Title: Courtship is a Two-Way Conversation: Yeast Mating as a Model of Cell-Cell Communication Abstract: Many cells track chemical signals, but mechanisms of target location are elusive. The budding yeast, an established model of cell-cell communication, tracks a pheromone signal…

Title: Modeling post-transcriptional regulation and large deviations in stochastic gene expressionAbstract: In diverse cell populations, phenotypic variations are often observed even among genetically identical cells in a homogeneous environment. Recent research indicates that such `non-genetic individuality' can be driven by rare events arising from…

Title: Mathematical Models for Extracellular Matrix Regeneration and Remodeling in Biological Soft TissuesAbstract: Many biological soft tissues exhibit complex interactions between passive (biophysical, biomechanical) mechanisms, and active physiological responses.  These interactions affect the ability of the tissue to remodel in order to…

Title: Waves and flows: Physical principles of organization of early embryogenesis and regeneration Abstract:  Embryonic development and tissue regeneration both require a high degree of spatiotemporal coordination. I will describe my lab efforts to understand the synchronization of the cell cycle in…
