  • altran

    April - September 2019

    Data Scientist in Medical imaging - Altran Research, Vélizy-Villacoublay

    Application of machine learning methods on radiomic data, and deep learning techniques on MRI images, to classify, detect and segment benign and malignant tumors (lipomas and liposarcomas). Nowadays, the diagnostic of the latter is made by biopsy after an MRI scan. However, the malignant/benign ratio is very low for these tumors, so most of the biopsies are unnecessary. A diagnosis made directly from MRI images would be an interesting alternative, both for patients who would avoid an invasive examination, and for medical structures that would save money and time.
    The goal of the internship is to write a research article where different approaches and techniques are compared.

    Work in collaboration with the biomedical imaging research laboratory CREATIS.

  • softbank-robotics

    April - August 2018

    Full Stack Developer - SoftBank Robotics Europe, Paris

    I joined the System Integration & Verification department. The members of this team are in charge of planning and performing hardware tests, in order to check the validity of the robots before their production. The internship mission was to create an archiving system to store the data from the tests performed on NAO and Pepper.
    I have developed a web application based on a RESTful API, which is now deployed and used in several departments of SoftBank Robotics.
    The application, named A.S.T.R. - Archiving System Truly RESTful, and the Python library are Open Source and available on the GitHub of the company.

    ➢ Elaboration of specifications.
    ➢ Technology choices.
    ➢ Development of the web application (API and website).
    ➢ Development of a Python library.
    ➢ Managing the sending of large files to the server.
    ➢ User management.
    ➢ Advanced archive search.
    ➢ Deployment management.

    ✹ Techs used : Node.js, MongoDB (NoSQL), Express, Python, Git, Docker, Ansible
    ✹ Environment : Linux
    ✹ Source code : the web application and the Python library

  • fishfriender

    June - July 2017

    Developer Node.js - Fishfriender, Paris

    FishFriender is an online platform that aims to modernize the angling industry.

    ➢ Mission: automate data recovery and process partner data to adapt and insert them into the application database. The partner data were either in Excel sheets or in web pages. I extracted the data using web scraping techniques.

    ✹ Tech used: Node.js, JavaScript, SQL, JSON.
    ✹ Environment: Mac OS

Domain Adaptation

The key to deploy algorithms on a large scale

A powerful detection algorithm for one medical center, but unsuitable for another. This is one of the major problems faced by research teams wishing to deploy their models on a large scale. In this article, I introduce this challenge called Domain Adaptation in the context of medical imaging, based on my experience at AZmed.

Data viz: VAST Challenge

Visualization and Machine Learning

Development of various visualizations to respond to the VAST mini-challenge 1 of 2018. The goal was to discover if the actions of a company had led to the migration of birds. Spatio-temporal data analysis led to the development of an interactive map to observe the movements of different species. Spectral analysis of bird songs has also revealed interesting facts.
