Research & Innovation - Internship 6 months – Scientific Computing - 2021 - M/W


For L’Oréal, beauty is above all a scientific adventure. This principle is reflected in the key role played by our Research & Innovation division, which deploys its teams all around the world to dream up and create the products of tomorrow.


But wait, have you heard about our history?

In 1909, Eugène Schueller, a young chemist, formulated the first hair dyes using a blend of harmless chemical compounds. With his entrepreneurial spirit, he sold it to Parisian hairdressers and founded the Société Française des Teintures Inoffensives pour Cheveux.


You never heard of that company? Don’t worry, we don’t blame you, because you know it under its current name: L’Oréal.


More than a century later, Eugene Schueller’s belief that research and innovation form the cornerstone of growth and success has spread to reach more than 3800 R&I employees, and enabled the discovery of over 130 molecules and the development of thousands of formulas and products.


Join us to become a L’Oréal Internpreneur!


Internship in Scientific Computing


Flexible starting date between January and July 2021 for 6 months, located in the Paris region



3 stages sont à pourvoir : 


MISSION 1 : Analyse statistique des données omiques fondée sur les graphes : développement et mise en place de la méthodologie.

    • Recherches bibliographiques sur les modèles graphiques (non dirigés et dirigés)
    • Application d’approches graphiques sur des jeux de données omiques en grande dimension (metabolomiques, microbiome)
    • Simulation données microbiome de nature compositionnelle pour l’évaluation de nos indicateurs de performances (alpha, beta diversité, analyse DESeq2) et des performances des approches graphiques
    • Implémentation de codes en R pour l’automatisation des analyses

Education and Training required:

  • Master 1 or 2 (you must have a « convention de stage ») in one of the following disciplines: 

Data science, Data Science applied to Biology, Statistics and Biostatistics, Sensory or Statistic analysis

Requis : Bonnes connaissances en mathématiques (statistiques, probabilités…), programmation en R, biologie computationnelle.

Facultatif : notion en théorie des graphes, connaissances en sciences du vivant



MISSION 2 : Development of a statistical tool for specific sensory analysis


The missions of Data Insight Team (Scientific Computing Department) at l’Oréal is to work in close collaboration with Laboratory, Advanced Research and Product Performance Evaluation (including Sensory Science and Consumer Science) to help them into decision making.

Our help consists in providing tools, algorithms, decision rules… based on a statistical expertise. The mission of this internship will focus on the collaboration with Product Performance Evaluation, specifically Sensory Science Teams. 

Today many analyses specific to sensory science are performed with external software. We want to develop the ability of performing these analyses in an internal platform. The aim of the internship will be to define what analysis are the most relevant to help sensory teams (among CATA, time intensity analysis, penalty analysis, free sorting…), set up adapted statistical methodologies and implement R code into an internal platform. 

The main deliverable of this project are:

  • An inventory of Sensory Science team needs
  • A state of the art to understand how this type of algorithms are developed in other tools (XlStat…)
  • A ready-to-use tool in R
  • A complete documentation on the methodologies and the way of using tool 

What profile are we looking for ?

  •  Master 1 or 2 Data Science or Sensory and Statistic analysis
  • Knowledge in Sensory Science: understanding of usual methodologies, data acquisition…
  • Strong knowledge in statistical and multidimensional data analysis
  • R/R Shiny programming
  • French and English written and spoken communication efficiency
  • You are well known for your incredible dynamism and your hands-on mentality
  • Result-oriented: you are not afraid to tackle challenges and solve problems thanks to creative solutions
  • You are a true team player, but also capable of working autonomously
  • Scientific excellence is your moto – you pay strong attention to details and are always seeking for new ways to innovate



MISSION 3 : Elicitation de prior pour calcul de grandeurs statistiques bayésiennes de prises de décision 

Au sein du Calcul Scientifique, les missions confiées au stagiaire seront les suivantes :

  • Veille bibliographique des méthodologies d’élicitation
  • Comprendre et mettre en place une stratégie d’élicitation de prior auprès des experts sur plusieurs domaines
  • Animer, préparer et organiser des réunions et accompagner les experts dans la définition des priors
  • Utiliser R pour générer les expressions mathématiques de ces priors
  • Rédaction d’une note synthétisant les conclusions obtenues
  • Application au calcul de grandeurs bayésiennes d’indicateurs de prises de décisions sur des études cliniques d’efficacité cosmétique

Le stagiaire, à travers ses missions, développera les compétences suivantes :

  • Approfondissement des connaissances en méthodologie statistique des études cliniques, en statistique bayésienne ainsi qu’en algorithmique
  • Aptitude à la synthèse et à la rédaction
  • Gestion d’un projet en autonomie
  • Aptitude à communiquer ses résultats scientifiques à un large public
  • Aptitude à fédérer des avis d’experts et à vulgariser des concepts scientifiques

Le stagiaire sera amené à faire des réunions de travail internes au Calcul Scientifique mais aussi en collaboration avec les métiers de la R&I.
