Cell Migration
Proper regulation of cell migration is crucial for many biological processes including organ development, tissue repair and the immune response. Defects in cell migration play a central role in developmental disorders, neuronal disorders, tumorigenesis, immune disorders and cancer metastasis. Fundamentally, cell migration is regulated though small adhesive structures across the cell that assemble and disassemble allowing the cell to translocate. My lab applies advanced light microscopy tools including image correlation microscopy in order to understand the molecular mechanisms that spatially and temporally regulate adhesions and control cell migration. An understanding of these fundamental mechanisms will lead to new insights into what causes migration related defects and disease. We are specifically interested in understanding cell migration defects that cause breast cancer cell invasion and metastasis.

Instrument Standardization and Quality Control
As the
Director of the McGill University Life Sciences Complex Imaging Facility we are developing protocols and standards for testing the quality of light microscopes. We have developed protocols for measuring laser stability, microscope alignment, resolution, and objective lens quality. We are leading world wide studies on instrument quality and publishing detailed protocols enabling microscopists world-wide to validate and maintain their equipment. These tests are applied routinely to all of the microscopes within the facility ensuring researchers are working on top performing equipment.

Imaging Facility
The facility has
13 state-of-the art light microscopy platforms used by ~150 users from 60 laboratories across Montreal to conduct their microscopy based research. The facility has expertise in many areas including live cell imaging, total internal reflection fluorescence (TIRF) microscopy, fluorescence lifetime imaging microscopy (FLIM), multi-photon microscopy, laser micro-dissection, fluorescence correlation spectroscopy (FCS), image processing and analysis, spectral imaging and high content screening. We have also developed and run more than 30 workshops and courses, in collaboration with corporations in the field of light microscopy, including the inaugural Montreal Light Microscopy Course (MLMC) in 2010. MLMC 2012 was also a great success. The next MLMC will be July 7-18, 2014.
