Biography
Dr. Maithreyi Narasimha is an assoicate professor in the School of biological sciences , Her work is based on Cells in tissues exhibit stochastic and collective behaviors and seem capable of "self-organization". What drives distinct cell behaviours? How do cells sense their neighborhood and adapt to perturbations (like cell division, death, wounds) they encounter? What rules do they follow when doing so? Cells communicate using a combination of chemical and physical cues and "cell junctions" containing adhesion molecules can transduce both. How do contact or chemicals mediate changes in cell behavior? Do they work alone or together? We study design principles of cellular reorganization accompanying Drosophila morphogenesis and mouse embryonic stem (ES) cell differentiation using a combination of genetics, live confocal microscopy, biophysical perturbations, computational and theoretical approaches facilitated by quantitative analysis and collaborations with theoretical and experimental physicists.
Research Interest
Cell adhesion, Epithelial morphogenesis and Cellular reorganization.
