Insects have eaten plants for around 400 million years. These interactions have given rise to most of terrestrial biodiversity. Over the past 12,000 years, humans have disrupted plant-herbivore relationships by building cities, domesticating crops, and changing the global climate.
I investigate these disruptions, focusing on species that are of cultural importance, such as street trees, crops, crop wild relatives, and plants that support rare insect species. My work combines experiments, observations, citizen science, and biological collections to address key hypotheses in ecology.
