The Choksi Lab studies how airway stem cells differentiate to build and maintain the respiratory epithelium. We focus on multiciliated cells - specialized epithelial cells that protect the lung by clearing inhaled pathogens. By combining mouse genetics, single-cell technologies, and imaging-based approaches, we aim to uncover novel principles underlying multiciliated cell differentiation. Our long-term goal is to identify new therapeutic strategies for restoring cellular function in respiratory disease.
