Dr. Skalli is a cell biologist whose research interest is the cytoskeleton, an intracellular
network of filaments and tubules central to cell motility, cell division, cell shape
determination, and organelle trafficking. The use of microscopy is central to Dr Skalli’s
research, whether it is conventional light microscopy to examine by immunoperoxidase
or immunofluorescence the distribution of specific proteins in tissues, or confocal
laser fluorescence scanning microscopy to investigate the distribution, interaction
and function of diverse cytoskeletal proteins in cultured cells. Dr. Skalli also uses
electron microscopy to address questions related to the mechanisms by which cytoskeletal
proteins assemble to form filaments and tubules. In addition to microscopy, Dr. Skalli
expertise includes tissue culture, DNA cloning and expression in cells, as well as
several biochemical methods such as Western blotting, protein purification, and immunoprecipitation.
Dr. Skalli orversees the organization and the development of the Integrated Microscopy
Center and assists users interested with projects involving cell culture methods and
light microscopy with their experimental design, data interpretation and troubleshooting.
Dr. Skalli is also Associate Professor in the Life Sciences Department, and teaches
a graduate course on “Light Microscopy: Theory and Applications”. This course exposes
students to the various modalities of light microscopy, ranging from classical bright
field microscopy to state of the art methods such as super-resolution. The course
also involves a practical component during which students are trained in histology
and immunofluorescence staining methods and in using light, fluorescent and confocal
laser scanning microscopes.
