Research Interests

My general research interests are in plant reproductive biology and plant development. I am also interested in science advocacy and the relationship between religion and science.

Current Projects

My research falls into the areas of angiosperm reproductive morphology and development and pollen biology. I am particularly interested in understanding how evolution in the morphology of reproductive structures, such as the carpel or the pollen grain, affects their function. For example, the flower is tremendously diverse and comes in many shapes and sizes. Much of this diversity arises due to adaptations to attract pollen and/or pollinators, which is an important function of the flower. However, at the same time, flowers must also mediate pollen germination and the development of a pollen tube that carries the sperm to the egg. Changes in flower size, shape, or ultrastructure can affect how development of the pollen tube proceeds. I use both field experiments and microscopy techniques to determine the timing of reproductive events and the pattern of reproductive development. Most of my work to date has been with in water lilies (Nymphaeales), one of the oldest groups of flowering plants. However, I am interested in investigating these processes across all angiosperms.
