seeing is believing
We are fascinated with dynamical systems in lung injury and regeneration. Changes in chromatin and gene regulation drive changes in cell state and behavior that ultimately drive lung repair or, in some cases, disease. Our lab uses an array of different approaches to investigate these changes, from single cell multi-omics to live in vivo imaging of individual cells in the lung. Our ultimate goal is to uncover mechanisms that govern stem cell fate and function in the lung, and how these are modulated in the context of disease.
