Coordinator of the Selaginella genome sequence and its comparison to other plant genomes. See website: for more information

Molecular basis of arsenic hyperaccumulation in the fern Pteris vittata. This fern is amazing as it tolerates and accumulates a lot of arsenic in its fronds. We will continue to discover and study the genes that are involved in this unusual trait.

Sex determination by pheromones in plants and the fern Ceratopteris in particular. Ceratopteris gametophytes develop as hermaphrodites or males, a decision dictated by a pheromone. We are using genetics and genomics approaches to understand how this pheromone regulates this important decision.
