Biography

Following his BSc Hons and PhD in Zoology, Professor Fowler worked on ovarian hormones in Obstetrics & Gynaecology, 51cg. In 2000, he moved to the 51cg’s Institute of Medical Sciences and was its director for 6 years (2015-21). His work elucidates mechanisms regulating/dysregulating reproduction and development. He has over 170 peer-reviewed publications and book chapters and co-authored numerous European Food Standards Agency opinions. Since 2000, his research focused principally on effects of environmental/lifestyle exposures, including maternal smoking, obesity, and medication use. This aims to understand disruption of fetal development and health, principally using normal first and second trimester human fetus. Since 2009 he has led/participated in 4 large EU research programmes studying endocrine disruption and received MRC, BBSRC, Wellcome Trust, charities and PARC (Partnership of the Assessment of Risks from Chemicals, 2022-2029) funding. In 2023 he was awarded the Anne McLaren Distinguished Scientist award by the Society for Reproduction & Fertility.

Research Overview

Since the breakthrough epidemiological studies of the 1980s it has been clear that adult human health is dependent upon fetal development and fetal programming (‘early life programming’). Fetal growth restriction, for example, can lead to hypertension, type 2 diabetes, obesity and cardiovascular disease in the adult. This fetal programming is also termed "Developmental Origins of Health and Disease" (DOHaD) or "Fetal Origins of Adult Disease. Dysfunctional changes in the fetus can arise through a range of mechanisms, such as:

• maternal cigarette smoking
• maternal obesity
• maternal deprivation
• maternal nutrition
• maternal environmental pollutant exposure (such as air pollution)
• maternal medication use

We are studying these factors primarily in the human itself, by studying fetuses aborted for non-medical reasons. This is supported by the SAFeR Study (Scottish Advanced Fetal Research study).

The health trajectory of an individual offspring is likely to depend upon a range of maternal and lifestyle factors, including the chemical burden carried at birth. Fetal pollutant exposure has clear adverse effects on development but we have very little knowledge about levels of fetal exposure to “real-life” complex pollutant cocktails and developmental consequences. This fundamental lack of knowledge is a major impasse to developing strategies for reducing fetal pollutant burdens and predicting likely health outcomes. Available data is limited, and often indirect (i.e. animal models or surrogates of exposure), but all studies suggest that fetal pollutant exposure affects lifelong health outcomes and, thereby, impacts on the general economy.

As well as laboratory-based studies of the human fetus my group has also become involved in epidemiological studies in the same field. Our intention with this move is to improve linkage between the individual fetus/mother (laboratory) and population-wide (epidemiology) analyses of maternal environment/lifestyle effects on the fetus and its future health.

Our aim is to understand how maternal factors disturb human fetal development, leading to offspring with greater risk of adverse health outcomes.

Our objective is to identify mechanisms linking these maternal factors with sub-optimal fetal development and lifelong health burdens.
