Areas of research focus

  • Evolution of reproduction in gymnosperms
  • Experimental embryogenesis of conifers
  • Proteomics of gymnosperm sexual fluids

The study of evolution of plant reproduction by seed begins with pollen-ovule interactions. In gymnosperms, e.g. conifers and cycads, pollen delivered by wind or animals is captured by a pollination drop . By looking at the chemical profiles of these drops, researchers in my lab hae discovered a number of adaptations involved in eithe defense and rewards.
