SABILab is a consulting company that aims at supporting scientific research by providing data/bio-image analysis expertise to scientists. It also has an academic research activity.

How Can We Help?

Here are examples of service we can provide:

  • Diagnostic on the whole data production pipeline (data acquisition, image processing, statistical processing)
  • Design and implementation of a data analysis pipeline using open-source software
  • Design and implementation of tailored image processing methods (see examples in my research works page)
  • Training: image analysis, deep learning, statistical processing with R or Pandas (python)

Jean Ollion

Founder of SABILab

ID I was trained as a scientist at Polytechnique then Sorbonne Université with a double expertise in cell biology and bio-image analysis. During both my PhD and Post-doc, I divided my work between experimental work in biology and bio-image analysis. I developed two software: TANGO for 3D analysis of nuclear organization and BACMMAN for high-throughput analysis of Mother Machine
The Mother machine is a popular microfluidic device that allows long-term time-lapse imaging of thousands of cells in parallel by microscopy. It has become a valuable tool for single-cell level quantitative analysis and characterization of many cellular processes such as gene expression and regulation, mutagenesis or response to antibiotics.

I am now working as data scientist and bio-image analyst, providing data analysis expertise to scientists. My knowledge and experience in biology facilitate a deep understanding of the scientific problematic and technical stakes behind the data. I also maintain a research activity, and recently developed an original bio-image processing method involving deep learning. I am currently developing a general purpose denoising method based on deep neural networks.
