About Me

I study how anthropogenic disturbances such as land management activities, invasive species, and pollution (including fertilizers and pesticides) impact biodiversity and species interactions, and how these changes to biotic communities in turn affect ecosystem processes, such as nutrient and energy flow through food webs, organic matter decomposition, plant pollination, and seed dispersal. My particular focus is on arthropods and their direct and indirect interactions, and in particular, taxa whose direct interactions with other species can be feasibly detected and quantified, such as plant-caterpillar-parasitoid interactions, plant-aphid-parasitoid interactions, spider-parasitoid interactions, ant-plant interactions, plant-gall-inquiline interactions, bee/wasp-parasitoid interactions, and plant-pollinator interactions.
