Entreprises

• Innopsys Company (Microarray Scanner Specialist) and LAAS-CNRS - R&D Physicist Engineer

  2015 - 2015 Innopsys develops, manufactures and commercializes microarray scanners and related software for biotechnological and medical research laboratories, combining cost-effectiveness with performance. Innopsys team is mainly composed of scientists and engineers, and distinguishes itself by its cutting-edge skills in various scientific and technical fields such as optics, micromechanics, onboard electronics, computing, nanotechnology and biology (http://www.innopsys.com/index.php).
  
  Project:
  
  As a part of its R&D project, Innopsys and LAAS-CNRS developed a recent partnership: Biosoft Joint Laboratory. This laboratory focuses on developing technological solutions in democratizing the in-vitro diagnosis (IVD) based on molecular assays and biochips at low cost for molecularizing point of care medicine. My project main objective was to develop a new polyvalent device for different applications related to medical and water diagnosis, as well as fluorescence imaging.
  
  Job responsibilities:
  
  I was in charge of developing the hardware of this optoelectronic instrument by taking into account the specificities of each targeted applications:
   Identification of technological needs working on optics designs, optics simulation (Zemax), lasers diode stability, CMOS camera technology and their temperature change over time;
   Conception, tests and characterization of a prototype for detection of biological interaction;
   Management of a multidisciplinary collaborative R&D project involving technical meetings and reports with partners.

• Nano-Bio physics division of the School of Physics of UCD in Ireland - Engineer Researcher

  2014 - 2014 The Nanophotonics and Nanoscopy Research Group focuses on studying nanoscale light-matter interaction processes. The laboratory works on designing new optically active nanostructures, and characterizing and understanding their physical properties. An important aspect of its research is to develop optical emitting device for sensing and diagnostics.

  Project:
  
  The need for discovering new material properties is a current challenge for our societies and for a large field of applications. To better understand these materials, it is necessary to develop techniques that enable nanoscale matter exploration and characterization. To do so, creating and applying AFM-IR, Raman and Fluorescence imaging based methodology could be performed. Using these optical systems allows studying the material optical emission specificities for future applications.
  
  Job responsibilities:
  
   Automation of a Raman spectroscopy system with LabVIEW for point mapping spectra acquisition. Fluorescence imaging on peptide nanotubes to study their optical and electrical properties. AFM-IR couple imaging system development based on quantum dots imaging and processing and the study of their single photon emission properties;
   Meetings, reports and day-to-day interaction in English with a multidisciplinary team in a multicultural environment.

• LPCNO - Engineer on a multidisciplinary project

  2013 - 2014 The LPCNO objective is miniaturizing solid-state devices to create objects with new properties that cannot be achieved in their macroscopic counterparts. These nano-devices can be used in various industry sectors such as telecommunication and information processing, transport, safety, health and environment.
  
  Project:
  
  Magnetic nanoparticles can be used to destroy tumorous cells using an external magnetic field. This process is based on the hyperthermia effect responsible for the cellular destruction. In this context, it is necessary to study the real impact of the nanoparticles in the process using a confocal microscope.
  
  Job responsibilities:
  
   Designing optimization, characterization and manufacturing a rotative magnetic field system adapted for confocal microscopy to treat cancer by hyperthermia effect, assisted with nanoparticles.
  

• INSA (National Institute in Applied Sciences) AIME Training - Engineer in a cleanroom environment

  2012 - 2012  Manufacturing photovoltaic cells process in a cleanroom environment (whole cycle: conception, front-end and back-end).
   Modelling (CAD), manufacturing and characterizing silicon transistors and memories.
