I study insects that eat plants.
Insects have eaten plants for around 400 million years. Over the past 12,000 years, humans disrupted these relationships by building cities, domesticating crops, and changing the global climate.
I investigate these disruptions, focusing on plants that are important to people -- such as street trees, crops, and crop wild relatives.
Right now, I'm fascinated by the hundreds of millions of pressed plant specimens that have been collected since the 1700s. These specimens hold clues to changing plant-insect interactions over centuries. For details, see current projects.
