Research Interests

Research summary
I continue my research at the University of Cambridge. I am interested in the physiological mechanisms by which poor environmental conditions during pregnancy reduce the weight of the newborn and ultimately program offspring phenotype. My ongoing studies investigate regulation of maternal-fetal nutrient transport by glucocorticoid stress hormones in pregnant rodents and large animals. Endocrine and metabolic parameters are manipulated and measured directly in the mother and fetus whilst placental nutrient transport and uterine/umbilical blood flows are determined using in vivo radiotracer techniques. These observations are related to changes in epigenetic marks, gene and protein expression, and structure in fetal tissues, particularly the placenta.
