Plants and insects comprise the majority of the world’s biodiversity. How has the interaction between plants and insects given rise to the incredible diversity of both groups? My research interests lie in understanding the ecological and evolutionary consequences of plant-insect interactions. Plants interact with the world primarily through the means of chemistry and produce a diverse array of chemical compounds that can serve important ecological functions by protecting the plant from herbivory or attracting pollinators. As a post-doctoral researcher at the Chicago Botanic Garden, I examine the role of floral scent in mediating interactions with hawk moth pollinators and herbivores in the evening primrose family, Onagraceae. In at least two species, floral scent shows substantial geographic variation and we hypothesize that this geographic variation is a consequence of differential herbivore and pollinator selection. I am also interested in how plant-insect coevolution has resulted in in rapid adaptive radiations (speciation) in plants. As a part of my post-doctoral research, I explore the importance of herbivores, pollinators and floral scent in the diversification of Onagraceae.

Floral traits at the intersection of herbivory and pollination in evening primroses (2017)

The Dimensions of Biodiversity: Landscapes of Linalool grant broadly examines the role of floral scent in mediating pollinator and herbivore interactions and in driving the diversification of evening primroses at multiple evolutionary timescales. Due to their opposing effects on plant fitness, herbivores and pollinators have the potential to influence the evolution of floral phenotypes across...


Floral trait variation in evening primroses (Onagraceae) (2016)

The evening primrose family, Onagraceae, shows spectacular inter- and intra-specific variation in floral morphology, floral scent and mating systems. As part of a large NSF-funded Dimensions of Biodiversity project, we have documented both inter- and intra-specific variation in floral traits in 14 species of Onagraceae and have found striking intraspecific polymorphisms in many taxa. In these...


Scent variation: its role in attracting both pollinators and herbivores in Evening Primroses (2015)

The plant tribe Onagreae (Onagraceae; the evening primrose family) and its associated insects pollinators (Sphingidae hawkmoth) and herbivores (Mompha microlepidoptera and Hawkmoth larvae) is a model systems for studying the role of floral scent in shaping the evolution of plants and their associated organisms across western North America. Floral scent is known to be an important trait in...


Scent variation: its role in attracting both pollinators and herbivores in Evening Primroses (2014)

The plant tribe Onagreae (Onagraceae; the evening primrose family) and its associated insects pollinators (Sphingidae hawkmoth) and herbivores (Mompha microlepidoptera and Hawkmoth larvae) is a model systems for studying the role of floral scent in shaping the evolution of plants and their associated organisms across western North America.
