[1] He is Director of Communications and Engagement at the Royal Entomological Society and Insect Week Coordinator in the UK.
[4] He received his Ph.D from the University of York in 2010, studying the parasitoid wasps of shore flies in lettuce and celery crop glasshouses.
[6][7] Tilley's research looked at the parasitoid wasp Aphaereta debilitata as a biological control agent of the shore fly Scatella tenuicosta, a pest in glasshouse crop soil.
He found that the wasps reduced numbers of flies emerging from soil and subsequently there was a decrease in lettuce damage levels.
[8] He also found that levels of algae growing on the soil were negatively correlated with A debilitata and concluded that growers should encourage algal growth, as part of a conservation biological control programme.
