[2] In 2012 he was awarded a DSc from the University of Nottingham in recognition of his contribution to research into the early life origins of adult disease.
His principal contribution was the development of experimental models to test the hypothesis that variation in maternal nutrition during pregnancy could programme long-term health and disease.
[3][4] A long-term champion of equality, diversity and inclusion, for which he was awarded the Vice Chancellor's Medal [5] in 2016, Langley-Evans has been outspoken in criticising declining standards of scholarship in the nutrition field [6] and has written about the lack of care taken by the academic community to prevent burnout and poor mental health.
[7] In addition to publishing more than 150 papers in scientific journals[8] and has contributed to several books on early life programming as editor[9] and author,[10][11][12][13] Langley-Evans is the author of an academic textbook entitled Nutrition, Health and Disease: A Lifespan Approach,[14][15][16] of which the third edition was published in 2021, and was the longest-serving editor-in-chief of the Journal of Human Nutrition and Dietetics between 2012 and 2023[17].
Outreach work to further understanding of nutrition science has included participation in I'm A Scientist Get Me Out Of Here and provision of specialist advice for a children's book.
