Computational morphometry and morphodynamics of cellular and supracellular structures

Joint team between Inria, CNRS and Université Côte d’Azur (UCA), affiliated with Inria SAM, Computer Science+Signals+Systems Laboratory (I3S) and Institute of Biology Valrose (iBV)

History: Creation process started in 2010; Status of « Equipe-Projet Commune (EPC) » in 2013; Renewal in 2017

Objectives

• Positioning: Be at the interface between computational science and biology

• Motivation: The morphology and topology of mesoscopic structures have a key influence on the functional behavior of organs

• Objectives: Characterize and model the morphological & topological properties, and the development of biological structures

• Framework:

• Scales: from cell to supracellular scale

• Modalities: various microscopy systems (confocal, 2-photon, phase-contrast, video, micro-tomography)

• Data: in vivo images in 2D, 2D+t, 3D or 3D+t

• Tools: image processing, statistical learning and computational modeling

• In the long term: Allow for a better understanding of the development of normal tissues and a characterization at the supracellular level of pathologies such as the Fragile X syndrome, Alzheimer or diabetes.

4 Research Axes

• Image acquisition. Includes:

• For a given biological question, definition of studied phenomena (experimental conditions) and preparation of samples

• Optimization of the acquisition protocol (staining, imaging…) and definition of relevant quantitative characteristics

• Reconstruction/restoration of native data to improve the image readability and interpretation

• Structure extraction
  Detection and delineation of the biological structures of interest in images, which includes the use of previously defined models for improving the detection. Two main challenges are the variability of biological structures and the huge size of datasets

• Interpretation/Classification. Includes:

• Inference of parameters associated with the model that has been used to extract the biological structure under study

• Definition of classification schemes for characterizing the different populations based either on the model parameters or on some specific metric between the extracted structures. The aim is to provide biological information characterizing the different populations

• Modeling. Back-and-forth approach:

• Forth approach: modeling biological phenomena such as axon growth or network topology in different contexts using image-based information to calibrate/validate the models

• Back approach: using a prior model to extract relevant information from images

说明：由于疫情原因，经费紧张，需要申请CSC（China Scholarship Council，即国家留学基金）。
