My research group is focusing on hybridization and reproductive isolation, taxonomy, conservation as well as breeding of Rhododendron for several years. I have carried out plenty of field works with regard to endangered species covered by the red list. We rediscovered the famous species R. griersonianum that had not been reported again in the recent 70 years. Moreover to resolve conservation issues in-depth for the critically endangered R. griersonianum,we carried out the whole genome sequencing of it and finally get a chromosome level genome. Now I am also working on phylogeny study of Rhododendron distributed in China using NGS.
