ECR Spotlight is a series of interviews with early-career authors from a selection of papers published in Journal of Experimental Biology and aims to promote not only the diversity of early-career researchers (ECRs) working in experimental biology during our centenary year, but also the huge variety of animals and physiological systems that are essential for the ‘comparative’ approach. Estelle Moubarak is an author on ‘ Artificial light impairs local attraction to females in male glow-worms’, published in JEB. Estelle is a Postdoctoral Research fellow in the lab of Jeremy Niven at University of Sussex, UK, investigating visual ecology and physiology of nocturnal insects and the impact of artificial light pollution on individual fitness.
