Her work has looked at how plants interact with insects and how this can be manipulated to reduce the attraction of crop plants to insect pests. She tested gene edited rice plants which suppress the production of serotonin with an inactivated ''CYP71A1'' gene, the plants were more resistant to the brown plant-hopper and the striped stem borer. Her team identified that the compound
