Research Interest Summary

interrogates the roles of fibroblast growth factor receptors and their adapters in kidney and lower urinary tract development.

Research Interests

My research program is focused on genetic mouse models of kidney and urinary tract development, given that congenital kidney diseases are the leading causes of chronic kidney disease in children. One major project is focused on the role of fibroblast growth factor receptors in kidney development. Using conditional knockout and receptor point mutation approaches, we have uncovered many different roles for Fgfrs in different lineages within the kidney. Many of these mice have features that mimic structural kidney disease in children including renal aplasia, hypoplasia, and progressive cystic disease. Recently we have data showing that Fgfrs are critical for maintenance of nephron progenitors, the stem-cell like cells that eventually form nephrons in the kidney. This work has been supported by an NIH R01 grant that we recently successfully competed for. 
A second major project in the lab is focused on our observations that Fgfr2 is critical for normal ureteric bud induction, ureter function, and bladder function. Mice with deletion of Fgfr2 in the mesenchymal cells in these tissues develop high rates of vesicoureteral reflux (backflow of urine from the bladder to the kidney), ureter contractile defects, and bladder defects including high pressure, low capacity bladders. As the mice age, they develop scarring in the kidney, which mimics reflux nephropathy, another leading cause of chronic kidney disease in children. 

I have other NIH funded projects in the lab; one is as a co-principal investigator on an NIH R01 grant focused on the “megabladder” mouse that has a severe defect in bladder muscle formation, leading to in utero obstructive nephropathy, another leading cause of renal failure in children. I am also a co-investigator on an R01 investigating how bone morphogenetic proteins and fibroblast growth factor receptors interact in nephron patterning. As we have generated these mice and learned about the actions of fibroblast growth factor receptors in the kidney, we have considered examining DNA collected in children with structural kidney diseases for permutations in Fgf ligands and/or Fgf receptors (ranging from single nucleotide polymorphisms to larger copy number variations).
