Research Area
Evolution, systematics and conservation of plants
Research Description
My research concentrate on the use of molecular markers in evolutionary and conservation biology, especially hybridisation, polyploidy, the evolutionary consequences of human-mediated plant movement and conservation genetics.
I am also interested in the problems of using herbarium specimens as a source of DNA for evolutionary studies, and the history of botany.
