Research InterestThe timing for intervention in obstruction in the infant and child is poorly understood.Our group has been interested in trying to define the risks that may be involved in obstructive and infectious uropathies and discovering early signs of damage to the urinary tract and kidney. We have explored ways of imaging the urinary tract using nonionizing radiation (US, MRI). We have studied the relationships of sex steroid hormones, pregnancy, reflux, urinary tract infection and urinary tract function.

- Bladder Cancer
Research InterestMy research focuses on outcomes in the treatment of muscle invasive and high-grade non-muscle invasive bladder cancer. This includes identifying markers of prognosis, predictive markers for response to surgery and chemotherapy, and working toward an individualized, multidisciplinary approach to disease management. I have also focused on optimizing the use of lower urinary tract reconstruction in patients undergoing cystectomy, and developing interventions to improve patient quality of life.

Associate Professor, Genetics
Research InterestMy lab focuses on understanding the molecular mechanism of transcription factors that govern the transformation of normal mammalian cells to a neoplastic state. We are especially interested in the action of the nuclear hormone receptors and the interactions between the receptors and other signaling pathways in related human disorders.
