Personal profile


Lecturer in Maternal & Fetal Health

Lead for Social Responsibility - Division of Developmental Biology and Medicine


Following my undergraduate degree in Microbiology and Immunology at The University of Leeds (1998-2001), I took a Research Assistant position at The Maternal and Fetal Health Research Centre (MFHRC), University of Manchester, investigating infection in the placenta. I moved on to a Wellcome Trust Prize PhD Studentship within the MFHRC which began my path of research into placental development and function and how these are regulated. My PhD was awarded in 2006 and I have since remained committed to continuing with my research into this important aspect of human biology. I have also been involved in more translational research projects, working towards developing treatments for improving pregnancy outcome in cases of severe fetal growth restriction and pre-eclampsia. I am now further developing my own ideas relating to the importance of taurine in the placenta and understanding how this amino acid influences placental mitochondrial function.

Research interests

My past research within the Maternal and Fetal Health Research Centre has mainly focussed on placental function with a particular emphasis on nutrient transfer. This research highlighted alterations to placental transport of the amino acid taurine in the pregnancy complications of fetal growth restriction (FGR) and pre-eclampsia (PE). Furthermore, placental taurine transport is reduced in maternal obesity which is a risk factor for development of FGR and PE during pregnancy.

Taurine is an unusual amino acid in that it is not metabolized nor incorporated into cellular proteins, suggesting that it could be important for cellular cytosolic function. Taurine is an osmolyte and in many cell types regulation of cellular hydration state is essential for proliferation, differentiation, apoptosis, and hormone secretion. Each of these processes are vital for normal placental development and function and therefore successful pregnancy outcome. Taurine is also an antioxidant and protects against inappropriate apoptosis, ischaemia/reperfusion, oxidative stress and cytokines. The mechanism by which taurine exerts its cytoprotective effect and how this amino acid modulates oxidative stress has been enigmatic. However, in non-placental cells there is evidence that taurine promotes mitochondrial function and I am interested to determine whether this is also true in the placenta.

Abnormalities in placental mitochondria are evident in FGR and PE, and in women at increased risk of these pregnancy complications. My current programme of research focusses on elucidating if mitochondrial dysfunction contributes to placental insufficiency in FGR and explore the possibility that targeting mitochondrial dysfunction therapeutically will improve placental function and fetal growth.
