Benoit Dehapiot (CENTURI Multi-engineering platform)

Image processing & data analysis

His background

September 2019 - Present | Data analyst – image data processing (Research engineer), CENTURI multi-engineering platform, Aix-Marseille Université, France

2014 - 2018 | Postdoctoral fellow, Institut de Biologie du Développement de Marseille (IBDM), France

2010 - 2014 | PhD, Institut de Génétique et Développement de Rennes (IGDR), Université de Rennes 1, France

2005 - 2010 | BSc and MSc, Cell Biology and Genetics, Université de Rennes 1, France

I am a biologist by training with a solid expertise in live imaging, image processing and data analysis. During my PhD (IGDR, Rennes), I studied the mechanisms underlying the asymmetric division and the cortical polarization of mouse oocyte. As a postdoctoral fellow (IBDM, Marseille), I studied the apical contractility of epithelial cells during Drosophila embryos morphogenesis. I particularly focused on understanding how the cortical F-Actin transduces MyoII contractile forces to the cell periphery. Throughout my research path, I developed a keen interest in interdisciplinary research at the interface between biology, physics and computer science.

As a research engineer in image data processing within CENTURI multi-engineering platform, I am in charge of providing advice and support to researchers and students concerning image processing and data analysis. Moreover, I organize and conduct courses about these topics and assist in technology transfer between the teams of the CENTURI project.

 

I would be particularly able to help you with:

 

  • Biological sample imaging (optical microscopy)

- To produce a reliable data set ready for image analysis

  • Fluorescence quantification

- Considering problematics such as background subtraction and normalization

  • Object segmentation

- Using thresholding, pixel classification or watershed algorithm

  • Flow measurement

- Using particle image velocimetry (PIV) or discrete particle tracking (STICS, KLT)

  • Signal processing

- FFTs and IIR bandpass filtering
