Overview
Amy Graduated from University of Exeter Bsc Medical sciences programme in 2018, starting a PhD under supervision of Tim Frayling and Andy Wood, investigating how genetic and lifestyle factors have an interactive effect on BMI. She is also interested in how these interactions may have either an adverse or protective effect on other implicated disease outcomes and metabolic profiles.
Aside from her academic interests, Amy is keen on sports, playing piano and guitar, baking and cocktail making!

Genome-wide association analyses of chronotype in 697,828 individuals provides insights into circadian rhythms
Using genome-wide data from 697,828 UK Biobank and 23andMe participants, we increase the number of identified loci associated with being a morning person, a behavioural indicator of a person’s underlying circadian rhythm, from 24 to 351. Using data from 85,760 individuals with activity-monitor derived measures of sleep timing we demonstrate that the chronotype loci influence sleep timing: the mean sleep timing of the 5% of individuals carrying the most morningness alleles is 25 minutes earlier than the 5% carrying the fewest. The loci are enriched for genes involved in circadian regulation, cAMP, glutamate and insulin signalling pathways, and those expressed in the retina, hindbrain, hypothalamus, and pituitary. Using Mendelian Randomisation, we show that being a morning person is causally associated with better mental health but does not affect BMI or risk of Type 2 diabetes. This study offers insights into circadian biology and its links to disease in humans.
