7th Croucher-Pasteur Exchange Programme: Dr OLIVO-MARIN

Dr Jean-Christophe OLIVO-MARIN (Quantitative Image Analysis Unit, Institut Pasteur, Paris, France) has given a seminar on April 12, 2011 entitled: "Cells, images and numbers".

Date: Tuesday, 12 April 2011

Time: 2:00 p.m. - 3:00 p.m.

Venue: Seminar Room 7, LG/F, Laboratory Block, Faculty of Medicine Bldg, 21 Sassoon Road, Pokfulam, Hong Kong


The lecture will present specific methods and algorithms for the processing and quantification of 2- and 3-D+t images sequences in biological microscopy. We will demonstrate algorithms of PSF approximations for image deconvolution, image segmentation, multi-particle tracking and active contours models for cell shape and deformation analysis. We will illustrate the application of our methods in projects related to the study of the dynamics of genes in cell nuclei, the movement of parasites in cells and the detection and tracking of microbes in cells. One specific goal in biological imaging is indeed to automate the quantification of dynamics parameters or the characterization of phenotypic and morphological changes occurring as a consequence of cell/cell or pathogens/host cells interactions. The availability of this information and its thorough analysis is indeed of key importance to help deciphering underlying molecular mechanisms of infectious diseases.

Croucher-Pasteur Exchange Programme: In collaboration with the International Affairs Department of Institut Pasteur and the Croucher Foundation, the Centre is establishing an exchange programme for students and post-doctoral fellows resident in Hong Kong in order to strengthen the scientific collaboration between Hong Kong and France. A 2 to 3 year scholarship covering travel, living and university registration expenses will be available for students and post-doctoral fellows resident in Hong Kong wishing to perform research work in laboratories of Institut Pasteur Paris. A lecture series of Pasteur scientists is organised to enable Hong Kong students to meet personally principal investigators from Institut Pasteur, know their scientific work and prospects of pursuing scientific work in their laboratories.
