Research Summary:

Twin pregnancies are about five times more likely to be complicated by premature birth, preeclampsia, fetal growth restriction, and other pregnancy complications compared with singleton pregnancies. This, in turn, results in a considerable risk of death and illness for both mothers and infants.

Dr. Melamed is head of the Twins Research Centre at Sunnybrook. His research is focused mainly on improving the understanding of the mechanisms of pregnancy complications, fetal growth, and prediction and prevention of preterm birth in twin pregnancies. This work is supported by the Waugh Family Chair in Twins Research held by Dr. Melamed, and by a $1.5 million Canadian Institutes of Health Research Team Grant on noncommunicable diseases in obstetrics.

His research also focuses on placental disease and fetal growth. He uses various approaches including biochemical markers, noninvasive cardiac monitoring, ultrasound and Doppler studies, and placental pathology.
