Research Abstract:

The goal of my laboratory is to decipher molecular and genetic mechanisms that confer specificity in development and diseases of the urogenital and nervous system. We are investigating mechanisms of how genetic variants cause congenital genitourinary malformations, and the role of developmentally important genes in repair and regeneration in adult acute and chronic diseases, and cancers of the GU system. Within this framework we seek to understand how different epithelia come together to connect organs, the expression pattern changes at a single cell or in selected population of cells that form the basis for maintaining the progenitor stage or their differentiation into specific lineages in normal and disease states. We heavily use genetically engineered mice, injury models, organ cultures, isolation of specific populations from normal and disease structures, and human iPSC cells as model systems. Our research program is supported by grants from the NIH, March of Dimes Foundation and Washington University.
