    Research Overview

    Over five decades of research have uncovered most of the molecular machinery that executes cell division. Reductionist approaches have been essential in tackling the complexity of this machinery. However, complex processes such as mitosis also rely on emergent functions. We aim to discover emergent mechanisms of the mitotic machinery using an integrative approach. We engineer novel tools and techniques to enable quantitative investigations of mitotic events in live cells. We use these quantitative data to build mechanistic, mathematical models to gain a deeper understanding of the biology and the biological design of the complex cell division machinery. Currently, there are two major research themes in the Joglekar lab. We are investigating the systems biology of the Mitotic Checkpoint, which is the cell cycle control that ensures accurate chromosome segregation. We are developing novel assays to quantitate the biochemical signaling cascade underlying the mitotic checkpoint and build a detailed mathematical model that describes the signaling dynamics of the checkpoint. This quantitative, mechanistic description of the mitotic checkpoint will allow us to understand and predict its perturbation in cancer cells. Under the second exciting theme, we will reverse engineer the yeast kinetochore – the macromolecular machine that moves chromosomes, using de novo-designed proteins.
