    实验室主页:

    https://team.inria.fr/morpheme/

    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 extractionDetection 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)。
