Our three main axes of research are:
- Ecology and genome size and variation: we study how ecological pressures (e.g., abiotic stress) affect the evolution of transposable elements, genome size, and influence trait and plant fitness. We use species of the genus Solanum as models.
- Population genomics: we investigate how wild relatives of crops can be used to address food security and improve the resilience of their domesticated relatives. We will be expanding in this research area, focusing on more wild species in the genus Solanum that span diverse ecological gradients.
- Macroevolution and biogeography: we aim to understand the mechanism and processes behind the diversification of plants over large time scales.

My research program investigates the ecological and evolutionary processes operating in plant populations, both wild and domesticated. Much of our work is conducted through the lens of plant reproductive systems, which control the quantity and quality of sperm and eggs, patterns of mating, and ultimately the transmission of genetic variation from one generation to the next. Current research projects include: 1) mating system variation and evolution, 2) polyploid speciation, 3) genetic and phenotypic consequences of whole genome duplication; 4) biology of small populations, and 5) impacts of hybridization between introduced species and endangered congeners. We work on a variety of study systems, including Arabidopsis, apple, strawberry, fireweed, American chestnut, and mulberry.
