We are proud and excited to have renewed our NIH R01 grant entitled “Mechanisms of Cell Shape Change in Cytokinesis.” This funding will allow us to explore the molecular and mechanical mechanisms of time-delayed negative feedback in the actomyosin contractile cytoskeleton that underlie the dynamics we recently discovered, including speed oscillations. Current lab members Michael Werner, Daniel Cortes, and Katie Rehain-Bell contributed the preliminary results that made this proposal a success.
