Mission

  • Development of BioImage Analysis workflows and training to EPFL collaborators
  • Teaching during courses on image formation, image acquisition and image analysis.
  • Provide support and advice in the development of meaningful biological experiments where the output relies on image analysis.
  • Develop tools and algorithms using open source tools and promote Open Science whenever possible.
  • Disseminate SOPs on FAIR data practices.
  • Provide support to the greater imaging community through activity on the forum.image.sc .

CoPe candidacy

As an Imaging Scientist in a Core Facility, I am in contact with a broad community, which motivated me to join the Life Sciences Faculty Council. I am also committed to collaborating with my colleagues within ELSA to bring forward their concerns regarding working conditions to the CoPe. The creation of the Personnel Commission is an opportunity to further improve working life at EPFL, and I aim to contribute through fair representation, transparency, and constructive dialogue. 

Current work

Romain has been working at the BIOP since 2011 after a Ph.D. in Biology. He is responsible, along with Nicolas Chiaruttini and Rémy Dornier  for the advice and follow up of projects involving microscopy and quantification.

His expertise with in vitro cell culture and imaging is also beneficial to help BIOP users with their staining strategies and experiment design/optimization.

Teaching & PhD

Courses

Image Processing for Life Science

BIO-695

Registration details will be announced via email. It takes place yearly from Sept./October to December & intends to teach image processing with a strong emphasis of applications in life sciences. The idea is to enable the participants to solve image-processing questions via workflows independently.
