I am a senior lecturer in Maternal and Fetal Health having previously completed my MRC Career Development Award Fellowship. My research is focused upon stillbirth and fetal growth restriction and improved understanding of the placental mechanisms that underpin these complications of pregnancy. Specifically, my research aims to:

- determine how placental function is altered in higher-risk populations including women of advanced maternal age

- identify and test candidate therapies for Fetal Growth Restriction.

- understand the role of fetal-placental interactions and their contribution to Fetal Growth Restriction

I am the programme director for MSc Reproduction and Pregnancy (Research) https://www.manchester.ac.uk/study/masters/courses/list/19778/msc-reproduction-and-pregnancy-research/ and Deputy Head for the Division of Developmental Biology and Medicine. 

Mark Dilworth undertook his PhD in the Faculty of Life Sciences, University of Manchester, focusing on renal physiology and how the transplantation of developing kidneys (metanephroi) may act as a possible intervention in renal failure. This PhD was part funded by a CASE award, which resulted in him spending a substantial period of time with an industrial partner, Intercytex Ltd. This link to industry built upon previous experience at GlaxoSmithKline, Hertfordshire where he spent a year as part of his BSc undergraduate degree. As part of his PhD, Mark also spent time in Aarhus, Denmark under the guidance of Professor Jens Nyengaard where he developed skills in stereological approaches.

Following discussions at a Physiological Society meeting with members of the Maternal and Fetal Health Research Centre, University of Manchester, Mark developed an interest in the physiology of pregnancy and eventually moved there as a post-doctoral fellow under the supervision of Professor Colin Sibley. Here, Mark developed a passion for translational research investigating causes and treatments for Fetal Growth Restriction, a major contributor to stillbirth and childhood and adulthood diseases. This work has resulted in him spending time at the University of Alberta, Canada (in the lab of Prof Sandra Davidge) and in him publishing several papers, including one in PNAS  which stoked an interest into the role of fetal nutrient demand and the failure of the placenta to adapt to these fetal signals as a causative factor in FGR.

In 2013, Mark was awarded a prestigious MRC Career Development Award Fellowship. Mark has continued to secure research funding and specialises in improved understanding of the mechanisms underpinning placental dysfunction in Fetal Growth Restriction and Stillbirth. He has a reputation in the use of pre-clinical models to assess candidate therapies for these complications of pregnancy.

In 2018, Mark was appointed as lecturer in Maternal and Fetal Health and became programme director for MSc in Reproduction and Pregnancy (Pregnancy). He became Deputy Head of the Division of Developmental Biology and Medicine in 2022. In 2024, Mark was promoted to Senior Lecturer.

The placenta is essential for transferring nutrients from mother to fetus. When this transfer is inadequate it can lead to poor growth of the fetus in the womb and a baby of low birth weight (fetal growth restriction, FGR). Such babies are at much greater risk of stillbirth and childhood and adulthood morbidities. Babies that are small for gestational age have been shown to have a higher incidence of diabetes and cardiovascular diseases later in life, demonstrating that poor growth in utero can have lifelong consequences. There are currently no treatments for poorly growing fetuses, other than early delivery. In order to rectify this we need to understand more about the way that transfer across the placenta is controlled and also investigate models of FGR/stillbirth in which we can test therapeutic strategies in the future. I am particularly interested in the role of fetal-placental signalling and how these interactions may fail in FGR, and also the placental mechanisms underpinning the increased risk of FGR and stillbirth in advanced maternal age.
