Research Interests

Developmental Origins of Heart Disease

We work with small and large animal models to investigate the effects of adverse pregnancy on the development of the heart and circulation and in programming cardiovascular disease in the adult offspring.  We are able to study the cardiovascular system using an integrative approach at the in vivo, isolated organ, cellular and molecular levels. 

We have a particular interest on the effects of hypoxia during embryonic and fetal development and its long-term consequences for cardiovascular risk in the adult offspring.  In larger animals, such as sheep, we are experienced fetal cardiac surgeons and we can surgically prepare the pregnant ewe and fetus for long-term cardiovascular recording with blood pressure catheters and Transonic flow probes around vessels of interest, like the uterine, umbilical artery, fetal carotid and fetal femoral artery.

In sheep, rats, mice and chickens we combine our in vivo surgical expertise with echocardiography, isolated Langendorff and Working Heart preparations as well in vitro wire myography to determine changes in the reactivity of isolated blood vessels.

Our research group has pioneered the role of prenatal hypoxia and oxygen species in fetal physiology and in programming cardiovascular disease in later life.  Our landmark discoveries are, showing that the circulatory response that protects the fetal brain during hypoxia is triggered exclusively by the carotid body, establishing that hypoxia restricts fetal growth and identifying resistance against this in Andeans, elucidating that hypoxic pregnancy accelerates cardiovascular ageing in the offspring; effects prevented by maternal antioxidant treatment.  We have developed wireless technology to record materno-fetal continuous cardiovascular data from sheep undergoing hypoxic pregnancy; an advance opening the scientific possibilities of fetal physiological research.
