Research

The aim of our laboratory is to understand how prenatal perturbations contribute to an increased risk of developing cardiovascular, renal and metabolic disease in adulthood. Over the last 5-7 years, our research has focused on determining the pivotal role played by the kidney in the developmental programming of adult disease. This research has shown a reduced nephron endowment is associated with hypertension and renal impairment in the adult following excess maternal glucocorticoid exposure, maternal low protein diet, placental insufficiency and most recently, prenatal alcohol exposure.
