The main focus of my group is to understand the molecular and cellular basis of myopathies and neurodegenerative disorders. We use two genetically tractable model organisms, Drosophila melanogaster (fruit fly) and Danio rerio (zebrafish), to trace the etiology of these diseases and dissect the associated mechanisms. We are also interested in identifying host factors responsible for host-pathogen interactions. We use genetic tools and transgenic approaches to identify novel factors and decipher pathways underlying normal development and those which lead to the manifestation of diseased conditions. Experimental approaches include genetic, molecular, biochemical and biophysical assays, electron and confocal microscopy and behavioural tests.Main research areas of interest are: Muscle; Neurobiology; Immunity, Drug screening and biomechanics.
