Reproduction is the most fundamental aspect of success for any living organism. A major part of the evolution of different reproductive strategies involves sexual selection — the competition by males to fertilize an egg or the choice by females for particular males. However it is still unclear the extent to which this occurs in plants, both because they often have male and female parts in the same flower, and because they are sessile and rely on pollinators to transfer male gametes.  Several projects in the lab investigate the relationship between female and male gametes, and/or female and male parts of the flower.

1. Avoiding selfing, and interference between male and female parts, in hermpaphroditic plants 
2. Sex allocation theory and allocation to male and female function
3. Interactions between pollen grains and pollen tubes with the style and ovules
