Cancer Plan, PCSI 2020 (Physics, Chemistry or Engineering Sciences applied to Cancer), a tripartite collaboration between the Laboratoire de Physique Subatomique \\& Cosmologie (LPSC) in Grenoble, the Centre de Physique des Particules de Marseille (CPPM) and the Centre Antoine Lacassagne (CAL) in Nice. In this project, the CPPM is responsible for the development of the data processing methodology.

He/she will benefit from the multidisciplinary, rich and stimulating work environment of the imXgam team, the CPPM and the Luminy Campus, including access to the know-how and computing facilities of the IN2P3 Computing Center.


Constraints and risks


The research work will be done in close collaboration with the LPSC team specialized in hadrontherapy physics and will require 1-2 days working visits at LPSC, Grenoble and CAL, Nice.
