Research Collier's research looks a new techniques to control insect pest insects of horticultural crops, in particular the use of integrated pest management.

Her work has looked at how to deter pest insects away from food crops to prevent them feeding and causing economic damage, such as such as by providing green areas near the crop on which for them to land, by companion planting with flowering plants such as clover to draw insects away from brassicas, or by applying volatile compounds to change the scent profiles of food crops.

She also provides advice on how weather can affect pest insect populations and how it can influence insect behaviour.
