I am broadly interested in the Andes as a region, especially how diversification and evolution have occurred in the dry Inter-Andean valleys. I’m keen on understanding biogeographical patterns and the effects that varied reproductive strategies (polyploidy, apomixis, various levels of selfing) have had on diversification.
